Dear Hr. Sylvia:
By letter dated December 14,
- 1994, Niagara Mohawk Power Corporation (NHPC) responded to "our September 15, 1994, request for additional information regarding use of Thermo-Lag 330-1 at NHP-1.
NMPC's response stated that NHPC has decided to replace all existing Thermo-Lag 330-l,fire barriers at NHP-1 with an acceptable fire barrier material and that this modification is scheduled for field completion by December 31, -1995.
The NRC staff has reviewed NHPC's December 14,
- 1994, response.
Based on our
- review, we have determined that except for an assessment of the ampacity impact of the Thermo-Lag material on cable life for previous operation of safety-related circuits, the information requested in Generic Letter 92-08, nThermo-Lag 330-1 Fire Barriers,"
has been provided and our 'actions tracked by TAC No. M85574 are complete.
Please advise us, in writing, when the modification described in NHPC's December 14, 1994, letter has been implemented.
NHPC should retain all documentation related to the resolution of the concerns with Thermo-Lag fire barrier systems for future NRC audits or inspections.
This documentation should include an evaluation of the ampacity impact of Thermo-Lag material on cable life for previous operation of safety-related circuits.
If you have any questions regarding this matter, please contact me at 301-415-1409.
