| Title | Failure to Follow the Requirements of the Boric Acid Program |
| Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, for the licensees failure to follow procedure STA-737, Boric Acid Corrosion Detection and Evaluation, Revision 5. Specifically, the licensee did not track all boric acid leaks until they were repaired or cleaned as required by Procedure STA-737. The licensee entered the finding into the corrective action program as Condition Report CR-2011-004625. The licensees failure to follow the requirements of Procedure STA-737 was a performance deficiency. The finding is more than minor because, if left uncorrected, the issue would have the potential to lead to a more significant safety concern. The finding is associated with the procedure quality attribute of the initiating events cornerstone and affected the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Using Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to have very low safety significance because the finding did not result in exceeding the technical specification limit for any reactor coolant system leakage and did not affect other mitigation systems resulting in a total loss of their safety function. The finding has a human performance crosscutting aspect associated with the work control component, because the licensee did not appropriately coordinate work activities by incorporating actions to address the impact of changing the schedule to repair boric acid leaks. |
