Title | Failure to Provide Adequate Acceptance Criteria |
Description | The team identified a Green non-cited violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to provide adequate acceptance criteria for bearing oil level in its residual heat removal pump motors. The team identified two examples of this violation, one of which resulted in pump bearing oil being lowout- of-specification. After identification of this performance deficiency, operations management issued an Operations Shift Order to ensure equipment operators appropriately verified bearing oil levels. The failure to provide adequate acceptance criteria for an activity affecting quality was a performance deficiency. The performance deficiency was more than minor because it adversely affected the human performance attribute of the mitigating systems cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events. Using Inspection Manual Chapter 0609, Appendix A, the team determined that the finding was of very low safety significance because it did not result in the loss of operability or functionality of a safety-related system or train. The finding had a cross-cutting aspect in the corrective action program component of the problem identification and resolution crosscutting area because the licensee had failed to implement a corrective action program with a low threshold for identifying issues to ensure that an issue potentially affecting nuclear safety was promptly identified and fully evaluated. |
