| Title | Failure to Adequately Lubricate the 1B Residual Heat Removal Cooler Damper |
| Description | An NRC-identified Green NCV of TS 5.4.1a, Procedures, was identified for the failure of the licensee to follow the procedure to properly lubricate the 1B RHR room cooler damper The licensee lubricated the damper and returned the room cooler to operable, and entered this issue into the CAP as NCR 607514. The inspectors determined that the failure of the licensee to properly lubricate the 1B RHR room cooler damper in accordance with Procedure 0PM-DMP500 was a performance deficiency. The finding was more than minor because it was associated with the human performance attribute of the Mitigating Systems Cornerstone and affects the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to lubricate the 1B RHR room cooler damper resulted in a failure of the cooler fan and damper, and the inoperability of the 1B RHR train. Using IMC 0609, Appendix A, issued June 19, 2012, the SDP for Findings At-Power, the inspectors determined the finding was of very low safety significance (Green) because the finding did not affect the design or qualification of a mitigating SSC, the finding did not represent a loss of system and/or function, the finding did not represent an actual loss of a function of a single train for greater than the TS allowed outage time, the finding did not represent an actual loss of a function of one or more non-TS trains of equipment, and did not screen as potentially risk-significant due to a seismic, flooding, or severe weather initiating event. The finding has a cross-cutting aspect in the area of human performance associated with the work practices attribute because the licensee did not define and effectively communicate expectations regarding procedural compliance to Procedure 0PM-DMP500 and personnel did not follow this procedure. |
