Mr. Robert Bernero, Director Division of BWR Licensing Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Bernero:

Re: Amendment 27 to Application to Operating License Nine Mile Point Unit 2 Docket No. 50-410 In accordance with 10 CFR 50.30(c)(l) and your March 29, 1983 letter, enclosed are three originals and 60 copies of Amendment 27 to the Final Safety Analysis Report. These changes incorporate certain responses into the text of the Final Safety Analysis Report. Also included are changes that have resulted from our continuing review of these documents.

In the original submittal of the Final Safety Analysis Report on January 25, 1983, we requested proprietary status for certain figures in Section 6A in accordance with 10CFR2.790. The September 21, 1983 letter from A. Schwencer to G. K. Rhode approved this proprietary status. Amendment 27 contains updates to a figure in Section 6A.

Also enclosed is the Summary of Incorporated Changes. This list is to assist the Nuclear Regulatory Commission in reviewing Amendment 27.

Very truly yours, C. V. Mangan ) $0 .II/

Mr. Robert Bernero, Director Division of BWR Licensing Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Bernero:

Re: Amendment 27 to Application to Operating License Nine Mile Point Unit 2 Docket No. 50-410 In accordance with 10 CFR 50.30(c)(l) and your March 29, 1983 letter, enclosed are three originals and 60 copies of Amendment 27 to the Final Safety Analysis Report. These changes incorporate certain responses into the text of the Final Safety Analysis Report. Also included are changes that have resulted from our continuing review of these documents.

In the original submittal of the Final Safety Analysis Report on January 25, 1983, we requested proprietary status for certain figures in Section 6A in accordance with 10CFR2.790. The September 21, 1983 letter from A. Schwencer to G. K. Rhode approved this proprietary status. Amendment 27 contains updates to a figure in Section 6A.

Also enclosed is the Summary of Incorporated Changes. This list is to assist the Nuclear Regulatory Commission in reviewing Amendment 27.

Very truly yours, PERIL C. V. Mangan Senior Vice President JM:ja 1853G Enclosures Resident Inspector D~S xc: W. A. Cook, NRC a)S>~
