Dear Mr. McNeekin:
SUBJECT:
MCGUIRE NUCLEAR STATION, UNITS 1 AND 2 - RESPONSE TO GENERIC LETTER 92-08, " THERM 0-LAG 330-1 FIRE BARRIERS" (TAC N0s. M85568 and M85569)
By letter dated April 16, 1993, you provided a response to Generic Letter (GL) 92-08 for McGuire Nuclear Station, Units 1 and 2.
Your response states that the Thermo-Lag fire barriers installed at McGuire Nuclear Station, Units 1 and 2, were qualified by the vendor based on the vendor's understanding of the NRC guidance, in existence at the time of installation, and that the fire barrier configurations installed at the plant are consistent with the qualification test assembly configurations.
Your response also states that deviations from the tested configurations have been evaluated.
Although Thermo-Lag barriers were evaluated and may have been considered qualified, the results of recent tests and inspections indicate that further actions are now necessary to address fire endurance.and ampacity derating of Thermo-Lag barriers.
Your response states that appropriate actions to resolve these concerns are being developed through an industry program coordinated by l
NUMARC and you would apply the results of the industry program, when completed, to the Thermo-Lag 330-1 installations at McGuire Nuclear Station, Units 1 and 2.
Compensatory measures for inoperable barriers are in place and will remain in place until the fire barriers can be declared operable.
Your response to GL 92-08, however, did not provide a schedule by which corrective l
actions would be completed.
l l
In your response to GL 92-08, you indicated that the actions necessary to j
restore (or confirm) the operability of these barriers will be based on the results of the NUMARC program. The 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 including plant specific or unique fire barrier configurations that are not bound by the NUCMAC Program.
In accordance with the reporting requirements of GL 92-08, you are also to confirm in writing, completion of the corrective actions.
