| Title | |
| Description | The inspectors identified a finding of very low significance and NCV of10 CFR 50, Appendix B, Criterion V, for the licensee approving the use of non-quality documents in the absence of approved procedures to modify the normal operation of intermediate range monitor (IRM) 11 and IRM 18. Implementation of this guidance would have resulted in a condition that would not have been in compliance with Technical Specifications. Once identified, the licensee took immediate corrective actions to correct the situation and entered the issue into their corrective action program. The inspectors determined that the performance deficiency affected the cross-cutting area of Human Performance, having decision making components, and involving aspects associated with using conservative assumptions in decision making and adopting requirements to demonstrate that proposed actions are safe in order to proceed, rather than a requirement to demonstrate that it is unsafe in order to disapprove actions. (H.1(b)) The inspectors determined that the finding was more than minor because it impacted the Reactor Safety Mitigating System Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using IIMC 0609, Appendix A, Attachment 1, Significance Determination of Reactor Inspection Findings for At-Power Situations, using the Phase 1 Worksheet for the Mitigating Systems Cornerstone. After answering No to all five questions in the Mitigating Systems Cornerstone column of Table 4a, Characterization Worksheet for Initiating Events, Mitigating Systems, and Barrier Integrity Cornerstones, the inspectors concluded that the finding was of very low safety significance |
