Subject:

VIRGIL C. SUMMER NUCLEAR STATION DOCKET NO. 50/395 OPERATING LICENSE t10. NPF-12 TECHNICAL SPECIFICATIONS CHANGE - TSP 910003-1 SNUBBERS (GENERIC LETTER 90-09)

South Carolina Electric & Gas Company (SCE&G) is submittirg a revised amendment request to supplement its submittal of February 4, 1991, which requested a revision to Technical Specification 4.7.7, " Snubbers Surveillance Requirements," in conformance with Generic Letter 90-09.

This revision amends the visual inspection criteria of Surveillance Requirement 4.7.7 to include fasteners for the attachment of snubbers to components and anchorages, makes minor wording changes for clarification, and includes the requirements for the first inspection interval, as discussed with Messers. G. F. Wunder and H. K. Shaw of the NRC on April 16, 1991.

Additionally, Virgil C. Summer Nuclear Station intends to perform a base line inspection during the fall 1991 outage to determine the next visual inspection interval.

This revision to the original submittal of April 16, 1991, does not impact the safety evaluation or the no significant hazards determination.

This proposed technical speciffcation change has been reviewed and approved by the Plant Safety Review Committee and the Nuclear Safety Review Committee.

I declare that the statements and matters set forth nerein are true and correct to the best of my knowledge, information, and belief.

Should you have any questions concerning this issue, please call Mr. Manuel W. Gutierrez, at (803) 345-4392, at your convenience.

Very truly yours, k
