Hardened vents and filtered vents: July report soon?

On February 27, 2012, NRC Chairman Jaczko issued the following:

http://www.nrc.gov/reading-rm/doc-collections/commission/cvr/2012/2012-0025vtr-gbj.pdf

In the fourth paragraph on page 2 of 3 of the above reference we read "... important that the Commission make a decision on the topic of filtered vents this summer ... ."

Now that the NRC has a new Chairman, it is likely that the Jaczko-inspired focus on filtered vents will "go away."
A policy paper from the staff was expected from the staff in July 2012 according to the above document.

And here is a notice of a meeting of July 12, 2012 that I missed:

Here are slides from the July 12, 2012, meeting.  Fretz of NRC e-mailed these July 24, 2012:

And here is the order for hardened vents. March 12, 2012:

And here is the ACRS Fukushima subcommittee meeting of May 28, 2012:

http://pbadupws.nrc.gov/docs/ML1218/ML121850039.pdf

From page 117 of 292:

MR. LEYSE:  Yes, this is Bob Leyse and I'll be damned brief because I have said this before.
          In terms of a holistic approach, the 2200 degree Fahrenheit criterion that all plants are licensed under, for example, Palo Verde, the Baker-Just equation is based on specimens, zircaloy specimens, that you can handle, walk around in your pocket as pocket change.
          In contrast to that, NRC is funding a huge program at Sandia in which bundles of fuel rods, 49-rod bundles, and earlier I guess, some BWR bundles, are tested in air only.  For a fraction of the cost of that stuff, you could do the kind of tests that would show in terms of U. S. data that the 2200-Fahrenheit limit is too high.

PRM-50-93 Quick access to the NRC delays

Here is PRM-50-93:

http://pbadupws.nrc.gov/docs/ML0932/ML093290250.pdf

Submitted November 17, 2009
Docketed November 23, 2009

Many delays characterise the NRC review of this. 

Here is a delay that was described by NRC over a year ago in an internal e-mail dated March 23, 2011. 

http://pbadupws.nrc.gov/docs/ML1121/ML11216A081.pdf 

Go to page 371 of 899, and the fastest way to get there is via a word search on PRM.  The e-mail discloses that "... all qualified NRR/DSS staff who would be qualified to serve on the working group for PRM-50-93/95 are otherwise occupied ... recent events in Japan."
