| Title | Failure to Follow TS 5.5.2 Implementing Procedures |
| Description | The inspectors identified a non-cited violation of Technical Specification (TS) Section 5.5.2, Primary Coolant Sources Outside Containment, because the licensee was not following procedures which implemented TS 5.5.2. The licensee\'s corrective actions included: performing Operability Evaluation 11-001; quantifying the leakage from check valve 3-1201-306 three times per week, and repairing the leak on March 10, 2011. The inspectors determined the finding was more than minor because it was similar to IMC 0612, Appendix E, example 2.h, in that multiple examples were identified where non-licensed operators failed to identify that the leakage was increasing. This resulted in the failure to implement the TS 5.5.2 program. The inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 - Initial Screening and Characterization of Findings, Table 4a for the Barrier Integrity Cornerstone, because portions of the barriers between the primary and secondary containment were degraded. The inspectors were able to answer No to all four questions on Table 4a under the Barrier Integrity Cornerstone. Therefore, the finding was determined to be of very low safety significance. This finding has a cross-cutting aspect in the area of Human Performance, Work Practices because the licensee did not ensure supervisory and management oversight of work activities such that nuclear safety was supported. Specifically, non-licensed operators were expected to identify an increase in system leakage without adequate oversight to do so (H.4(c)). |
