Title | Failure to Clean the Safety Related Pump Pit Once per Two Cycles |
Description | An NRC identified finding (FIN) was identified for the licensees exceeding the maximum allowed periodicity for inspecting and cleaning the Residual Heat Removal Service Water (RHRSW) pump pit per Raw Water Corrosion Program procedure (NPG-SPP 9.7.3). This finding was determined to be more than minor because, if left uncorrected, the failure to maintain the intake pump pit cleaning would have had the potential to lead to a more significant safety concern in that, it could lead to fouling of safety related coolers. challenging the heat exchanger heat removal function. The finding is associated with the Mitigating Systems cornerstone. Using IMC 0609 Appendix A, Exhibit 2, the finding screened as green because the finding did not represent an actual loss of function of a single train for greater than its technical specification allowed outage time and did not represent an actual loss of function of one or more non-technical specification equipment for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The cause of this finding was associated with the human performance area, resources component, cross cutting aspect of maintaining long term plant safety by maintenance of design margins and minimizing preventative maintenance deferrals due to the licensee not allocating resources to clean the intake pump pits. |
