Re: Oconee Nuclear Station Docket Nos. 50-269, -270, -287

Dear Sir:

.p ;,,,,,,,,,

,,,, j.

Pursuant to 10CFR50.36a and Oconee Technical Specifications 6.6.1.2(c),

reports were submitted on August 19, 1976 and February 23, 1977 concern-ing radioactive effluents released from Oconee Nuclear Station for the first six months of 1976 and the last six months of 1976, respectively.

During review of this data, certain errors in isotope identification have been discovered. Please find attached copies of the following sheets which correct these errors.

1.

Summary of liquid radioactive effluent releases for the first six month period transmitted by our letter of August 19, 1976. Under item 7, the isotope designated as Agl98m is corrected to read Ag108m.

2.

Summary of liquid radioactive effluent releases for the first and second six month period transmitted by our letter of February 23, 1977. Under item 7 the isotope designated as Kr87 is corrected to read Ag108m.

Verypr'ulyyours,
