}AFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NOS.138 AND 116 TO FACillTY OPERATING LICENSE NOS. DPR-70 AND DPR-75 EVBLIC SERVICE ELECTRIC & GAS COMPANY PHILADELPHIA ELECTRIC CDMPANY DELMARVA POWER AND LIGHT COMPANY ATLANTIC CITY ELECTRIC COMPANY SALEM NUCLEAR GENERATING STATION. UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 ANDJD-311 1.0 INTRODUCTI.@
By letter dated August 14, 1992, the Public Service Electric & Gas Company, Philadelphia Electric Company, Delmarva Power and Light Company and Atlantic City Electric Company (the licensees) submitted a request for changes to the Salem Nuclear Generating Station, Units 1 and 2, Technical Specifications (TS). The requested changes would modify Technical Specification 3/4.3.2,
" Engineered Safety Features Actuation System Instrumentation," Limiting Conditions for Operation, Action Requirements, and Surveillance Requirements, iacluding associated tables.
These changes provide consistency between the units, address various administrative discrepancies, and ensure technical accuracy. The requested changes would also allow entry into Mode 1 with one Main Feedwater pump out-of-service, allow the ACTION statement in Functional Units 4.a. and 4.b. to require taking the Unit to one mode below the Mode of Applicability instead of two, and delete all references to three and four loop operation.
2.0 EVALVATION A.
Renumberina of Line items Renumbering Limiting Condition for Operation 3.3.2 and Surveillance Requirements 4.3.2.1, 4.3.2.2, and 4.3.2.3 as 3.3.2.1, 4.3.2.1.1, 4.3.2.1.2, and 4.3.2.1.3 respectively, for Unit 2 only, is to be consistent with Salem Unit I and to be more consistent with other specifications in the Salem Unit 2 Instrumentation Chapter.
Renumbering of line items within a specification is an administrative change, the staff = concludes the proposed Technical Specification changes are acceptable.

The present Action requires Unit I to be taken two modes below the mode of
l l
. applicability.
Changing to the new Action 23 would take the Unit to one mode below the mode of applicability, which is consistent with the Westinghouse Standard Technical Specifications.
This also makes the Unit I technical specification consistent with Unit 2.
Changing the referenced Action for Unit 2 is editorial due to the renumbering of the Actions.
The required Action remains the same. The staff finds these changes acceptable.

3.0 STATE CONSULTATION
in accordance with the Commission's regulations, the New Jersey State official was notified of the )roposed issuance of the amendments. The State official had no comments on t1e proposed no significant hazards determination.
The State official had one editorial comment that has been addressed by the staff (see paragraph B.1 of this safety evaluation).
4.0 ENVIRONMENTAL CONSIDERATION
The amendments change t. 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 (57 FR 45087). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 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
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.
