3. Report Date: 17 July 1978 4 Occurrence Date: June 1978, (discovered 7/14/78) determined at plant 7/17/78.

5. Identification of occurrence:

Environmental samples were not analyted using procedures which provided LLD's equal to or less than those required by the Environmental Technical Specifications:

6. Conditions Prior to Occurrence:

N/A

7. Description of Occurrence-The following samples had LLD's greater than those required for the dates indicated below: )

Seawater (6 stations) June

( # > ETS) 6 Designation of Apparent Cause:

Natural radiation background may have caused activity La che samples which can re'sult in higher LLD's. Inadequate sample count time may also have contributed to the greater than required LLD's.

l

9. Analysis of Occurrence:

Of the six nuclides whose LLD's were greater than required, the activity associated with all of the nuclides was non-detectable.

10. Corrective Action:

The annual average LLD for I-131 and TH-232 in Seawater is equal to, or less chan,;

that required. No further corrective actions are necessary for the Seawater pathway.

11. Failure Data:

This is the tenth (10th) report for this type occurrence. Refer to:
