ANALYSIS OF OCCURRENCE:

Technical Specification 3.3.3.1 requires:

Action 24 l

With the number of channels operable less than required by the minimum channels operable requirement, comply with the l

Action requirements of Specification 3.4.7.1.

Action 25 With the number of channels operable less than required by j

the minimum channels operable requirement, comply with the l

Action requirements of Specification 3.9.9.

l Technical Specification 3.4.7.1 requires:

i With only two of the required Leakage Detection Systems j

operabic, operation may continue for up to 30 days provided i

grab samples of the containment atmosphere are obtained and analyzed at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when the required Gaseous i

and/or Particulate Radioactivity Monitoring System is in-operable.

i Technical Specification 3.9.9 requires:

At 1435 hours0.0166 days <br />0.399 hours <br />0.00237 weeks <br />5.460175e-4 months <br /> the APD Pump was removed from the normal flow lineup and placed in the backup flow lineup.

Adequate flow was reestablished, returning the APD to operable status, and Action Statement 3.3.3.1 Actions 24 and 25 was terminated.

All requirements of Action Statements 3.4.7.1 and 3.9.9 were met.

Subsequently, it was discovered that valve 2VC908, which 4

should have been open in the normal lineup, was shut.
