Gentlemen:
I have the Power Point slides that Wing Tsang e-mailed and I thank you for those.
Slide 5 depicts boiling modes. Are the photographs of boiling in your apparatus? I saw no provisions for that in your proposal or in the subsequent Power Point slides. Slide 5 includes nucleate and film boiling plots: Please tell me the units for the ordinate. I presume that the fluid was methanol and the system pressure was about one atmosphere. I also presume that the surface temperature was measured with an interior thermocouple.
Was fouling of any of the heat transfer elements observed, if so, how much?
Please tell me about the operating efficiency. As a first cut at this, what was the power consumption of the heat transfer element? I would like to see a plot of watts per cubic centimeter of hydrogen (ordinate) and hydrogen production rate (abscissa) for both methanol and ethylene glycol.
Thank you for your cooperation, and I will likely have further questions. I am attaching your Power Point file for the convenience of the NSF addressees.

I would like to see a plot of watts per cubic centimeter of hydrogen (ordinate) and hydrogen production rate (abscissa) for both methanol and ethylene glycol.
Some generic expressions of praise
His discoveries in the late 1980s and early 1990s alone should have earned him a solid place in the history of experimental heat transfer, but in the years since then he has made these a foundation for several fantastic applications and further investigations..
Luck plays a role in his work, but more important is the series of uninhibited approaches that have baffled the "experts."
This award is presented annually for outstanding scientific achievements in experimental heat transfer that occurred in the past 20 years.
The annual award is for outstanding basic research in experimental heat transfer.
He won the 2008 Heat Transfer Achievement Award for Breakthrough Research.
The investigator could have been at the Generic University School of Engineering when he received the 2008 Humanitarian Award from the American Generic Association.

Leyse, UCLA, NSF, Congress and the Great American Handshake: An update.
It appears that the cartel of university officials has succeeded in gaining a preferred and somewhat closed access to NSF funding.
MESSAGE TO HOUSE COMMITTEE ON SCIENCE AND TECHNOLOGY
Section 3(e) of the National Science Foundation (NSF) Act of 1950, as amended, states that: "...it shall be an objective of the Foundation to strengthen research and education in the sciences and engineering, including independent research by individuals, throughout the United States, and to avoid undue concentration of such research and education."
I took my great technology to UCLA. Our proposal (my technology) was declined:
CBET 0438436MICROSCALE HEAT TRANSFER IN FLUIDS AT SUPERCRITICAL PRESSURES: EXPERIMENTS AND MATHEMATICAL MODELING
U of Cal Los Angeles
Declined 08/19/2004
Without my knowledge, UCLA then submitted Proposal Number 0553571 which was a modification of the above declined proposal, but which still had my great technology as its keystone. UCLA won $399,740. I was surprised to find this out when I scanned active awards at NSF.This certainly amazed me.
I asked NSF's OIG to look into this and recently I was told, “We opened a file in response to your email received in this office on April 17, 2008. We have determined that there is insufficient substance to an allegation of misconduct to proceed in this case. The case has been closed and no further action will be taken.”
I want the Committee on Science and Technology to investigate this situation.It appears that NSF avoids funding independent research by individuals. It appears that NSF resents such applications for funding. It appears that the cartel of university officials has succeeded in gaining a preferred and somewhat closed access to NSF funding.
I received no reply from the House Committee on Science and Technology, So I asked my Congressman, Mike Simpson, to get after these birds. He has done so, and I suppose that at some point I will get some kind of response. Anyway, here is an early response from Mike.
After a while Congressman Simpson wrote me that NSF responded:Below is the letter from the Inspector General of NSF to Congressman Simpson:
So, in response, I have recently sent the following to Congressman Mike Simpson with copies to NSF and UCLA:

Dear Mike:
Thank you for contacting NSF on my behalf. I have your letter of October 6, 2008, that included NSF’s response from its Inspector General.
She bottom lined, “I remain of the opinion that further investigation is unwarranted.”
Well Mike, a lot of further investigation of NSF by Congress is fully warranted. The NSF is effectively run by a cartel of university administrators.
The NSF statement that UCLA’s revised proposal did not include research proposed in the first proposal is false.
NSF sent you a copy of its recent Semiannual Report to Congress. The crimes that are disclosed in that report are trivial in comparison with what NSF and UCLA have done in my case. That report to Congress even refers to ethics. Well, NSF leadership as well as the Dean of Engineering at UCLA ought to be taught about the great American handshake.

Dear Inspector General:
Please audit the following claim by UCLA in its revised NSF PROPOSAL NUMBER 0553571, dated 09/14/2005, and let me know what you find out.
During the past decade we have always employed undergraduate students in our laboratory, giving many students from underrepresented groups the opportunity for hands-on experience in a state-of-the-art research facility. These students have left our laboratory better prepared for graduate level research.
That is, I would like to know how many undergraduate students were employed during each year, by year, from 1995 through 2004, their activities, the time worked, the fraction during each year from underrepresented groups, and the fraction from each year that went on to pursue graduate level research. Also, describe the coordination with UCLA’s Center for Excellence in Engineering and Diversity (CEED), founded during 1993, for each year.
As you may see below, NSF’s rejection of Proposal 0438436 was substantially based on the proposal’s lack of coverage of NSF’s Broad Impacts criteria.
Proposal Number:
0438436
Proposal Title:
MICROSCALE HEAT TRANSFER IN FLUIDS AT SUPERCRITICAL PRESSURES: EXPERIMENTS AND MATHEMATICAL MODELING
Received by NSF:
05/14/04
Principal Investigator:
Gopinath Warrier
Co-PI(s):
Robert Leyse
Vijay Dhir
Performing Organization:
U of Cal Los Angeles
The Program Director concurs with the findings of the Review Panel with respect to the Broad Impacts of the proposed research. This portion of the proposal is deficient. The PIs should refer to the Grant Proposal Guide so that they may properly address these issues. As it is, they have merely restated in one sentence the intellectual merit of the study in the Project Summary. The Project Description does not contain any discussion at all concerning the Broad Impacts criteria.
UCLA responded with claims as follows in its revised Proposal 0553571.
From the PROJECT SUMMARY:
Broader Impact of Proposed Activity
The project will support at least two undergraduate students from underrepresented groups to come and work in the laboratory each summer. This will give the students a chance to gain valuable hands on experience and stimulate their interest in the field of thermal science and engineering. Two Ph.D. students will also be supported as part of this project. The research accomplished will be presented at conferences and published in archival journals for general dissemination to the technical community.
From the body of the Proposal, Page C-13:
BROADER IMPACT
As part of this research project, we intend to support at least two undergraduate students from underrepresented groups to come and work on the project each summer. During the past decade we have always employed undergraduate students in our laboratory, giving many students from underrepresented groups the opportunity for hands-on experience in a state-of-the-art research facility. These students have left our laboratory better prepared for graduate level research. This program will be coordinated with the Center for Excellence in Engineering and Diversity (CEED) within the UCLA School of Engineering and Applied Science. Two Ph.D. students will also be supported – one for the experimental part and another for the mathematical modeling. Results of this study will be presented at conferences and published in archival journal for general dissemination to the technical community.
So, Inspector General, I believe you will agree that UCLA claims that it complies with NSF’s Broad Impacts criteria in its revised proposal 0553571. Certainly, this vital factor must be audited. Again, please let me know what you find out.

Sheenan and Her Gang
Anyway, we talked about this and that. One of the experts told me about derivatives and I wanted to talk about Warren Buffet and his reference to CDO's or whatever as the mother of all catastrophes, but I could not think of CDOs. I said the only thing I knew about derivatives was that the differential of x squared is 2xdx. And so we rambled all over the place.
I mentioned that I had a blog and the gang was amazed that I knew about such things. Next I identified this blog and one of the young geniuses dragged out his whatever and invited me to bring up the blog. I pleaded that the keys were too small, however, I dictated the address and we were soon on line right there on 2nd Avenue.
I could have driven that kind gang nuts by drifting all over this blog, but I focused on the pigeon at Radio Shack. As the text was read to the gang, I moved in view of all and acted out the capture and release of the pigeon with my great felt hat. As I left the scene to get back to my base at 400 East 85th, the gang allowed me to photograph the scene. What a great gang!
This quote from Mark Twain's PUDD'NHEAD WILSON, Chapter 19 has nothing to do with Sheenan and Her Gang, but I've been reading Mark Twain and decided to tuck away this great quote right here: Few things are harder to put up with than the annoyance of a great example.

Well, for some reason I got involved. I took off my quality black Pendleton wool hat and moved toward its perch on a higher shelf. The bird flew toward the front window, fluttered against that barrier and wound up on a lower ledge. I covered it with my hat, and with my other hand I captured the poor thing and then released it via the open front door.
A small crowd witnessed the scene and cheered as the pigeon flew to freedom. The young man smiled.
The weather is a great, clear and crisp; it is an ideal October day in Manhattan.

1 INTRODUCTION
On the 10th April 2003 severe damage of fuel assemblies took place during an incident at
Unit 2 of Paks Nuclear Power Plant in Hungary. The assemblies were being cleaned in a
special tank below the water level of the spent fuel storage pool in order to remove crud
buildup. That afternoon, the chemical cleaning of assemblies was completed and the fuel rods
were being cooled by circulation of spent fuel storage pool water. The first sign of fuel failure
was the detection of some fission gases released from the cleaning tank during that evening.
The cleaning tank cover locks were released after midnight and this operation was followed
by a sudden increase in activity concentrations. The visual inspection revealed that all 30 fuel
assemblies were severely damaged. The first evaluation of the event showed that the severe
fuel damage happened due to inadequate coolant circulation within the cleaning tank. The
damaged fuel assemblies were removed from the cleaning tank in 2006 and are stored in
special canisters in the spent fuel storage pool of the Paks NPP.
the formation of water level in the cleaning tank took only some minutes after saturation was
reached. The fuel behaviour calculations proved that the loss of fuel integrity in 5 hours after
the initiation of intermediate cooling mode was a result of fuel rod ballooning and burst [18].
The fuel rods could heat up above 800 ºC by that time and the high internal pressure in some
rods resulted in plastic deformation and burst. The calculation of zirconium oxidation pointed
out that the volume of produced hydrogen could be much larger, than the volume of the
The validity of safety analyses performed earlier was reviewed. The Russian firm Hydropress
performed the analysis of the operation with magnetite deposits burdened fuel assemblies [1]
for both normal and incidental conditions of the reactor units. These investigations have
shown that the deformations of the fuel assembly shrouds might be attained much easier if the
shroud temperature exceeds 355°C.
The Hydropress report suggested new operational limits: the relative mass flow of the
assemblies could not fall under 86% of the average value, because at lower mass flow rates,
the shroud temperatures might exceed the problematic temperature value of 355°C. For
controlling the mass flow limitations, the modification of the VERONA reactor core
monitoring system was also necessary. In addition, the Hydropress suggested to plan the
refuelling with extreme caution.
As a consequence of the above drafted events, the plant management decided to clean the
affected fuel assemblies, first time on the turn of the millennium. In the years 2000 and 2001,
the chemical cleaning of a total sum of 170 fuel assemblies was performed successfully in an
instrument designed by Siemens KWU, which was capable for housing 7 fuel assemblies
simultaneously [15]. In accordance with the preliminary expectations, this instrument
operated effectively. (From the viewpoint of the events discussed below, it is important to
mention that the cleaned fuel assemblies were removed from the core two years before the
cleaning process started and they had low residual heat. Furthermore, this equipment would
have been able to ensure the cooling of fuel assemblies of much higher thermal power. This
cleaning tank had inlet junction in the bottom and outlet junction on the top of the vessel. The
safety criteria specified by the Paks NPP experts were fulfilled for this equipment as it was
proved by the main constructor Hydropress.)
In November of 2002, the Paks NPP commissioned a reputed Western-European nuclear
company to design, construct and operate a new chemical cleaning equipment of larger
dimensions. With this new cleaning tank the operators were able to perform the chemical
cleaning of 30 fuel assemblies simultaneously with the same permanganate-oxalic-acid
method. The instrument arrived to Hungary in the beginning of 2003 and was placed into the
refuelling pit beside the reactor of Unit 2 in the Phase 1 of the Paks NPP (see Figure 2.2). The cleaning of the first batch of 30 fuel assemblies was started on 20th of March. Prior to the
incident, five batches were cleaned successfully. The 1st, 2nd, and 4th batches consisted of fuel
assemblies removed a few years earlier, but the 3rd and 5th batches contained fuel assemblies
with significant residual power (removed from the reactor on those days).

2.3.2 Plastic deformation of cladding and high temperature oxidation
Continuous temperature increase started in the tank, when the upper part of the fuel rods was
not cooled by water. The heat removal from the tank to the surrounding water was very low,
because the vessel was isolated by the double wall system. The temperature increase led to the
increase of pressure inside of the fuel rods. At 800-900 ºC the internal pressure could reach
30-40 bars. In this range of pressure and temperature plastic deformation of the cladding can
take place and the ballooning can lead to bursts and activity release from the fuel. It is very
probable that this type of fuel failure was responsible for the activity release measured by the
85Kr detectors. (Very long ballooned areas were found in the later visual inspection of the
fuel.) The first fuel rod ruptures were detected at 21:50, when the 85Kr measurement of the
AMDA system showed an unexpected jump in the signal (see Fig. 2.8) and a few minutes
later the noble gas detectors of the unit were also alerted.
the ECCS design basis for River Bend is substantially non-conservative in at least the
following aspects: 1) the cladding surface temperature (at some locations) at River Bend
Cycle 8 has been reported to have reached temperatures approaching 1200°F; therefore,
the starting temperature in the event of a LOCA would be almost 1200°F, not the
licensing basis for temperatures around 578°F; 2) the stored energy in the fuel with
cladding that had surface temperatures approaching 1200°F (at some locations) would be
substantially greater than that of fuel with cladding surface temperatures in the range of
578°F at the onset of a LOCA; 3) the amount of coolant in the vicinity of cladding with
heavy crud and oxide layers at the onset of a LOCA would be substantially less than if
the cladding were clean; 4) during blowdown and also during reflood the amount of
coolant flow past cladding with heavy crud and oxide layers would be substantially less
than the flow past clean cladding; 5) the increased quantity of the stored energy in the
fuel and the delay in the transfer of that stored energy to the coolant caused by a heavy
crud layer (mentioned by Klapproth in his letter to the NRC) would cause the cladding to
be subjected to extremely high temperatures for a substantially longer time duration than
the time duration used in the licensing basis, providing more time for heatup and
degradation of the fuel and cladding; 6) the severity of the fuel and cladding degradation
occurring in the event of a LOCA and its effect on obstructing coolant flow would be
substantially greater than those calculated by an ECCS design based on clean cladding; 7)
the increased quantity of the stored energy in the fuel and the delay in the transfer of that
stored energy to the coolant would increase the time until quench; 8) at the onset of a
LOCA, there would already be severe cladding degradation, massive oxidation and
absorption of hydrogen at some locations, which would contribute to a loss of cladding
ductility. (These same deficiencies in the design basis for the ECCS at River Bend-for
situations where cladding is heavily crudded and oxidized-also apply to the design basis
for the ECCS at other nuclear power plants.)
Because the ECCS design basis for River Bend is substantially non-conservative
when it comes to calculating the PCT for a postulated LOCA for conditions where there
are heavy crud and oxide layers on the cladding, there is reason to believe that with high
probability the PCT in the event of a LB LOCA at River Bend Cycle 8 would have
exceeded 2200°F (and that the plant would have violated other requirements of 10 C.F.R.

NRC paper on UO2 - Zry4 reactions
Effects of ID Oxide on Embrittlement After LOCA Scenario
Harold Scott and Ralph Meyer

Abstract
The NRC's cladding performance program at Argonne National Laboratory (ANL) is testing high-burnup cladding segments subjected to LOCA temperature transients. Tests have been conducted with segments from Limerick (9×9 Zircaloy-2) and H.B. Robinson (15×15 Zircaloy-4) reactors. Companion tests are conducted with unirradiated cladding to generate baseline data for comparison with the high-burnup fuel results.
Recent presentations by Ralph Meyer of NRC (RIC, March 2006, ANS-Reno, June 2006, and TopFuel, Spain, October 2006) have described embrittlement mechanisms that cause loss of ductility. The retention of post-quench ductility is the basis for NRC’s licensing criteria. This paper discusses mechanism Number 6, “Oxygen Pickup from the Cladding Inside Diameter.”
It would be desirable to examine those Halden IFA-650 tests that experience cladding temperatures >1000º C for evidence of ID oxygen diffusion. Metallography at ID locations far from the balloon could be examined in order to measure the depth of the alpha layer.
1. Introduction
During a loss-of-coolant accident (LOCA), the cladding temperature will rise and several phenomena will occur as illustrated in Fig. 1.
Fig. 1. Schematic cladding temperature during LOCA
At about the temperature that rupture occurs, the cladding metal will change from the alpha phase (HCP) to the beta phase (BCC). Above that temperature, oxidation on the surface of the metal and diffusion of oxygen into the metal become rapid. Increased concentrations of oxygen in the metal lead to loss of ductility or embrittlement.
Recent presentations by Ralph Meyer of NRC (RIC, March 2006 [1], ANS-Reno, June 2006 [2], and TopFuel-Spain, October 2006 [3]) have described embrittlement mechanisms that cause loss of ductility. They are :
· Beta-layer Embrittlement by Oxygen
· Beta-layer Thinning
· Localized Hydrogen-induced Embrittlement in the Balloon
· Hydrogen-enhanced Beta-layer Embrittlement by Oxygen
· Hydrogen-induced Embrittlement from Breakaway Oxidation
· Oxygen Pickup from the Cladding Inner Surface at Locations away from the Balloon
2. Oxygen Distribution
After going through a temperature transient such as illustrated in Fig. 1, the oxygen distribution in the cladding will be as shown in Fig. 2.
Fig. 2. Oxygen concentration in Zircaloy after oxidation in steam and cooling to room temperature.
Oxygen has diffused into the beta phase metal, and after a short time at high temperature the concentration in the beta phase has exceeded its solubility limit. The portion of the beta phase that is above this limit converts back to the alpha phase, which can hold more oxygen. At room temperature, the beta layer converts back to the alpha phase, but both the prior beta layer and the oxygen stabilized alpha layer are readily visible under the microscope as seen in Fig. 3.
Fig. 3. Unirradiated Zircaloy cladding after oxidation in steam at 1200̊ C for 600 seconds.
Notice from Fig. 2, that the oxygen concentration at the boundaries of the alpha layer are well defined at about 7% on the outside and 0.6% on the inside, depending somewhat on temperature.
3. Early Observations of ID Oxygen Pickup
In 1977, Hobbins and coworkers conducted power-cooling mismatch (PCM) tests in the Power Burst Facility in Idaho. [4] They observed an inside diameter (ID) oxide layer everywhere except in the neighborhood of a pellet chip, where the pellet and cladding were not in hard contact, as shown in Fig. 4.
Fig. 4. Cladding collapse into void in PBF test, showing presence of alpha-Zircaloy except in cladding adjacent to void. Cladding temperature about 1025̊ C. OD is at top of figure.
Hobbins observed that the thickness of the ID alpha layer was of comparable magnitude as the outside diameter (OD) alpha layer, which developed as a result of the reaction with steam in the test. Hobbins noted that oxygen diffusion into the Zircaloy was producing embrittlement, and that only where good contact between fuel and cladding was maintained was the reaction observed on the inside. Using embrittlement criteria, Hobbins concluded that a “two-sided reaction model is appropriate for these PCM tests in which almost as much oxygen is entering the cladding on the inside surface from the Zircaloy-UO2 reaction as is coming from the outside surface and the Zircaloy-H2O reaction.”
Two years later, Hofmann and Politis performed laboratory experiments at Karlsruhe to confirm Hobbins observations. [5] They put fresh UO2 pellets inside sealed unirradiated Zircaloy tubes and heated them in argon under various pressures. These investigators found a reaction between the Zircaloy cladding and the UO2 fuel pellet when there was sufficient pressure to cause solid contact, and they noted that oxygen from the UO2 also diffuses into the Zircaloy to form the alpha phase as shown in Fig. 5.
Fig. 5. UO2 -Zircaloy interaction after 30 minutes at 1200̊ C under an argon pressure of 10 bars.
Hofmann and Politis compared their observed alpha layer with that in steam oxidation experiments performed in the same laboratory by Leistikow and Schanz and concluded “that the thickness of reaction zones formed in the Zircaloy- UO2 reaction experiments and the Zircaloy/steam oxidation experiments is nearly identical.”
4. Recent Observations of ID Oxygen Pickup
Although most of the samples used in the Argonne program have been oxidized on two sides, a short series of 1-sided tests were run with irradiated rods from the H. B. Robinson PWR having a burnup of about 65 GWd/t. These defueled specimens were oxidized at 1200̊ C with steam flowing over the outside and argon flowing through the inside of the tube segment. Microscopy was done on two of these specimens, and both show a substantial ID alpha layer. One sample has a measured ID alpha layer of 36±5 microns compared with an OD alpha layer of 42±4 microns, and this specimen is shown in Fig. 6.
Fig. 6. Inner surface of 64 GWd/t H. B. Robinson PWR cladding after 1-sided oxidation at 1200̊ C, showing well developed alpha layer.
The other specimen had a measured ID alpha layer of 35±8 microns compared with an OD alpha layer of 58±7 microns. It is presumed that this oxygen came from the ZrO2 bonding layer on the ID of the cladding. It can be noted that these specimens had been etched to remove all traces of UO2 , which was attached to the other side of the bonding layer. Thus the somewhat smaller thickness of the ID alpha layer compared with the OD layer is probably the result of removing much of the ID oxygen source, leaving a limited amount in the bonding layer that was totally consumed.
A number of 1-sided tests were also run with irradiated rods from the Limerick BWR having a burnup of about 55 GWd/t. These specimens had also been etched to remove all traces of UO2, which was attached to the other side of the bonding layer. The specimens had a bonding layer that was not uniform around the cladding ID and no ID alpha layer was seen after holding at 1200̊ C for about 300 seconds. However, calculations show that oxygen from an alpha layer would have continued to diffuse into the beta layer until its oxygen content were too low to stabilize the alpha phase.
Four integral tests were run with the irradiated Limerick rods, and three of them were run at high temperature in steam (300 seconds at 1200̊ C). Steam was present on the ID only in the balloon region. Away from the balloon, only one local region in one of the tests (ICL#2) exhibited an ID alpha layer as shown in Fig. 7. Although not conclusive, these results are consistent with (a) incomplete bonding in BWR fuel at ~55 GWd/t, (b) formation of an alpha layer only in the bonded regions, and (c) diffusion of oxygen from the bond layer resulting in both reduction of the bond layer and disappearance of the alpha layer.
Fig. 7. Evidence of an ID alpha layer at location B and absence of such a layer at location A in a fuel rod specimen (including fuel) that was held at 1200̊ C for 300 seconds in an integral LOCA test.
Bonding occurs earlier in PWR fuel than in BWR fuel because the higher system pressure in PWRs results in more cladding creepdown. Bonding between the fuel and the cladding eventually occurs in BWRs as well. From ANL characterization work performed for Limerick BWR high-burnup (55-57 GWd/MTU) fuel, Surry low-burnup (36 GWd/MTU) fuel, TMI-1 PWR intermediate-burnup (48 GWd/MTU), and H. B. Robinson PWR high-burnup (63-67 GWd/MTU) fuel, it appears that bonding (and hence ID oxygen ingress during a LOCA) would begin at ≈30 GWd/t in PWR fuel and be complete around ≈50 GWd/t, whereas it would not begin in BWRs until ≈40-50 GWd/t.
5. Conclusion and Recommendation
It is clear that if oxygen sources are present on the OD and the ID of the cladding, oxygen will diffuse into the metal equally from both sides as in a multi-layer diffusion “couple” such as illustrated in Fig. 8.
Fig. 8. multi-layer diffusion “couple”
It is also clear that bonding between the UO2 fuel and the zirconium-alloy cladding can provide the good contact that is needed. What is not clear are the conditions under which this bonding is sufficiently complete to promote ID oxygen diffusion.
It would be very valuable if microscopy could be done on IFA-650 specimens at locations away from the balloon to compare the OD alpha layer with any ID alpha layer that might be present.

UHI: In 1984 INPO told NRC's AEOD that it had no concern with stored gases.
And next is the abstract of the ORNL report.
ORNL found that if Nuclear Power Plants complied with "... well-known and established ..." methods, the nuclear power plants would have no problems in this arena. ORNL apparently complied with AEOD specifications in producing its report that was completed in April 1985 although INPO was invited to review a draft on November 9, 1964. AEOD's specifications to ORNL should have included UHI accumulators and ECCS accumulators. However, such a specification was beyond the experience. insight and talent at AEOD.
I've checked the NRC's Public Document Room and I find no evidence that EPRI's NSAC was invited to review the ORNL document even though there was a Memorandum of Understanding that such documents would be discussed with NSAC. Of course, even if NSAC would have been invited to look at the ORNL report, it is unlikely that I would have had a shot at it.

Subject: Re: Please send me INPO 76-84
The NRC claims that INPO has met the requirements for showing that INPO 76-84 is covered by FOIA Exemption 4:
"Trade secrets and commercial or financial information obtained from a person that are privileged or confidential."
It is highly unlikely that INPO 76-84 has one bit of Trade secrets and commercial or financial information that are privileged or confidential.
However, for the time being, let me refine my request. In this refined request, I am seeking public disclosure of those aspects of INPO 76-84 that discuss the Salem lightning strike of June 8, 1980.
I reported this event as a significant event on August 12, 1980, when I was with NSAC. Within hours of my report, INPO objected to my submittal. I insisted that my submittal should stand. A long time later, March 11, 1982, I found out that NSAC had indeed buried my report.
I was way ahead of my time. It was not until 1985 that NRC issued the following:
November 5, 1985
Information Notice No. 85-86:
LIGHTNING STRIKES AT NUCLEAR POWER GENERATING STATION
Description of Circumstances: A number of plant trips and instrumentation problems attributable to lightning have occurred over the past 6 years. Since solid state circuitry designs are being increasingly employed in safety related systems, the impact of lightning induced line surges on those circuits is emphasized in this notice. Descriptions of several of the more significant events are presented below. Events involving lightning strikes of switchyards and the consequential impact on power distribution systems are not covered by this notice. However, INPO SER 76-84 covers this latter subject as well as summarizing earlier INPO documents dealing with lightning strikes at nuclearpower plants.
Note the public reference to INPO SER 76-84. Very likely this INPO SER 76-84 includes the Salem lightning strike of June 8, 1980.
So, for the time being, what I am asking for is the coverage of the Salem lightning strike of June 8, 1980 that is in INPO SER 76-84.
In its final response to my FOIA, the NRC told me that under its agreement with INPO, described as a Memorandum of Understanding dated December 10, 2007, the NRC is required to protect INPO documents from unauthorized disclosure when they contain proprietary information.
I have read the Memorandum of Agreement dated December 10, 2007, and I find that the NRC is not legally required to do anything: I read on page 1;
This Memorandum is not intended to be an enforceable agreement or contract on either party ... Since this Memorandum is not legally binding, the Commission may depart from its terms whenever it deems it necessary or appropriate to do so ...
Well, it is highly unlikely that INPO SER 76-84 contains any proprietary information regarding the lightning strike at Salem on June 8, 1980. Indeed, I doubt if INPO SER 76-84 has any information that is in greater depth than Salem LER NO. 50-272/80-031.
So, for the time being, I would like to see the aspects of INPO 76-84 that describe the events at Salem on June 8, 1980.
I have also provided the attachment, Memorandum of Agreement, December 10, 2007, that has the text of this forwarded e-mail.

Petition for Rulemaking
NRC must augment its regulations in order to halt the widespread misapplication of 10 CFR 50.59. For example, the process, ultrasonic fuel cleaning, has been effectively licensed at several nuclear power plants in the United States of America via licensee application of !0 CFR 50.59. Several sites have installed and operated the equipment and the sites have performed reviews under 50.59. The NRC has thus effectively licensed ultrasonic fuel cleaning via 50.59 as its site inspectors have ruled at several sites that the 50.59 documents are within the purview of the site license and that they have been satisfactorily prepared. It is also significant that NRC approval under 50.59 is an after-the-fact approval; the equipment may be installed and operated without the awareness of the NRC or its public.
This petitioner is concerned that ultrasonic fuel cleaning has been deployed at several sites without an in-depth review and acceptance by specialists at the NRC. Ultrasonic fuel cleaning is an involved process that is beyond the licensed capabilities of the sites to review and accept under 10 CFR 50.59. It is also likely that modifications of ultrasonic fuel cleaning will proceed without the necessary NRC oversight. This petitioner is not listing all of the potential areas of modification; however measures to speed up the process in the areas of fuel handling, chemical addition, waste disposal, and other changes appear likely within the present mode of licensing ultrasonic fuel cleaning.
It appears that the Electric Power Research Institute (EPRI); the developer, patent assignee, and promoter of ultrasonic fuel cleaning, has succeeded in having its process deployed at several nuclear power plants as the sites have applied the 50.59 process. EPRI has promoted its ultrasonic fuel cleaning and has made its consulting services available to the sites as it has bypassed review of the ultrasonic fuel cleaning by the Office of Nuclear Reactor Regulation, the Office of New Reactors, the Office of Nuclear Regulatory Research and the ACRS.

GE consultants squealed and Rickover's offspring took over everywhere.
INPO, operating in its standard mode of indoctrination, talked everywhere and ultimately a lot of good men got stabbed and the nuke business has been a good place to stay away from ever since (unless you have an aptitude for playing along with the games of indoctrination). Anyway, the good men were forced out of the scene after they “confessed.” The reactor plant operators wound up in uniforms that highlighted their rank. And, the press had a field day as they made good dough by catering to Rickover’s offspring.
So, here is the New York Times in action over 20 years ago when they were already adept at producing fiction. I’ve put paragraphs in bold that refer to INPO. Otherwise, this copy is unadulterated.
The Peach Bottom Syndrome

By MATTHEW L. WALD
Published: March 27, 1988
THEY came to work in jeans and T-shirts, and passed the hours with magazines, video games and rubber band fights. Often, they took turns sleeping, and sometimes everyone on the shift was dozing.
The scene was not an obscure back office operation, but the control room of the Peach Bottom Atomic Power Station here, 65 miles west of Philadelphia and 45 miles down the Susquehanna River from Three Mile Island.
When the sleeping on the night and weekend shifts was finally discovered, the Nuclear Regulatory Commission shut Peach Bottom, the first time a nuclear power plant had been closed by the agency for a non-mechanical reason.
That was a year ago, on March 31, 1987, and the intervening months have been tough ones for the four utilities that own the plant. Led by the Philadelphia Electric Company and the Newark-based Public Service Electric and Gas Company, which each hold a 42.5 percent stake, the four have been spending about $14 million a month for replacement power, most of the cost borne by stockholders.
Philadelphia Electric, which was already facing a financial squeeze from another nuclear plant that it is building, has taken other, even harder lumps as Peach Bottom's operator: its president and chairman both announced their early retirement this year following a scathing report by an industry group. The group, the Institute of Nuclear Power Operations, called Peach Bottom ''an embarrassment to the industry and to the nation,'' and said the fault lay in the very culture of the company and how it was managed.
For the industry, however, the episode is not a simple embarrassment but rather the most dramatic sign to date of a basic shift in safety concerns since the accident at Three Mile Island nearly a decade ago.
Where once regulators focused on machinery and backup systems to insure ''fail-safe'' operations, they have now come to stress the importance of the human operator in anticipating problems and solving them before they become disruptive.
NOW the message seems to be that faulty operators will not be tolerated any more than faulty equipment, and that top management will be held more accountable when there is a human problem.
The shutdown of Peach Bottom was ''a wakeup call for the nuclear industry,'' Senator John Heinz, a Pennsylvania Republican, said at the time.
As the first anniversary of the shutdown nears, questions remain about just how responsible upper-level management was for fostering an atmosphere in which sleeping at the nuclear switch became possible. Most regulators and critics within the industry say that top management should have known of the problems and acted to cure them, and that lower-level management did know and did not care.
They also note that the problems were not confined to control room personnel. Four Philadelphia Electric workers and two contract employees elsewhere in the plant were indicted last fall for drug dealing. Two were acquitted and the others were convicted or pleaded guilty. Just last week, Philadelphia Electric announced it had discharged or suspended 17 employees who the company said had been using drugs, including the four who had been indicted.
Now the industry is watching closely as Philadelphia Electric, after floundering for much of 1987, tries to re-engineer its culture and convince Government officials that the management problems have been solved and that Peach Bottom 2 and 3, the two reactors at the plant, should start operating again.
PHILADELPHIA ELECTRIC, known as Peco, has not been the only utility with troubles in its control room. The Chicago-based Commonwealth Edison Company was fined in 1980 when two of its operators were caught sleeping on duty in its Dresden plant near Morris, Ill. The following year, the Florida Power and Light Company was fined after its operators left a control room unsupervised while a reactor was running at full power. And last August, four and a half months after Peach Bottom was shut down, an operator was removed by the Pennsylvania Power and Light Company from its Susquehanna plant for sleeping on the job. Even the General Public Utilities Corporation, owner of Three Mile Island, discharged a shift supervisor last November who had repeatedly slept on duty.
But these incidents apparently have been isolated. At Peach Bottom, for at least five months, they were the norm. The lax environment here was ironic in light of the plant's special role in the industry's development. Peach Bottom 1, which opened in 1966 and is now retired, was one of the first commercial reactors in the United States, making Philadelphia Electric one of the nation's most experienced nuclear operators and a pioneer in developing safety rules.
A variety of reasons have been offered to explain how the staff's alertness in Peach Bottom's pioneer days turned into the kind of dangerous overconfidence that put operators to sleep. Management and the Nuclear Regulatory Commission were more concerned with the problems starting up the company's new Limerick plant, 50 miles to the northeast, than with changes going on at Peach Bottom, investigators say. In addition, Limerick drew personnel away from Peach Bottom, creating a shortage of operators and a need for excessive overtime.
But most of all, according to the N.R.C. and the Atlanta-based Institute of Nuclear Power Operations, there was a break in the chain of command that kept critical information from going to headquarters, and no one there seemed to notice.
Indeed, the problem with the sleeping technicians was finally brought to light by outsiders, six General Electric engineers with frequent access to the control room, who went to the N.R.C. with their complaints after two levels of Philadelphia Electric executives at the plant turned deaf ears.
After the shutdown, the company's top executives found flaws far down the chain of command. Referring to tighter safety rules implemented after the Three Mile Island accident and other mishaps, Philadelphia Electric's departing chairman and chief executive, James Lee Everett 3d, said, ''The attitude of some of our operating force to enthusiastically receive and endorse these new requirements has been less than the best.''
But in its report, given to Mr. Everett in January, the Institute of Nuclear Power Operations implied that the executives at the top should quit, referring to ''grossly unprofessional behavior by a wide range of shift personnel'' that ''reflects a major breakdown in the management of a nuclear facility.'' The institute said that both Mr. Everett, 61 years old, and the company's president, John H. Austin Jr., 59, had failed to understand basic aspects of the problem.
The Nuclear Regulatory Commission also found fault at the top, and gave Mr. Austin and Mr. Everett a public dressing-down of a kind seldom seen in the industry. At a commission hearing in Washington last Sept. 14, Lando W. Zech, the N.R.C.'s chairman, argued that problems with corporate management were as serious as those at the plant.
AT the hearing, Mr. Everett and Mr. Austin presented a 100-page plan for re-starting the plant. The plan noted that 12 of the 36 operators and supervisors in place at the time of the shutdown had been assigned to other jobs or had retired and the rest were enrolled in an extensive retraining program. Many new people with strong technical backgrounds were being trained as replacements, it pointed out. And it listed 300 separate hardware improvements in the works, and said it was well on its way to a complete change in the corporate culture that had been so heavily criticized.
It was apparently not enough for Mr. Zech, a retired admiral who was the chief of technical training in the Navy for two years. ''You've told us a lot of things,'' the chairman said. ''You've got to get to the next layer. What does it mean? What are your real commitments to excellence?''
Many in the industry thought Mr. Zech simply wanted some heads to roll. They finally did in February, when Mr. Austin announced his retirement. Early this month, Mr. Everett said he would step down, too, effective April 13. Joseph F. Paquette Jr., 53, a 30-year man at Philadelphia Electric who spent the last two years at the Consumers Power Company in Michigan, was brought back to replace Mr. Austin and will also be given Mr. Everett's titles.
In the utility industry, where succession is usually planned years in advance, and at Philadelphia Electric, where posters and in-house publications refer to ''The Peco Family,'' the changes of the past year amount to a painful revolution. But they may pay off soon.
''For the first time we're starting to hear realistic estimates of how long it's going to take'' to reopen the plant, William Russell, the N.R.C. administrator for the region covering Peach Bottom, said last week. ''They're no longer talking about reopening this summer. They're talking about the first of the year, and it's positive that they realize what they have ahead of them.''
The company is expected to disclose its latest schedule to reopen the plant on April 8.
WHAT is happening now at Peach Bottom is something of a nuclear novelty. Where the documents for restarting a reactor might once have spoken of neutron fluxes and rod insertion times, they now talk about beliefs, values, missions and vision. What Philadelphia Electric offers now is not apology, but anthropology.
Culture is the buzzword. The N.R.C. and plant management have taken to using that term to describe the shared attitudes of operators, their supervisors, their supervisors' supervisors and so on, all the way up the chain of command to the chairman.
Corbin A. McNeill Jr., a former chief of the Navy's Nuclear Power School and Philadelphia Electric's new senior vice president for nuclear operations, one of seven new senior executives brought in to clean up the company, speaks of giving the operators a new culture. The company's plan for restarting the plant even lists as a basic cause of its problems that ''the station culture, which had its roots in fossil and pre-Three Mile Island operations, had not adapted to changing nuclear requirements.''
Those requirements have evolved over the years since Philadelphia Electric ordered the reactor from the manufacturer, the General Electric Company, in November 1958. The N.R.C., with its stricter views, replaced the Atomic Energy Commission in 1975, and at plants around the country the fires, ruptures, leaks, procedural errors, instrument failures and other mishaps over the years gave hints of the pitfalls of the new technology.
With a growing appreciation of what can go wrong, what it can cost to fix and how much radiation exposure is potentially involved, the culture that the N.R.C. is trying to foster takes a much more aggressive stance on safety. For example, at first the N.R.C. sought assurances from plants that the automatic shutdown systems would stop a reactor if any of 100 pieces of equipment malfunctioned. Now, each such shutdown is considered a black mark, to be avoided by preventive maintenance or anticipation of problems before they occur.
THERE was change here, too, at the foot of Atom Road: Peach Bottom 1, a small 40-megawatt reactor, was retired in 1974 and replaced with Units 2 and 3, twin reactors each producing 1,035-megawatts, enough power to light all of Philadelphia.
But memories of the early days were still strong. That was a time before each control room contained a cross-indexed looseleaf notebook three feet thick to provide the operators with a procedure for every eventuality. ''We invented some of these procedures,'' said Raymond R. Betz, an operations support superintendent who was one of Unit 1's first reactor operators.
Long-time employees like Mr. Betz, who is 54 and has been at Peach Bottom for 25 years, view themselves as pioneers and take pride in that. But for some workers, according to recent studies, the pioneer mentality turned to complacency.
Another problem was Peach Bottom's remoteness from Philadelphia. About four miles north of the Mason-Dixon line, in a bucolic, agrarian setting, Peach Bottom was not much on the minds of the corporate executives, and vice versa.
Headquarters was preoccupied with other problems, notably those at Limerick, another twin-reactor project for which ground was broken in 1967. After extensive cost overruns, the state Public Utilities Commission in Harrisburg told the company that $369 million of the overrun was an imprudent expense, incurred because of mismanagement, and that it would not be allowed to recover that portion from ratepayers.
Limerick's Unit 1 is now running and the ratepayer ruling is under appeal, but Unit 2, almost 90 percent complete, has had an uncertain course. Rapid shifts in construction costs and a start-stop pattern in the rate of growth for demand for power had Philadelphia Electric begin work on Limerick 2, suspend it and then start again. In addition, environmentalists have blocked construction of a pumping station along the Delaware River that is needed for cooling water if the Limerick reactors are to run at full power in the summer.
IN the Peco family, Peach Bottom had become a quietly troubled adolescent that was being neglected in favor of a seriously ill younger sibling. Making things worse, Peach Bottom was giving its sibling transfusions, sending some of its most talented and ambitious personnel to Limerick, where the possibilities for promotion were greater.
Operations at Peach Bottom began to suffer. ''We should have changed management at the plant a lot earlier than we did,'' said Mr. Everett in an interview last week. ''We should have recognized the kind of attitude problems we had.''
The bombshell did not hit until last March, but there were telling signs earlier. The Institute of Nuclear Power Operations had told the company in December 1984 that it found ''clear evidence of declining performance'' by station personnel and in January 1986 that ''standards of performance at the station are unacceptably low.''
Presaging events to come, at 6:05 A.M. on June 10, 1985, an N.R.C. inspector entered the control room at Peach Bottom and spotted a reactor operator with his head tilted on the back of the chair, his eyes closed, according to an agency report. After much discussion with company officials, the N.R.C. decided that it would not pursue disciplinary action because the inspector was not able to prove that the operator was sleeping.
Another indication of trouble was fines by the N.R.C. on six separate occasions since 1981 for a variety of rule infractions. But the signs apparently were not being picked up at corporate headquarters or at the plant, where plaques hung on the walls to mark reliability and electric production records in past years.
''We thought we were doing a great job,'' said one of the reactor operators, John S. Deni. ''One year we set an all-time record for what a generator could do.''
Mr. Deni was one of two operators made available by the company for an interview. He is one of the 24 operators undergoing lengthy psychological screening and retraining.
While Philadelphia Electric concluded that ''essentially all'' of the control room personnel had slept on duty or had been inattentive, none were discharged. Those who are being kept on as operators have been through an ''enforcement conference'' with the staff of the N.R.C., a quasijudicial procedure. They face a possible loss of license, fine or reprimand, but a decision on sanctions has been postponed, presumably because it will be linked to the decision on reopening the plant itself. If the operators are suspended, it could delay the plant opening beyond the end of the year.
Philadelphia Electric executives, asked why the operators were not simply fired, pointed out that they are the cream of the station's staff, each trained at a cost of tens of thousands of dollars over many years. In addition, licenses are plant-specific; that is, operators from Limerick or other reactors could not be brought in to run the Peach Bottom plant without first being extensively retrained.
And a nuclear reactor is like a jet liner that never lands. Even when all the fuel is removed from the reactor vessel, as has been done at Peach Bottom 3 for repair work, licensed operators must still be present in the control room 24 hours a day, monitoring equipment that prevents the release of radiation.
Besides, the new executives at Philadelphia Electric say, sleeping on the job is not something for which the operators should take all the blame. ''If everybody's been driving 60 in a 55 mile per hour zone, you haven't explained to them what the speed limit really is,'' said Dickson M. Smith, a retired rear admiral and former senior military staff assistant to Adm. Hyman G. Rickover, who was hired late last year to go to Peach Bottom as plant manager and then promoted to vice president. ''Right or wrong, it was something that was acceptable,'' said Mr. Smith, who is still based at the plant.
Mr. Deni described a hunkered-down mentality in the control room in the months before the shutdown. Part of the problem, he and others said, was a shortage of personnel. ''We were down to maybe 10 guys to cover the two units, and we circled the wagons,'' he said.
If someone fell asleep, Mr. Deni said, ''it seemed natural to cover for each other.'' He added: ''We thought we had a handle on things, and it was hard for anybody to give us any input.''
The report by the Institute of Nuclear Power Operations also hints at poor relations between the reactor operators and employees of G.E. This may eventually have spelled the operators' downfall.
THE other operator provided by the company for an interview, J. Michael Weaver, who has since been promoted to shift supervisor, pointed out that even if the overtime was excessive, it was attractive. An operator who worked eight-hour shifts on two consecutive scheduled days off would earn time-and-a-half for the first shift and double-time for the second. Reactor operators earn about $20 an hour. In that setting, sleeping became the norm, and a very lucrative one.
The remedy offered by the company has concentrated on group dynamics and a retraining course, ''People, the Foundation of Excellence,'' that was developed by the Management Analysis Company, a consulting firm based in San Diego with wide experience in the nuclear field.
The operators seem to be developing a new self-image. Eschewing jeans and T-shirts, they are instead wearing - voluntarily, they insist - gray slacks and color-coded shirts: light gray for reactor operators, blue for senior reactor operators and white for shift supervisors. It enhances their authority, they say.
The entrance to the plant is dominated by a banner promoting ''The Power of Excellence,'' a slogan selected from employee nominations by a jury of employees. In an effort to make employees feel more a part of the operation, Mr. Smith has installed suggestion boxes, which have drawn more than 1,100 responses. Some were trivial and quite a few were colorful, but only two, according to papers filed with the N.R.C., were outright hate mail.
Workers at the plant say that much has changed, often citing the sheer volume of personnel transfers that have left them with new supervisors and upper-level managers. They also talk about a different mood. ''My job has changed,'' said Michael R. Smith, an instrumentation and control engineer who has been here for two years. ''It used to be day to day, to get through the day and get the job done. Now it's to streamline efficiency, to improve quality.''
Managers are changing their style, too, according to the company. The Philadelphia Electric plan for re-starting the plant refers to several new strategies, including ''management by walking around.''
HOW much attitudes have really changed among the 3,000 people at the plant - more than 1,000 are Philadelphia Electric employees and the rest work for contractors - is difficult to tell, management concedes. Mr. McNeill, the new head of nuclear operations, drew an analogy to the change in attitudes that came when racial segregation ended in schools. ''You can't change everybody's attitude but you can change behavior,'' he said.
And old procedures are also giving way. Formerly, there was little regular maintenance work reserved for the night shift. Now some maintenance activity is deliberately scheduled for the ''back shift'' to keep the operators occupied.
The company is also trying to relieve the problems of shift work itself. ''If you're a shift worker at a generating station, you're a shift worker until you retire or die,'' said James Lange, president of the Independent Group Association, an organization that represents employees in negotiations with management but does not have collective bargaining status.
Now, however, Philadelphia Electric, according to its plan for restarting the reactors, is providing some shift personnel with ''alternative career paths.''
Perhaps more important, the company has cleaned house on a grand scale. Of the 21 highest-ranking officials in the company, a third got their jobs this year. Essentially all the management at Peach Bottom was reassigned, beginning with the shift superintendents, the level at which Philadelphia Electric says the problem was allowed to fester.
It was a dead-end job, investigators concluded later, and the men in it were therefore unmotivated. According to Mr. McNeill, they were ''put in a position where they didn't consider themselves true management personnel, yet they knew they were different from the operators.''
New management says the company will not rush the process of re-opening the plant, but that Peach Bottom has turned the corner. Yet after all the departures, there is still a touch of defensiveness.
Mr. Lange, of the employees' association, described the going-away party for Mr. Austin, the retiring president, as ''like a wake,'' with hundreds of people lined up to shake his hand. ''There's no reason either of them should feel disgraced,'' he said of Mr. Austin and Mr. Everett.
BUT they left amid criticism that even after the shutdown, they had not recognized their role in the problems. For example, Zack T. Pate, the president of the Institute of Nuclear Power Operations, argues that even months after the shutdown, the two men were insisting that the problem was at Peach Bottom and not in headquarters' response.
In a letter to the chairman of a special committee of Philadelphia Electric's board, Mr. Pate described a meeting with Mr. Austin last Sept. 10. According to Mr. Pate, Mr. Austin said that Management Analysis, the consulting firm, had concluded ''that the problems were unique to Peach Bottom, and were not rooted in the corporate organization.''
But the next day, Mr. Pate related, the president of Management Analysis telephoned and said that ''he was concerned because the problems at Peach Bottom had their roots in the Peco corporate organization, and that management corrective actions were aimed principally at the plant.''
In his letter, Mr. Pate wrote, ''This is another example of Peco senior management's inability or refusal to face up to and deal with problems in their corporate nuclear program.''
Mr. Everett, in the interview last week, said that Mr. Pate may have misunderstood what Mr. Austin was telling him. Mr. Austin declined requests for an interview.
Mr. Everett said that ''our priorities were, let's fix what's wrong at the plant, then sit back and really do a deep study of corporate management, and try to organize to go forward in the future. If we had been smarter, in hindsight, we would have put that reorganization up front, at least while we were fixing up the plant.''
But Mr. Everett said that he did not feel that he was hounded from office, and that he was leaving the company in good shape, with enough generating capacity on hand or near completion to meet its needs until the mid-90's. ''This company is positioned extremely well,'' he said.
The new chairman, Mr. Paquette, has acknowledged that his predecessors did not properly define the problem, but he stops short of blaming them. ''It doesn't matter whether they were guilty or weren't guilty,'' he said. ''We're starting fresh.''
''Everyone in the direct line from the former chairman, the former president and all the people in charge of the nuclear division at headquarters are no longer in those positions,'' he said. ''That's a very, very telling, dramatic point to make.'' THE FINES Civil penalties by Nuclear Regulatory Commission against Peach Bottom 2 and 3.
Two violations that would have allowed radiation to spread in case of accident, one violation that interfered with a reactor automatic shut-down system, and multiple violations of radiation protection procedures.
A violation that would have increased the spread of radiation in an accident, and failure to re-set valves properly on a test line.
Five violations of rules set in the plant's operating license.
Radiation protection violations.
Violations of operating procedures and poor management supervision involving four licensed reactor operators.
Firing of a contractor's employee who complained about radiation exposure.
