Dear Mr. O'Reilly:
Re: St. Lucie Unit No. 2 Docket No. 50-389,50.55(e),82-014 Valves Will Not Respond to Command Signals On June 30, 1982, Florida Power & Light Company'(FPL) notified Region II Office of Inspection and Enforcement, in accordance with the requirements of 10 CFR 50.55(e) of a potential deficiency regarding the failure of reactor shutdown cooling bypass valves to respond to command signals.
FPL is drafting the final report at this time and will submit it by February 25, 1983.
Very truly yours,
