SUBJECT:

James A. FitzPatrick Nuclear Power Plant Docket No 50-333 Additional Information and Errata Regarding Two Appendix R to 10 CFR 50 Exemption Requests

REFERENCES:

1. NYPA letter, R. J. Converse to NRC dated July 31,1991 (JAFP-91-0454). Exemption request for area wide suppression in the battery room corridor.

2. NYPA lettei, R. J, Converse to NRC dated July 31,1991 (JAFP-91 0455). Exemption request for fire detection in the turbine building,

Dear Sir:

. This letter details the specla! circumstances associated with two exemption requests filed by the Authority in References 1 and 2. Section 50.12(a)(2) of Title 10 states that the Commission will not consider gianting an exemption roquest unless special circumstances are present.

This letter also corrects an error in the engineering assessment included as an attachment to Reference 2.

Special Circumstances Associated with Area Wide Suppression in the Battery Room Corridor Exemption Request (Reference 1)

Application of the regulation (Section Ill.G.3 of Appendix R to 10 CFR 50) is not necessary to achieve the underlying purpose of the rule. As detailed in the attachment to the Authority's exemption request (Reference 1), the addition of a fixed suppression system in the FitzPatrick battery room corridor would not significantly improve the level of fire protection, Existing fire protection systems, features and personnel adequately.

ensure that FitzPatrick's safe shutdown capability is protected from the effects of fire and that the plant could be safely shutdown in the event of a fire.

tio

Specifically, alternate shutdown capability outsido of the area, and automatic detection for the hazards present have boon provided. ciros would be detected at the incipient stage, am) the fire brigado dispatched. Extinguishers and hose stations are installed in the area of the battery room cotridor for use by the firo brigade.

Special Circumstan.:es Associated with Area Wido Detection in the Turbine Building Exemption Roquest (Roference 2)

Application of the regulation (Section Ill.G.3 of Appendix R to 10 CFR S0) is not necessary to achlove the underlying purpose of the rule. As detailed in tho attachmont to the Authority's exemption request (Reference 2), the addit}on of a dotection sysictn in the FitzPatrick Turbine Building would not significantly improve the lovel of firo protection.

Existing fire protection systems, features and personnel adequatoly ensure that FitzPatric!fs safe shutdown capability is protected from the effects of fire and ti at the plant could be safely shutdown in the ovent of a fire.

Specifically, there are mlnlmal exposed combusUblo matarats in the lismediato vicinity and adjacent locations with significant exposure fire hazards are protected by automatic wet pipe sprinkler systems. The actuation of thoso adjacent supprossion systoms would control or extinguish postulated firos. Safo shutdown capability would not be affected because West Electric Bay ventilation is unaffected by a firo in the area.

Error in Engineering Assessment included with Reference 2 in Section 5.0 (page 5) of the engincoring assessment included with Reference 2, tho Authority incorrectly stated that, "...thore will be no impact on safe shutdown capability since the availability of ventilation to the East Electric Bay...' This last portion of this sentence should road "to the Wett Electric Bay."

If you have any questions regarding olther of these exemption requests, please contact Mr. J. A. Gray, Jr.
