| Title | Failure to Correct Discolored Boric Acid Deposits |
| Description | The inspectors identified a cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, for failure to take action to stop leakage from the base of the refueling water storage tank or evaluate the leakage and wastage for acceptability. Specifically, the licensee did not take actions to prevent recurring discolored boric acid deposits for approximately 11 years. Failure to correct leakage from the refueling water storage tank base was the subject of a noncited violation in NRC Inspection Report 05000482/2007006. This issue was entered into the licensee\'s corrective action program as Condition Report 22866. The failure to implement corrective actions for the refueling water storage tank leakage was a performance deficiency. The inspectors determined this issue impacted the Mitigating Systems Cornerstone and was greater than minor because if left uncorrected, the failure to correct the presence of boric acid leakage could become a more significant safety concern in that continued wastage could impact tank operability. Using the Phase 1 worksheets in Inspection Manual Chapter 0609.04, Significance Determination Process, the finding was determined to have very low safety significance because it did not result in a system or component being inoperable and it did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. The inspectors identified a crosscutting aspect in the area of human performance associated with resources. Specifically, Wolf Creek did not maintain long-term plant safety minimizing corrective maintenance deferrals and this long-standing equipment issue H.2.c] (Section 1R05) |
