Dear Mr. Moseley:
Pursuant to the requirements of Oconee Nuclear Station Technical Specification 6.6.2.2.c, this report is submitted describing c cor.dition in which measured radiation levels exceed the control level by greater than ten times.
On July 8, 1977 analytical results of thermoluminescent dosimeters in the field from March 22, 1976 to June 28, 1977 were received. A summary of the pertinent results of the radiation levels is as follows:
SAMPLE LOCATION TOTAL mR mR/hr 008 Liberty, S. C. (control) 23
.00978 000.18 West Fence of Restricted Area 945.67
.402 Sample location 000.18 is located well within the exclasion area on the west fence, which isolates the restricted area from the unrestricted area. Location 000.18 is 60 feet from a borated water storage tank (BWST) which, according to unit operation, causes varying radiation levels at location 000.18. Current radiation levels at the BWST are 1 - 10 mR/hr @ contact and at location 000.18 is 0.5 mR/hr. During refueling operations associated with Oconee Unit 1, the area adjacent to the BWST will be monitored, and roped off as necessary, with appropriate warning signs due to the increased level of radiation from the BWST.
The radiation levels at location 000.18 represent exposures for twenty-four hours per day continuing through the quarter. Consequently, even though the radiation,
levels at location 000.18 exceed control levels, these radiation levels do not relate to the exposures of individuals since the area adjacent to the west re-stricted area is occupied for short time periods only as individuals pass the point going to and from a parking lot.
Therefore, the actual exposures of
