Analyses" i This letter supplements the Reference A and Reference B submittats with an oath or affirmation statement in accordance with 10 CFR 50.30(b). It also clarifies the requested NRC action. ,

in Reference A, Boston Edison Company (BECo) requesteu NRC review and approval of the BECo net positive suction head (NPSH) analysis that included credit for post-accident containment pressure.

The clarification involves the BECo request for NRC review and approval of a license amendment / g i under 50.90 to credit containment pressure in post-accident NPSH analyses. As part of that request, we recognize the _NRC will also need to review and approve the evaluation submitted in[r/u /

Reference A that raised the design seawater temperature from 65F to 75F resulting in a reused containment heat removal analysis. .This scope does not impact the conclusion of the cigniscant hazards determination.
