SUBJECT:

EVALUATION OF WCAP-7709L, SUPPLEMENTS 5. 6, AND 7 We have completed our review of Westin use Electric Corporation report

. Supplements 5, 6, and.7 to WCAP-7709L Proprietary) and WCAP-7820 (Non-Proprietary) entitled " Electric Hydrogen Recombiner for PWR Containments".

Our evaluation is enclosed.

As a result of our review, we have concluded, subject to the conditicns in our enclosed evaluation, that the Westinghouse electric hydrogen recombiner is acceptably qualified for the seismic and environmental conditions identified c in Supplements 1 througtr 7 of WCAP-7709L in accordance with the requirements of IEEE 323-1974. Applications using the Westingbouse recombiner must include in their Final Safety Analysis Report infonnation to demonstrate either (1) that accident environmental conditions and plant seismic response spectrum are either within the accepted envelope conditions in WCAP-7709L or (2) that l

. the recombiner is acceptably qualified on some other analytical or experimental basis.-

Accordingly, topical report WCAP-7709L and its Supplements 1 through 7 are acceptable for reference in license applications. Topical report WCAP-7820 and its Supplements 1 through 7 is an acceptable non-proprietary version of WCAP-7709L. When either of these reports is used as a reference, both the

_p;.e3pprietary report and the non-proprietary version mst be referenced.

~

In accordance with established procedures, it is requested that Westinghouse I

g ;; ;3 ssue revised versions of these reports within three. months of receipt of fthis letter to include-this acceptance letter, the enclosed evaluation, and any changes resulting from our. review.
