Dear Mr. Anderson:
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION REGARDING SERVICE WATER SYSTEM TECHNICAL SPECIFICATION AMENDMENT REQUEST - BRUNSWICK STEAM ELECTRIC PLANT, UNITS 1 AND 2 (TAC NOS. M85466 AND M85467)
By letter dated December 31, 1992, as supplemented by letter dated July 20, 1993, Carolina Power & Light Company (CP&L or the licensee) requested an amendment to the service water system technical specifications (TS) for the Brunswick Steam Electric Plant, Unit Nos.

Analyses that were developed using a computer model of the BSEP service water system and which were used to support the proposed TS amendment were provided as attachments to the letter dated July 20, 1993. The amendment request proposes:
(1) revision of the number of nuclear service water pumps (NSWPs) required to be operable from two NSWPs per unit to three NSWPs serving the site whenever either unit is in operational condition 1, 2, or 3; (2) revision of the action times associated with certain SWS pump configurations in all operational conditions; i
(3) incorporation of TS surveillance 4.7.1.2.c into proposed action b.4 of TS 3.7.1.2; addition of a quarterly surveillance of the pressure switch logic and valve actuation capability associated with the SWS supply to the emergency diesel generators (EDGs); and (4) complete revision of the bases for TS 3/4.7.1.2.
The staff has completed an initial review of the submittals. We have identified areas where additional information is required to complete our review. Our Request for Additional Information is provided as Enclosure 1.
