Report Number:

81-53/03L Report Date:

July 31, 1981 Occurrence Date:

7-1-81 Facility:

Salem Generating Station, Unit 2 Public Service Electric & Gas Company Hancocks Bridge, New Jersey 08038 IDENTIFICATION OF OCCURRENCE:

Missed Surveillance - Containmenu Air Lock.

This report was initiated by Incident Report 81-229.

CONDITIONS PRIOR TO OCCURRENCE:

Mc3e 1 - Rx Power 30% - Unit Load 220 MWe DESCRIPTION OF OCCURRENCE:

On July 1, 1981, after a Unit 2 outage period in which both the inner and outer containment air lock doors were open, containment integrity was established without performing the surveillance procedure as reqaired by technical specification 4.6.1.3.b.

DESIGNATION OF APPARENT CAU3E OF OCCURRENCE:

Personnel error.

The operators overlooked the surveillance requirement for Unit 2 containment air lock because it is new.

They didn't realize it was different than the requirement for Unit 1, which calls for a leakage test to be performed every 6 months.

The previous airlock test was well within that time period, having been satisfactorily performed on the 130' elevation air lock on April 13, 1981, and the 100' elevation air loch on April 30, 1981.

ANALYSIS OF OCCURRENCE:

Technical specification 4.6.1.3.b requires:

Each containment air lock sha31 be demonstrated operable prior to establishing containment integrity, if opened when containment integrity was not required.

CORRECTIVE ACTION

When it was discovered that the Unit 2 containmert air locks had a new surveillance requirement, and it had been missed, the surveillance was completed immediately.

All personnel involved were counseled on the difference between Unit 1 and Unit 2 containment air lock surveillance and their importance.
