Dear Mr. Eisenhut:
Re:
Turkey Point Units 3 and 4
Docket Nos. 50-250 and 50-251 Pressure Vessel Materi al Fracture Tou hness NUREG-0744 Rev.
1 NUREG-0744, Rev.
1 outlines an acceptble method of fracture mechanics analysis to be performed to demonstrate the existence of adequate margin when the fracture toughness requirements of Appendix G to 10 CFR 50 are not met.
Our letter L-83-548, dated November 1, 1983, committed to provide such an analysis for Turkey Point Unit 4.
Please find attached the subject analysis.
The results of the analysis demonstr ates that suitable margins of safety were maintained for projected end of life fluence, as well as at least an additional eight full power years.
Consequently, the analysis demonstrates that irradiation danage to the reactor vessel of Unit 4 does not limit the normal operating peak pressure below its current limits for the "upper shelf" portion of the pressure-temperature curve.
Due to the proprietary nature of the subject
- analysis, we have attached an application for wi.thholding the information from public disclosure in accordance with 10 CFR 2.790.

2.
He is tho president of FPDC',
and he has ezecuted this Applioation for Withholding From Public Disolosure and this Affi'davit with the

submittod, together
<<ith this Affidavit'nd Applioation for.Withholding From Public Disclosuro, is the sole and ezcluslve property of FPDC'.
4.
The methodology used to pex'form the analysis in the
.subject ropoxt was developod solely at 'the ezpense of FPDC.
S.
The methods of analysis used are proprietary to FPDC and have not been disolosed to the
,public, or to Florida Power and'Light Company, ezcept as provided in Paragraph 7 below.
6.
The development of certain of the methods of analysis involving the techniques usod in this report aro not published elsewhere in the literaturo.

FPDC is presently in a very strong oompetitive position beoause of its exclusive.knowledge:.of these methods of analysis and disclosuro of information in the subjeot report would irreparably damage tho oompotitive position of FPDC.
9.
Florida Power and Light Company has not paid fees equivalent to the cost of development of teohnology usod in px'eparation of the subject zoport.
