UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 August 9, 1995 Mr. B. Ralph Sylvia Executive Vice President, Nuclear Niagara Hohawk Power Corporation Nine Mile Point Nuclear Station P.O.

SUBJECT:
RESPONSE
TO REQUEST FOR ADDITIONAL INFORMATION REGARDING USE OF THERMO-LAG 330-1 AT NINE MILE POINT NUCLEAR STATION, UNIT 2 (NMP-2)
(TAC NO. H85575)
Dear Mr. Sylvia:
By letter dated December 14, 1994, Niagara Hohawk Power Corporation (NMPC) responded to our September 15, 1994, request for additional information regarding use of Thermo-Lag 330-1 at NMP-2.
NHPC's response stated that NHPC has decided to replace all existing Thermo-Lag 330-1 fire barriers at NMP-2 with an acceptable fire barrier material except for the heating, ventilation, and air conditioning (HVAC) ducts in each emergency diesel generator (EDG) day tank room and that this modification is scheduled for field completion by December 31, 1995.
NMPC stated that the fire barriers for HVAC ducts in each EDG day tank room have been derated without reducing the effectiveness of the fire protection program based on provisions in Branch Technical Position CMEB 9.5-1, Revision 2, Position C.7.i(2).
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 iq Generic Letter 92-08, "Thermo-Lag 330-1 Fire Barriers,"
has been provided and our actions tracked by TAC No. M85575 are complete.
Please advise us in writing when the modification described in NMPC'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.
