ATTACllMENT (1) l IIYDROGEN ANALYZER SPECIAL REPORT We submit this Special Report concerning an inoperable Hydrogen Analyzer as required by Technical Specification 3.6.5.1, Action a.l.
J l
ACTION TAKEN On April 3,1995, the 21 Emergency Diesel Generator (EDG) was removed from service for maintenance.
Removal of the 21 EDG from senice also removes one channel of the liydrogen Analyzer, (OAE6519) from senice since the channel was no longer backed by an alternate power source. The maintenance required to return the 21 EDG to senice was not completed by May 3,1995 at which time the Action Statement for returning the liydrogen Analyzer channel to senice expired. Following completion of repairs to the 21 EDG on May 4,1995, the Ilydrogen Analyzer was returned to senice. At no time during the period of May 3 to May 4,1995 was the other channel of the Ilydrogen Analyzer (OAE6527) inoperable.
CALISES OF INOPERAHILITY The cause of the inoperability is the removal of the 21 EDG from service for maintenance. The maintenance on the 21 EDG required greater than thirty days to complete. An Emergent Technical Specification change was approved on May 2,1995 which allowed the Control Room Ventilation system inoperability period to be extended to 45 days. Ilowever, an emergent Technical Specification change for the Ilydrogen Analyzer was not pursued.
PLANS AND SCIIEDULE FOR RESTORING Tile SYSTEM TO OPERABLE STATUS Following completion of repairs to the 21 EDG on May 5,1995, the flydrogen Analyzer was returned to senice.
