Dear Mr'. Case:

Re: Turkey Point Units 3 & 4 Docket Nos. 50-250 and 50-251 Reactor Vessel Surveillance Ca Power G Light Company hereby submits fifteen (15) copies sules'lorida of a summary technical report on the results of Turkey Point reactor vessel integrity analyses. The analyses were performed in accordance with 10 CFR 50, Appendix G, Section V.B.

The present report series updates previously submitted analyses for Turkey Point Units 3 and 4. The series includes an ASME III Appendix G Analysis, a fatigue crack growth evaluation, and a fracture mechanics evaluation of the pressure vessel subjected to postulated accident conditions.

April 7, 1977, a meeting was held with staff members from On Operating Reactors Branch-g3. At that meeting the weld metal surveillance data for the Turkey Point Unit 3 it was shown that reactor vessel represents not only the core midplane circumferential welds in Unit 3, but in Unit, 4 as well. Data supporting this con-clusion has been submitted to the Division of Operating Reactors.

Based on the results of the April 7 meeting and the results of the present report series, the Turkey Point Units 3 and 4 reactor vessels are in full compliance with 10 CFR 50, Appendix G.

Very truly yours, Robert E. Uhrig Vice President REU/MAS/cpc Attachments cc: Mr. James P. O'Reilly, Region II Robert Lowenstein, Esquire 772S70305 PFOPLE SERVING PcQPLE
