Vassallo, Chief Operating Reactors Branch No. 2 Division of Licensing United States Nuclear Regulatory Commission Washington, DC 20555 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NOS.1 AND 2 DOCKET NOS. 50-325 & 50-324/ LICENSE NOS. DPR-71 & DPR-62 IN-SERVICE INSPECTION - ASME CODE RELIEF REQUEST

Dear Mr. Vassallo:

Carolina Power & Light Company submitted an ASME code relief request concerning the reactor instrumentation penetration excess flow check valves on May 2,1985. On June 4,1985 a conference call was held with members of your staff concerning this submittal. As a result of that conference call, the Company committed to provide ~

additional information to facilitate the review of our requcst.

The valves associated with this exemption request are located on water filled instrumentation lines. As indicated in our May 2 submittal these valves will be cycled ever 18 months in accordance with Technical Specification 4.6.3.4. In addition, every 18 months the valves will be tested by a vacuum procedure to verify operability. The acceptance criteria of this test is to be a rapid decrease in the initial flow after valve closure. This flow decrease will verify proper valve functioning and confirm proper reactor trip gauge board light indication.

The attachment to this letter lists the valves associated with this request.

Should you have any questions concerning this request, please contact Mr. R. J. Fasnacht at (919) 836-7318.

Yours very truly,
