| Title | Failure To Provide Adequate Technical Justification For Operability of Containment Spray and Diesel Fuel Oil Systems |
| Description | The inspectors identified multiple examples of a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure of operations personnel to follow station procedures used to perform operability determinations. Specifically, operations personnel failed to provide sufficient technical justification for the reasonable assurance of operability of a degraded condition involving one train of containment spray system and nonconforming conditions associated with diesel fuel oil piping. The inspectors concluded the failure of operations personnel to follow station procedures to perform operability determinations was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it adversely affected the equipment performance attribute of the Mitigating Systems Cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the significance of the issue under the Significance Determination Process, as defined in Inspection Manual Chapter 0609.04, Initial Characterization of Findings, and 0609, Appendix A, The Significance Determination Process (SDP) for Findings at-Power. The inspectors concluded the finding was of very low safety significance (Green) because all questions in Exhibit 2 could be answered in the negative. The inspectors determined that the finding had a consistent process cross-cutting aspect in the area of human performance because the licensee did not use a consistent and systematic process to make decisions (H.13). |
