Oconee Nuclear Station tr 3/

Docket Nos. 50-269, -270 and -237 Y/ gi \\/g/

Dear Mr. Moseley:

The Oconee Nuclear Station Semiannual Report, for the period ending December 31, 1974 was transmitted to you by my letter of February 28, 1975.

Subsequent to that submittal, it has been determined that certain data presented in Appendix A.Section V are incorrect due to the malfunction of a temperature recording device at the F-awee Hydro

(

Station. However, a second system for monitoring the temperature was operating correctly during this period.

Please find attached forty copics of replacement pages 43-48 for Appendix A,Section V.

Very truly yours,

[

Tr-A. C. Thies
