8 Report No.: 50-302/77-111E

!  :. Facility: Crystal River Unit #3

) 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 l

. Designation of Apparent Cause:' .

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

. Analysis of Occurrence: I

{ 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.

, I 4'

. Corrective Action: -

_ 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.
