Dear Mr. Hunger:
SUBJECT:
PEACH BOTTOM ATOMIC POWER STATION, UNITS 2 AND 3, AND LIMERICK i
GENERATING STATION, UNITS 1 AND 2, RESPONSE TO GENERIC LETTER'92-08,.
j
" THERM 0-LAG 330-1 FIRE BARRIERS" (TAC NOS. M85585, M85586, M85565 i
AND M85566)
By letter dated April 16, 1993, you provided a response to Generic Letter (GL) 92-08 for Peach Bottom Atomic Power Station (PBAPS), Units 2 and 3 and Limerick Generating Station (LGS), Units 1 and 2.
Your response states that the Thermo-Lag fire barriers installed at PBAPS and LGS were qualified by the vendor (or Architect Engineer) based on the vendor's (or Architect Engineer'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 confinurations. Your response also states that deviations from the tested configuration have been evaluated.
j 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 NUMARC and you would apply the results of the industry program, when completed, to the Thermo-Lag 330-1 installations at PBAPS and LGS.
- Compensatory measures for inoperable barriers.are in place and will remain in place _until the fire barriers can be declared. operable. However, because you had not determined specific corrective actions, your response to GL 92-08 did not provide a schedule by which corrective actions would be-completed.
In your response to GL 92-08, you indicated that the actions necessary to 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.
In accordance with the reporting requirements of GL 92-08, you are also to confirm in writing, completion of the corrective actions.
