50-250 and

-251 Proposed Amendment to Y

0 eratin Licenses DPR-31 and DPR-41 Xn accordance with 10 CFR 50.30, Florida Power 6 Light Com any submits herewith three (3) signed originals and forty (40) copies of a request to amend Appendix A of Facility Operating Licenses DPR-31 and DPR-41.

The proposed changes update Specification 3.7 to be consistent with the "as-built" 125 v DC system as described in FSAR Section 8.2 (Rev.

32 and 33).

The changes are described below and shown on the accompanying Technical Specification pages bearing the date of this letter in the lower right hand corner.

The safety evaluation of this change was submitted as revisions 32 and 33 to the Turkey Point FSAR.

Pa e 3.7-1 Paragraph l.e has been revised to reflect the added batteries and battery chargers.

Pa e 83.7-1 The next to last paragraph has been revised to reflect "as-built" operating conditions.

The proposed amendment 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 it does not involve an unreviewed safety question.

Very truly yours, Robert E. Uhrig Vice President REU/MAS/cpc Attachment cc:
