Requested Completion Date:
ASAP Review Status:
Complete In our memorandum of January 17, 1984, we provided our input for Supplement No. 5 to the SER and indicated that our review of the WNP-2 fire protection program was complete.
By letter dated July 17, 1984, the licensee requested approval for the installation of carpeting in the control room.
Attached is our evaluation.
We conclude that the proposed installation of carpeting in the control room is an acceptable deviation from Section C.7.b. of BTP CMEB 9.5-1.

s Chemical Engineering Branch / Fire Protection Section Supplemental Safety Evaluction Report WPPSS Nuclear Project No. 2 Docket No. 50-397 9.5.1 Fire Protection Program In our SER and in Supplement No. 5 to the SER, we evaluated fire protection in the Control Room Complex.
By letter dated July 17, 1984, the licensee requested approval for the installation of carpeting in the control room so as to: (1) reduce background noise; (2) enhance ambience and comfort, (3) minimize fatigue of personnel; and (4) improve overall control room appearance.
We were concerned that the carpet might represent a significant fire hazard from the standpoint of overall flammability and the potential for smoke production, if ignited.
In the July 17, 1984 letter, the licensee provided the results of fire tests on the proposed carpet which demonstrated that it represents no greater fire hazard than the previously approved vinyl asbestos tile that it will replace.
Specifically, the Critical Radiant Flux was determined to be 1.01 watts per square centimeter as determined by the test method in ASTM E-648, which enables the carpet to be considered as a Class I interior finish.
The smoke development rating of the carpet was determined to be less than 250, as determined by the test method in ASTM E-662.
This compares to a flaming smoke development of 325 for vinyl asbestos tile. We conclude that the installation of the carpet will not significantly decrease the level of j
fire safety in the control room and, therefore, represents an acceptable l
deviation from Section G.7.b of BTP CMEB 9.5-1.
