CAUSE DESCRIPT1CN AND CCRRECTIVE ACTICNS h

, t i l o l [ Probable cause of this event is the CRD inner filter becoming detached. CRD J-3 was l

!i i ;i 1 l tecoupled, retested and will be overhauled at the next refueling outage. Continued 1

g performance of the inner filter pull test during overhaul should prevent recurrence.
