1..

Report Date:

21 September 1977 Occurrence Date:

January 1,- July 31, 1977 (discovered 6 September 1977) '

Identification of Occurrence:

i Environmental samples were not analyzed using procedures which provided LLD's equal j

to or less than those required by the Environmental Technical Specifications.

j

..-Conditions Prior to' Occurrence:

NA Description of Occurrence:

j.

The following samples had LLD'n greater than that required by ETS for the~ dates indicated below:

'l l-j Designation of Apparent Cause:'

Inadequate ' techniques, procedures, and/or equipment to achieve the requ' ired LLD's i

Analysis of Occurrence:

{

The average concentrations of the nuclides whose LLD's were greater. than ETS for

~l each Sample S,tation were below the preoperational 95 percentile concentration.

Therefore, there has been no undetected damage to the environment adjacent to Crystal River Unit f3.

Corrective Action:

4'

_ Analysis procedures are being revised to allow for longer count -times and better 1

calculations of. background counts. These will lead to LLD's which should be below the ETS' limit.

)-

.- Failure Data:

This is the first report for this type.of occurrence.
