SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMEMDriENT NO. 52 TO FACILITY ' OPERATING LICENSE NO. DPR-70 AND AMENDMENT NO. 20 TO FACILITY OPERATING LICENSE NO. DPR-75 PUBLIC SERVICE ELECTRIC AND GAS COMPANY, PHILADELPHIA ELECTRIC COMPANY, DELMARVA POWER AND LIGHT COMPANY. AND ATLANTIC CITY ELECTRIC COMPANY SALEM NUCLEAR GENERATING STATION, U!:IT NOS.1 AND 2 00CKET NOS. 50-272 AND 50-311 Introduction
.In a letter dated October 5,1982 Public Service Electric and Gas Company recuested change in. the partial power multiplier (from 0.2 to 0.3) for FI3.- Since tnat time additional infomation was submitted in a letter dated hovember 1E, 19E2.
Disc:ssicn W
Histcrically, increasing the allowable Fu with decreasing cower has been per:-itted by all creviously approved Westinghouse designs.
The increase is peritted by the D!!E crctection setpcints and allows 'or radial pcwer cistribtion changes witn rod insertion to the insertion limit.
The change tc.a larger partial cower multiplier is recuestpd for Salem Units 1 & 2 to allow cptimizatien cf the core loading pattern by minimizing restrictions on F L at low power. This change will also minimize the probability of l.
making rod 'nsertion limit changes to satisfy peaking factor criteria at low power with the control rod banks at the insertion limit.
l As a result of the multiplier change the core limits at 2250 and 2400 psia l
l-are slightly more limiting than previously.
A new set of core limits which 1 -
apply to both ' Salem Units was submitted.
Current reactor core safety limit set-points ' bound core limits' obtained using the increased Ffn at reduced power so no setpoint changes were necessary.
Current f(41) function bounds i
the new axial offset limits; therefore, no changes were required tc the F(6I)
Technical Specification.
Since there were no changes to the overpower and overtempsrature 47 setpoints, no accident reanalysis was required.
i Succary l
We have approved the 0.3 partial power multiplier for WCAP-9500 and other L
plants.
Public Service's request for the Salem Units 1 & 2 changes is similar.
Based on our review we find the. change acceptable.

2-E.~eironmental Consideration We nave determined that the amendments do not authorize a change in effluent types or total amounts nor an increase in power level and will not result in any significant environmental impact. Having made his determination, we have further concluded that the amendments involve an action which is insignificant fran the standpoint of invironnental impact and, pursuant to 10 CFR 51.5(d)(4), that an environnental imoact statement or negative declaration and environ-nental impact aporaisal need nc: be precared in connection with ne issuance of these amendments.
Conclusion We have concluded, based on the considerations discussed above, that:
(1) because the amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated.
does not create the possibility of an accident of a type different from any evaluated 'previously, and does not involve a significant reduction in a margin of safety, the amendment does not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety o'f the public will not be endangered by operation in the prop: sed manner, and (3) such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not ce inimical to the common defense and security or to the health and safety of the public.
