| Title | Failure to properly perform a procedure results in damage to an RHR pump |
| Description | A self-revealing, non-cited violation (NCV) of Technical Specifications 6.8.1.a, Procedures, was identified when operators did not properly align the RHR system from shutdown cooling mode to injection mode. As a result, the 4A RHR pump was left running with no suction source causing a failure of the pump mechanical seal and minor flooding in the Unit 4, A RHR pump room. The pump was not available for either injection or shutdown cooling operations until the seal was replaced. The issue was documented in the corrective action program as AR 1644427 and a root cause investigation was initiated. Failure to properly align the RHR system to the injection lineup was contrary to plant procedures and was a performance deficiency. The finding is more than minor because it is associated with the equipment performance attribute of the Mitigating System Cornerstone and resulted in damage to an RHR pump. The finding was screened using IMC 0609, Appendix A, Phase 1, and because there was no loss of safety function with the alternate RHR pump remaining operable, the finding was determined to be of very low safety significance. The finding affected the cross-cutting area of Human Performance, Work Practices because personnel did not adequately implement error prevention techniques, such as pre-job briefings, self and peer checks, and proper documentation of activities |
