March 17,- 1980 File: -NG-3514(B) SERIAL NO: NO-80-422 Office'of Nuclear Reactor Regulation Attention: Mr. D. G. Eisenhut, Acting Director Division of Operating Reactors United States Nuclear Regulatory Commission

-Washington, D. C. 20555 Brunswick Steam Electric Plant, Unit Nos. 1 and 2 Docket Nos. 50-325 and 50-324 License Nos. DPR-71 and DPR-62 LWR Primary Coolant System Pressure Isolation Valves

Dear Mr. Eisenhut:

This letter is in response to your February 23, 1980 letter which requested information to describe isolation valve configuration and to indicate if an Event V isolation valve configuration exists within the Class I boundary of the high pressure piping connecting Primary Coolant System (PCS) piping to low pressure system piping.

Carolina Power & Light Company (CP&L) submits the following information for the Brunswick Steam Electric Plant (BSEP) Unit Nos. 1 and 2.

.Only two systems at BSEP, Residual Heat Removal (RHR) and Core Spray

'(CS), meet the criteria of a system where PCS piping and low pressure piping both exist on the same system. .The valve configuration on both of these systems at BSEP~ consists of.a. check valve with two motor-operated valves in series. This is not one of the valve configurations of concern addressed in your letter. These motor-operated valves are Type "C hak rate tested at each refueling outage per 10CFR50, Appendix J.

We cr*- . that this information satisfies your request for Event V isolation v ..s information.
