Fwd: Confirmation of telephone conversation Ed, Here is Mr. Webster's e-mail confirming our conversation. My original e-mail documenting the call went out about 4:00 pm on the afternoon of 9 November.

Mr. Fuhrmeister, Thank you for taking my call. I wish to confirm that I believe the preliminary notification that bears your name is inadequate to assess whether the Oyster Creek Nuclear Power Plant has sufficient justification to restart, in part because it fails to assess what area of the drywell shell in each bay in the sand bed region is thinner than 0.736 inches. As I explained, the one square foot acceptance criterion derives from modeling conducted by GE, which showed that the drywell would meet code if the shell had a uniform thickness of 0.736 inches with one square foot of area in each bay at thickness 0.536 inches.
In order to show that the stresses in the drywell are bounded by the GE modeling, the applicant must at least show that the total area per bay that is thinner than 0.736 inches is less than 1 square foot in area.
Amergen tried to show this in its response to AMP-210, but we believe that it underestimated the area considerably. As we discussed, at the ACRS meeting, NRC staff took the position that the total area per bay thinner than 0.736 inches was less than 4 square feet. My questions now are:
i) what is NRC's current assessment of the area in each bay that is thinner than 0.736 inches?
ii) how was that assessment derived and what is the uncertainty in the assessment? and iii) does the NRC accept that the GE modeling cannot be relied upon to establish compliance with the code because it failed to look at sensitivity to the vessel being non-spherical, it could not take account of asymmetric buckling, and it did not model actual situation, which is that multiple areas in each bay of varying shapes are thinner than 0.736 inches?
I look forward to your urgent response. Thank you once again for your thoughtful response to my call.
