Dear Mr. Utley:

SUBJECT:

CHANGE TO BASES OF BRUNSWICK TECHNICAL SPECIFICATION 3/4.5.3.1, " CORE SPRAY SYSTEM (CSS)"

Re: Brunswick Steam Electric Plant, Units 1 and 2

\

By letter dated December 3, 1985, the Carolina Power & Light Company (CP&L) submitted proposed changes to the Bases to the Technical Specifications appended to Facility Operating License Nos. DPR-71 and DPR-62 for the Brunswick Steam Electric Plant (BSEP), Units 1 and 2. The proposed changes would modify the Bases for Technical Specification Section 3/4.5.3.1 related to the operability of the core spray system. The proposed change would clarify the Bases to indicate that 50,000 gallons of water is the minimum required in the condensate storage tank to assure operability of the core spray system during operational conditions 4 or 5.

We have reviewed your request and agree that the minimum volume of water required for core spray system operability in operational condition 4 or 5 is 50,000 gallons. This volume corresponds to a condensate storage tank (CST) level of 150,000 gallons where the lower 100,000 gallons is dedicated, by way of stand pipes, for use by the high pressure coolant injection system and reactor core isolation cooling system. We concur that the proposed change to the Bases is appropriate to clarify that it is not 150,000 gallons that is l required for core spray system operability, but that the water in the CST must be at the 150,000 gallon level. A copy of our evaluation is enclosed.

Because the proposed change is to the Bases and not to the Technical Specifications, en amendment to the license is not required and is not being issued. We have, however, revised page B 3/4 5-2 for Brunswick Unit 1 and page B 3/4 5-2 for Unit 2. A copy of these revised pages is enclosed.

Sincerely, Original signed by/

Daniel R. Muller, Director BWR Project Directorate #2 l
