NUCLEAR REGULATORY COMMISSION
%g.....f WASHNGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO.121 TO FACILITY OPERATING LICENSE NO. NPF-12 SOUTH CAROLINA ELECTRIC & GAS COMPANY SOUTH CAROLINA PUBLIC SERVICE AUTHORITY VIRGIL C. SUMMER NUCLEAR STATION. UNIT NO. 1 DOCKET NO. 50-395
1.0 INTRODUCTION
By letten ated July 20, 1994, as supplemented September 20, 1994, South Carolina Electric & Gas Company (the licensee), submitted a request for changes to the Virgil C. Summer Nuclear Station, Unit No. 1 (Summer Station)
Technical Specifications (TS).
The proposed change would modify the TS to allow alternative, equivalent testing of diesel fuel used in the emergency diesel generators (EDG). These alternative methads are necessary due to recent changes in Environmental Protection Agency (EPA) Regulations that are designed to limit the use of high sulfur fuels.
The licensee also proposes to modify the TS by changing the revision level of WCAP-10216-P-A, " Relaxation of Constant Axial Offset Control
- FQ Surveillance Technical Specification," referenced in TS 6.9.1.11.
Titis pertains to the FQ(z) TS (TS 3.2.1 and 3.2.2) and is necessary since Westinghouse revised their methodology in determining FQ(z).
2.0 EVALUATION The Summer Station TS require that diesel fuel oil be sampled in accordance with American Society of Testing and Materials (ASTM) standards D4057, D975-81, D4176-82, 02276-68, and either D1522-79 or D2262-82, at various times during its handling and storage. Alternative tests that accomplish the same goal as these have been developed.
Some of these tests are better and more efficient than the specific tests cited in the TS; therefore, the licensee would like the option of using the alternative tests.
In anticipation of future improvements in testing, the licensee has requested that no specific ASTM standard be cited in the TS; rather, they would like a general statement that "the applicable ASTM standard..." be applied. The Summer Station EDG fuel oil testing program is consistent with the testing program described in Section 5.7.2.17 of the Westinghouse Standard TS. The staff finds this proposed change acceptable.

. The Summer Station TS require that the analytical methods used to determine the core operating limits shall be those previously reviewed and approved by the staff.
In the Summer Station TS this includes WCAP-10216-P-A, " Relaxation of Constant Axial Offset Control - FQ Surveillance Technical Specification."
Westinghouse has since made a revision to this WCAP, and the staff has found this revision acceptable; therefore, the licensee would like to replace the reference to WCAP-10216-P-A with a reference to WCAP-10216-P-A, Rev. lA.
The staff finds this change acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the State of South Carolina official was notified of the proposed issuance of the amendment.
The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
The amendment cnanges a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes the Surveillance Requirements. The NRC staff has determined that the amendment involves 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 amendment involves no significant hazards consideration, and there has been no public comment on such finding (59 FR 51626). Accordingly, the amendment meets 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 amendment.
5.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that:
(1) thera is reasonable assurance t1at the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in complianct with the Commission's regulations, and (3) the issuance of the amendment wili not be inimical to the common defense and security or to the health ano safety of the public.
