| description = A URI was identified by the inspectors for performance deficiencies (PD) associated with the reactor coolant pump (RCP) motor oil collection system. On November 28, 2012, during containment walkdowns the inspectors identified three PDs regarding failures to comply with licensees fire protection program requirements associated with 10 CFR 50, Appendix R, Section O, for a RCP motor oil collection system. Specifically, the inspectors identified (1) a split in the sealing boot for the B RCP motor oil cooler enclosure, (2) a design deficiency on all three RCP motor oil lift pump enclosures, and (3) a design deficiency on all three RCP motor exhaust ductwork components. The design deficiency on the oil lift pump enclosure involves a small rectangular door with no latch that can be opened to view the respective oil pressure gauge. A leak at the gauge fitting would allow pressurized oil at approximately 1200 psig to push the door open and release oil from the enclosure. The design deficiency on the motor exhaust ductwork involves the collection of oil mist from leakage internal to the motor which then leaks out of the ductwork flange connections as evidenced by observed drips of oil at the affected joints. The inspectors also observed white silicone caulking at these joints where the licensee had attempted to prevent leakage. The licensee initiated CR-12-05736 and CR-12-05756 to address these deficiencies. Pending completion of additional inspection and review of information to determine if the PD is more than minor, this is identified as URI 05000395/2012005-01, Nonconformance of RCP Motor Oil Collection System with the Fire Protection Program | | description = A URI was identified by the inspectors for performance deficiencies (PD) associated with the reactor coolant pump (RCP) motor oil collection system.
