ACRS (14) , a JRBuchanan 1 Gentlemen:-

TBAbernathy On October 2,.1974,:we wrote to'you'concerning' potential discrepancies L

between proposed Technical Specifications' submitted unior 10 CFR 50.46 and those contained in existing Technical ~ Specifications established

~

' for-the purpose of compliance with the Interim Acceptance Criteria (IAC) .

You were asked.to review your ECCS submittals to evaluate any.such dis- .

crepancies and to ' submit the results of. your review. We: have reviewed '

your response dated November 4, 1974. The purpose of.this letter is to ~ . . . , . . .

provide clarifying information regarding the accumulator water level Ed limits that should be being followed at the present time. gq On the basis'of our review, which included a review of the results of e a recent generic Westinghouse IAC study of accumulator water levels, h we have concluded that with the accumulator water levels used-in your '

ECCS submittal dated July 31, 1974, combined'with the limitations set . ,

..forth in your. July 31, 1974 submittal and in Appendix A of the Commission's M

. Order for. Modification to License dated December 27, 1974, the calculated .

Ipeak clad temperature-(and the other criterin for ECCS coolir.g performanco l

set forth in-10 CFR 50.46(b) and-in the 1AC) will be within the criteria of 10 CFR 50.46(b)(1) and of the Interim Acceptanco Criterin.

Accordingly, operation with accumulator water Icyci at 700 ft3 minitram, which wo understand is the present invol, properly conforms to the requirc-cents of the Co.: mission's IAC, as well as the criteria of 10 CFR 50.46. As n an administrative followup to this letter of clarification, you are requested ,

to submit an application for an amendment to your licenso to reflect this .

water level limit in your existing Technical Specifications. [
