ENCLOSURE BELLEFONTE NUCLEAR PLANT UNIT 2 VALVE FLOODED IN REACTOR BUILDING NORMAL SUMP - UNIT 2 BLRD-50-439/83-56 10 CFR 50.55(e)
NCR 2549 FIRST INTERIM REPORT Description of Deficiency The motor-operator of valve (2WL-IFCV-068-B) in the liquid waste system was damaged by flooding of the reactor building normal sump tank room. The flooding was initially attributed to a system flush. An investigation, however, was made into the apparent cause of this deficiency by Bellefonte's Division of Construction (CONST) and revealed that other conditions could have caused the flooding instead of a system flush. An additional investigation is being performed to determine the apparent cause of this deficiency.
Interim Progress The valve motor operator will be disconnected and sent to Bellefonte's electric shop for cleanup and inspection. If the motor operator cannot be refurbished onsite, the motor operator will be returned to the vendor (Limitorque) for rework.
