l Carolina Power & Light Company JUL 29 1982 Office of Nuclear Reactor Regulation ATTN:
Mr. D. B. Vassal'lo, Chief Operating Reactors Branch No. 2 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 TECHNICAL SPECIFICATION REVISION REQUEST DEGRADED VOLTAGE RELAYS
Dear Mr. Vassallo:
SUMMARY
In accordance with the Code of Federal Regulations, Title 10, Parts 50.90 and 2.101, Carolina Power & Light Company (CP&L) hereby requests revisions to the Technical Specifications (TS) for the Brunswick Steam Electric Plant (BSEP) Unit Nos. I and 2.
The revisions reflect a change in emergency core cooling system (ECCS) actuation instrumentation setpoints and concomitant surveillance requirements.
DISCUSSION Following investigation of a June 28, 1982 reactor scram on BSEP Unit No. 1, CP&L determined Degraded Voltage Surveillance Tests on Unit I were not being performed. The NRC was promptly notified of this discovery.
Continuing investigation of the above included a thorough examination of the NRC Safety Evaluation and Staff Position Relative to Emergency Power Systems (EPS) for Operating Reactors (dated June 3, 1977), the installed plant modification ard proposed TS (filed March 6, 1979), and NRC approval of the TS changes (dated June 11, 1980). Results of the investigation determined incorrect relays were referenced in the plant modification and therefore, the incorrect setpoint values were incorporated in TS.
Again, the NRC was promptly notified regarding the investigation results.
Research indicates TS Table 3.3.3-2, Item 5.a. describes Balance-of-Plant (B0P) busses IC, 1D, 2C, and 2D for Device 27.
The correct relay should have been Emergency Busses E-1, E-2, E-3, and E-4, Device 27/59E. The enclosed TS pages correct the aforementioned discrepancies.
