I do not. They probably said, but it went in one ear and out the other. It may be listed in the minutes if they issue a set. Dana

Thx, Dana:

Do you know who from NRC call in?

Subject: Budnitz Garwin Per show

NOAA has completed apparently a detailed analysis of the tsunami showing among other things that peak wave heights at some points in Japan were as much as 37 meters!

It will be of interest to see the NOAA analysis once it is published. (Garwin is of course suspicious of the analysis).

TEPCO is confident that water level in spent fuel pool is well above the top of the active fuel -6 meters – Garwin is dubious.

Per continues his work to do a shaker table test on water sloshing – despite all expert assurances water did not slosh out and no one really cares now.

BNL continues to work on the Markov model that I don’t even begin to understand – Budnitz has done similar things in the past. Garwin is unpersuaded.

They are still looking at phosphate for pH control. They recognize the issue of precipitation. They may not recognize that phosphate will enhance uranium dioxide dissolution in oxygenated systems.

Per wants them to handle the contaminated water. Garwin wants to know why we are not getting more definitive information.

In other words, you did not miss a thing! Dana
