By letter dated September 25, 1992, GPU Nuclear Corporation (GPUN) provided a response to NRC Bulletin 92-01, Supplement 1, for Oyster Creek Nuclear Generating Station.
GPUN's response stated that in accordance with the i
requested actions of the bulletin supplement, the hourly fire watch patrols, i
which were already patrolling locations where Thermo-Lag is installed to protect conduit, were expanded to include coverage of drywell penetrations, HVAC duct and the stairway enclosure. The GPUN response also stated that compensating measures for inoperable fire barriers are in place and these l
compensating measures are expected to remain in place until the fire barriers can be declared operable or testing demonstrates successful 1 or 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> barrier performance.
Further you indicated that GPUN will continue to evaluate information regarding the Thermo-Lag 330 fire barrier material as it becomes available. Actions to restore (or confirm) fire barrier operability are being developed through an industry program being coordinated by NUMARC.

GPUN will apply results of the NUMARC program, as appropriate, to the Thermo-Lag fire barriers installed at Oyster Creek.
i The staff has reviewed your response and find it acceptable.
Please inform us when all corrective actions have been completed.
Further NRC review, if any, will be performed by inspection or audit.
