g7 TrLce=o%t. Anga 704 Sec. Peoowevion 373-4083 Mr. James P. O'Reilly, Director U. S. Nuclear Regulatory Commission Suite 1217 230 Peachtree Street, Northwest Atlanta, Georgia 30303 RE: Oconee Nuclear Station Docket Nos. 50-269, -270, -287

Dear Mr. O'Reilly:

Pursuant to the requirements of Oconee Nuclear Station Technical Specifi-cation 6.6.2.2.a. this report is submitted describing a condition in which measured iodine 131 levels exceeded 10pci/l in individual milk samples.

On October 26, 1977, analytical results of a milk sample collected on October 5, 1977 were reviewed. A summary of the pertinent results of -

these analyses is given below:

Sample Location I-131 Activity (pCi/ liter) 002.1 Five miles West of 19 1 1  !

site on Highway 183 This observed value is comparable with concentration of iodine 131 seen in other parts of South Carolina by state officials and other power companies. The results were apparently due to the September 17, 1977 Chinese nuclear test. The observed values were not a result of a plant related release.

Very truly yours, l
