November 9, 1993 Docket Nos. 50-324 and 50-325 Mr. R. A. Anderson Vice President Brunswick Nuclear Project Carolina Power & Light Company Post Office Box 10429 Southport, North Carolina 28461

SUBJECT:

RESPONSE TO GENERIC LETTER 92-08, "THERMO-LAG 330-1 FIRE BARRIERS,"

BRUNSWICK STEAM ELECTRIC PLANT, UNITS 1 AND 2 (TAC N05. M85526 AND M85527)

By letter dated April 16, 1993, Carolina Power & Light Company (CP&L) provided a response to Generic letter (GL) 92-08 for the Brunswick Steam Electric Plant, Units 1 and 2 (BSEP). The response stated that the qualification of the Thermo-Lag fire barriers installed at BSEP were based on the vendor's testing and installation program.

Although Thermo-Lag barriers were evaluated and may have been considered qualified, the results of recent tests and inspections indicate that further sctions are now Thermo-Lag necessary to address fire endurance and ampacity derating of barriers. The CP&L response stated that appropriate actions to resolve these concerns were being developed through an industry program coordinated by NUMARC, and that CP&L would review the guidance and testing provided through the industry program to determine the appropriate corrective actions required to resolve this issue at BSEP. Compensatory measures _for inoperable barriers are in place and will remain in place until the fire barriers can be declared operable. Although the response to GL 92-08 stated that CP&L would notify the NRC prior to returning these installations to service, be it did not provide a schedule by which the corrective actions would completed.

l In the response to GL 92-08, CP&L indicated that the actions necessary to restore the operability of these barriers would be based on the results of the NUMARC program.

The NRC staff expects that licensees referencing the NUMARC program will review the results and, within 30 days after the completion of the program, inform the NRC of the actions necessary and the schedule for restoring the operability of these fire barriers. In accordance with the reporting requirements of GL 92-08, you are also to confirm in writing, completion of the corrective actions.
