So, the above note states "... all cognizant NRR/DSS staff, who would be qualified to serve on the working group for PRM-50-93/95, are otherwise occupied in various capacities responding to the recent events in Japan." Now, there is no reference in the NRC's review of Fukushima that is dated July 12, 2011, that anyone investigated the temperature of the zirconium alloy at which hydrogen formation began. Clearly, the work on PRM-50-93/95 should have been completed a long time ago.

The new move of NRC to hide the real issue forces me to re-post here:
As I wrote in the comment to US NRC http://pbadupws.nrc.gov/docs/ML1033/ML103340250.pdf
: „It is a much overdue duty of NRC and IAEA to evaluate the evidence provided by the TMI-2 accident, Chernobyl-4 accident, Paks-2 incident, and related experiments. Evaluating this evidence, one can see that the ignition of the zirconium fire in the steam occurs at a local temperature of the fuel cladding of around 1000-1200'C, [[and that a self-feeding with steam due to the precipitation of eroded fuel pellets and zirconia reaction product from the hydrogen stream into the water pool, causes intense evaporation.]] There are insignificant differences in the progression of the firestorms that occurred in the TMI-2 reactor severe accident, Paks washing vessel incident, and Chernobyl-4 reactor accident; the later defined only by the amount of zirconium available for the reaction. At the mean time, there are significant similarities in the processes leading to the ignition of the firestorm. In all three of the compared cases, it took several hours of ill-fated actions or in-actions of the operators to cause the ignition condition. Also, there are similarities in the end result of the firestorm; namely, that the extent of the fuel damage is much less than it was predicted from any other severe fuel damage causing scenarios, introduced for explanations. Therefore the fraction of released fission products is significantly less than was anticipated from the fuel melting or a so called "steam explosion" scenario. Also, the fiery steam-zirconium reaction results in a much higher than anticipated (from any other scenarios) rate of Hydrogen production, which in turn requires a review of containment designs.” I hope the gentlemen will recognize the same process in the Fukushima Daiichi 1-3 reactors as the leading, key process. I hope we will have a thorough investigation of the fiery steam-zirconium reaction and there will be issued a call for shutting down the 11 still operating Chernobyl type (RBMK) reactors in Russia
Mr Leyse,
You are so quick to criticize the NRC when they don't act precisely the way you want them to. Now that they have released the first of its responses to the rulemakings you support, why have you not even acknowledged this with a statement that they have done so? It may take you more time to digest their response and come up with an appropriate response of your own, but if you are going to criticize them for not acting quickly enough, you should, at least, acknowledge when they finally do, and apologize if appropriate. If you expect people to take you seriously, you should not limit your posts to only complaints and conspiracy theories. Otherwise, your posts simply become the inane rantings of an old man who has a hidden agenda and axe to grind. Not the posts of someone with a legitimate issue to be raised.
I would highly suggest you read Dale Carnegie's book, "How to Win Friends and Influence People".
Meebo Gleebo - or whoever is hiding under this name...
The recent action of NRC is a non-action, delay. I wonder how many more severe accidents in the form of zirconium fire in the steam and subsequent Hydrogen explosions have to occur for NRC to take this process into consideration.
It is clear that in connection to Fukushima Daiichi the sweeping under the rug started as well.
