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 Evaluation is enclosed.
In view of the foregoing, the Technical Specifications of License No. DPhil i
