8 LORlOA PG'<VER u~ LfGHT QOMPA'lY June 22, 1978 L-78-217 Office of Nuclear Reactor Regulation Attention: Mr. Victor Stello, Jr., Director Division of Operating Reactors U.S. Nuclear Regulatory Commission Washington, D. C. 20555

Dear Mr. Stello:

Re: Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 Thermal and H draul'ic Saf'et L'irni'ts On April 4, 1977, (L-77-106), Florida Power & Light. Company sub-mitted proposed modifications to Technical Specification Figure 2.1-1, Reactor Core Thermal and Hydraulic Safety Limits, Three Loop Operation. The revised figure included the effects of rod bow. This figure has subsequently been revised as a result, of steam generator tube plugging. The attached figures are submitted as an amendment to our April 4, 1977 submittal. Figure 2.1-1 is for operation with < 15 percent steam generator tubes plugged and Figure 2.l-la is for operation with > 15 percent and < 19 percent steam generator tubes plugged. Both figures include a rod bow penalty consistent with our April 4, 1977'ubmittal.

This revision to our proposed amendment to Facility Operating Licenses DPR-31 and DPR-41 has been reviewed by the Turkey Point Plant Nuclear Safety Committee and the Florida Power 6 Light Company Nuclear Review Board. They have concluded that this re-vision does not involve an unreviewed safety question.

Very truly yours,

~ --'/-
