Daniel R. Muller In response to your April 10 note on GESSAR II, I suggest you consider the following:

1.

AEB GESSAR Review Concerns Problems Proposed Solutions o Selecting Source Terms for Staff a Use judgment and available ASTP0 Design Review contractor calculations w/RES &

BHL o Selecting Source Terms for Potential o Obtain agreement areng BNL, RSB, Design Improvements and AEB, for assessing aerosol behavior in suppression pool, piping, leak plugging using judgment where ASTPD methods unavailable or unbelievable..

Plug GE into position, if possible, and review their resubmittal (due 4/30). AEB proposes to stop debate over suppression pool DF hy taking a position, and concentrating on more risk dominant by-pass sequences.

If later EPRI tests and GE/Ptil code coc'parisons show staff position not adequate, staf f will reconsider.

O Sites Used by Staf f for Assessing o Use o.ippingport-Waterford-Holf Value-Impacts Cr.ek as suite of three to enconpass site variations.

With regard to ACRS Subcomittee neetings, it would apppear affvantageous to have a series of such reetings on a nunber of technical subjects.

'A Roger J. tiattson their contractors will likely be involvec in discussions of new source terms before APS finishes their ASToo review. The level of such RES involvenent should should be riiscussed with Pernero.
