Re: Pilgrim Nuclear Power Station By letter dated August 8,1979, Boston Edison. Company (BEco) was requieted to provide certain analyses and test results concerning the adequacy of station electric distributions system (SEDS) voltage at the Pilgrim Nuclear Power Station.

Our contractor, Lawrence Livermore Laboratory (LLL) has reviewed your submittals on this subject and concluded that the SEDS at Pilgrim is adequate to supply acceptable voltage to the class 1E equipment under worst case donditions.

We have reviewed the LLL Technical Evaluation Report and agree with its conclusions. The enclosed Safety Evaluation Report documents our findings.
