This a fers to your m quest dated Manh 17, 1967, for authorisation of

- changes in the Technical Specifications of Prwisional Operuting License i l No. EPhil pursuant to the prwielens of Section 50.59 of the Ma=%'s '

l l

l mgulations. The p m posed changes would atthorise deletion of the sepa mte

aquimeents on maxima boiler power fmetion and minimum maimulation ,

flow for a given total mactor power, and would incorporate a mquirement  ;

for a miniana =11amh1= bumout mtio. 1hese changes are necessary to -

enable ruanter operation at full power. We have designated this mgasst l l

as Pmposed Change No.13. ,

We have concluded that Paposed Q1mnes No. 33 does not prueent significant

- hasards considerutions not described or implicit in the Final Hasards .

Smenary Report, and that there is zwasonable assumnoe that the health and safety of the public will not be endangerud. A copy of our m lated Safety ,
