Mr. Gerald B~ Slade Plant General Manager Palisades Plant Consumers Power Company 27780 Blue Star Memorial Highway Covert, Michigan 49043
Dear Mr. Slade:
December 10, 19_93-
SUBJECT:
PALISADES PLANT - RESPONSE TO GENERIC LETTER 92-08, "THERMO-LAG 330-1 FIR[ BARRIERS"
{TAC NO. M85582)
By letter dated April 14, 1993, you provided a response to Generic Letter_
{GL) 92-08 for Palisades.
Your response states that the Thermo-Lag fire barriers installed at Palisades were supplied by the vendor with the associated fire endurance tests which were representative of the configurations us~d in the plant_and that the fire barrier.configurations installed at the plant are consistent-with the qualification test assembly configurations supplied by the vendor at the time of_ installation.
Your response states that altho~gh you have not performed specific evaluations of the possible deviations from the tested configuration, the fire barrier installations were deemed acceptable by vendor inspectors or by vendor-trained qua 1 i ty inspectors.
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 ampacityderating 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-f installations at Palisades. 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 actions would be completed.
In your response to GL 92-08 you indicated that the actions necessary to restore 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 NUMARC program and any potential barrier upgrades resulting from this testing.
In accorda]e with the reporting requirements of GL 92-08, you are also to confirm in
\\
writing, completion of the corrective actions.
