Dear Hr. Parrish:
SUBJECT:
CLOSEOUT OF NRCB 92-01, SUPPLEMENT 1, "FAILURE OF THERMO-LAG 330 FIRE BARRIER SYSTEM" (TAC NO. H83950)
By letter dated September 28,
- 1992, you provided 'a response to NRC Bulletin 92-01 for WNP-2.
Your response stated that you had identified all areas with 1-or 3-hour Thermo-Lag 330 fire barrier material, and that these ar'eas had been placed on a one-hour fire watch tour.
After extensive discussion with the NRC staff, your letter dated April 13, 1993, provided in response to Generic Letter (GL) 92-08, identified the Thermo-Lag 330 fire barriers as inoperable.
In addition, you described your long-term corrective action program to ensure or restore operability.
This long-term corrective action involves your participation in the NUMARC Thermo-Lag Test Program.
This additional information satisfactorily completes your response to NRCB 92-01, and TAC M83950 is considered closed.
All further review of the Thermo-Lag issue, including implementation of corrective actions, will be conducted under our evaluation of your response to GL 92-08 (TAC H85624).
This review will consider the additional information provided in your June 23, 1993 letter that revised your original response to GL 92-08, including an assessment of the acceptability of the scope and schedule of your proposal for identification of additional Thermo-Lag installations at WNP-2.
