Dear Mr. Denton:

Re: Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-25 I ATWS Im lementation Schedule On August 20, l 985 (L-85-308), FPL notified the NRC that a preliminary schedule had been developed for implementation of the modifications required under IO CFR 50.62 and that based on the schedules it would not be possible to implement the modifications by the Winter of I 986 for Turkey Point Unit 3, nor by the Winter of l987 for Turkey Point 'Unit 4 in accordance with IO CFR 50.62(d) requirements.

~ I FPL is a member of the Westinghouse Owners Group (WOG) and participating in the WOG AMSAC Generic Design Program.

The results of the WOG Program (WCAP-l0858 AMSAC Generic Design Package) were transmitted to the NRC for review and approval on July 25, I 985. WOG has recently indicated to FPL that the NRC Safety Evaluation Report (SER) is not planned to be issued until Mid-November.

FPL needs to evaluate the impact of the SER on each of the designs described in WCAP-l0858 in order to determine which logic is best suited for the Turkey Point Units and when it can be installed.

FPL will provide NRC the Turkey Point schedule to comply with the ATWS rule 90 days after the SER on WCAP-10858 is issued.

Very truly yours, J. W. Williams, Jr.
