SUBJECT:

James A. FitzPatrick Nuclear Power Plant Docket No. 50-333 Withdrawal of Exemption Request Regarding Appendix R to 10 CFR 50 Use of Core Sorav to Achieve Safe Shutdown

REFERENCES:

See below. l

Dear Sir:

As the result of recent developments, and discussions with indus+ry representatives and the members of the NRC staff, the Authority is withdrawing its recent exemption request (Reference 1). .This exemption dealt with the use of core spray for reactor coolant makeup I to achieve safe shutdown in one fire area at the Auti:crity's James A. FitzPatrick Nuclear 6 Power Plant.

The BWR Owners' Group, in cooperation with General Electric and the Authority, has developed a position paper that addresses the use of safety relief valves (SRVs) and low-pressure systems (including core spray) as redundant safe shutdown paths on a generic basis. The paper, which was recently submitted to the NRC (Reference 3), examines the acceptability of using low-pressure systems from regulatory, safety and risk significance perspectives. The paper concludes that the use of SRVs and low-pressure systems is an acceptable methodology for achieving safe shutdown in accordance with the requirements of Section Ill.G.1 and 2 of Appendix R to 10 CFR 50.

The Authority will continue to work with the BWROG to resolve the NRC's concerns regarding this issue. However, the Authority may re-submit this exemption request if the generic resolution of this issue is not consistent with the current FitzPatrick licensing basis.

<4 ,a j The withdrawal of this exemption does not alter the Authority's previously stated position (Reference 2) regarding the ability of low-pressure systems (including core spray) to achieve safe shutdown at FitzPatrick and FitzPatrick's compliance with the requirements of Appendix R to 10 CFR 50.

There are no new commitments made by the Authority in this letter. If you have any questions, please contact Ms. C. D. Faison.
