SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULAJ13 RELATED TO AMENDMENT NOS.182 AND 163 TO FACILITY OPERATING LICENSE NOS. DPR-70 AND DPR-75 PU8LIC SERVICE ELECTRIC & GAS COMPANY PHILADELPHIA ELECTRIC COMPANY DELMARVA POWER AND LIGHT COMPANY ATLANTIC CITY ELECTRIC COMPANY SALEM NUCLEAR GENERATING STATION. UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 AND 50-311
1.0 INTRODUCTION
By letter dated January 4, 1996, the Public Service Electric & Gas Company (the licensee) submitted a request for changes to the Salem Nuclear Generating Station, Unit Nos. I and 2, Technical Specifications (TS).
The reque;sted changes would change TS 3/4.8.2.5, "28-Volt D.C. Distribution - Operating."
The amendment for Unit I would make Unit I requirements similar to Unit 2 by defining the specific battery chargers that are required for each train and by restricting the use of the backup battery charger to 7 days. The amendments would for both units also require that the 28-Volt DC bus be energized for that bus to be OPERABLE.
2.0 EVALUATION The 28-Volt DC power distribution system consists of two 28-Volt batteries and four battery chargers.
Each battery has a primary charg:r powered from a different Vital AC bus (A or B), and a backup charger. The backup charger for both batteries is powered from the same Vital AC bus, the C bus.
TS 3/4.8.2.5 for Unit 2 specifies the primary battery charger for each battery and limits the period of time that one battery can be connected to the backup charger to 7 days. These provisions preclude the possibility of both i
batteries being supplied from the same bus, the C bus. The proposed amendment incorporates these provisions into the TS 3/4.8.2.5 for Unit 1.
Since these provisions preclude the possibility of both batteries being supplied from the same bus, are more conservative than the existing TSs, and are consistent with Unit 2 TSs, the staff finds them acceptable.
The proposed changes also require that the buses be energized in ACTION statement 3.8.2.5.a. for both ~ units.
This is consistent with the Limiting Condition for Operation 3.8.2.5 which requires that both 28-Volt DC trains be OPERABLE and energized. Therefore, the staff finds it acceptable.

3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the New Jersey State official was notified of the proposed issuance of the amendments.
By letter dated February 15, 1996, the State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
1 The amendments change a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
The NRC staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no
=
public comment on such finding (61 FR 5818). Accordingly, the amendments meet l-the eligibility criteria for categorical exclusion set forth in 10 CFR 1
51.22(c)(9).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.
5.0 CONCLUSION
l j
The Commission has concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such
-activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
