'FLORIDA POWER 8( LIGHT COMPANY April 15, 1982 L-82-149 Office of Nuclear Reactor Regulation Attention: Mr. Darrell G. Eisenhut, Director Nuclear Reactor Regulation United States Nuclear Regulatory Commission RBQP]pp~ 9 Washington, D.C. 20555

Dear Mr. Ei senhut:

4 igfQ gg ~ 1Q noc Re: Turkey Point Units 3 8 4 Docket Nos. 50-250 and 50-251 '4 Proposed Licensed Amendments 5$ Steam Generator Tube Plugging ECCS Analysis In accordance. with 10 CFR 50.30 Florida Power 8 Light Company submits herewith three signed originals and forty copies of a request to amend Appendix A of Facility Operating Licenses DPR-31 and DPR-41.

Our NSSS vendor (Westinghouse Electric Corporation) has completed a 10 CFR 50.46 ECCS reanalysis for Turkey Point Units 3 and 4 with the replaced model 44F steam generator for large br eak LOCA (Cn = 0.4 and CD = 0.6) using 1981 version of the Westinghouse EPICS Evaluation Model. This the'ecember analysis incorporates the most recent standards and ECCS model improvements and is attached in support of this request.

The peak clad temperature computed for the FPL limiting break (0.4 DECLG) is 2195'F at an Fq of 2.30 for 5$ steam generator tube plugging.

To allow usage of the same specification for both units, the proposed amendment will have two values where necessary. One will be for < 5$ tube plugging and the other will be for tube plugging of ) 5$ and < 287,. We anticipate that Unit 4 will be able to use the 5g, value following steam generator repairs.

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

Page 3.2-3a The steam generator tube plugging limit in Specification 3.2.6a is shown for up to 5$ and for from 5$ up to 28%%d and for F~ values of 2'.30 and 2.125, respectively.

Re: Turkey Point Units 3 8 4 Docket Nos. 50-250 and 50-251 Pro osed Licensed Amendments Figure 3.2-3a A new K(Z) curve has 'been added to reflect the new steam:generator tube plugging limit and new F~.

The proposed amendment has been approved by the Turkey Point Plant Nuclear Safety Committee and the Florida Power 5 Light Company Nuclear Review Board.

We have determined .that since this request involves a single safety issue and a duplicate amendment, the request should be classified as a class I and III amendment pursuant to 10 CFR 170. Accordingly, a check for $ 4,400 i s enclosed.

Very truly yours, Robert E. Uhrig Vice President Advanced Systems 8 Technology REU/PLP/mbd Attachments cc: Mr. James P. O'Reilly, Region II Harold F. Rei s, Esquire
