| Title | Failure to Evaluate Changes to Ensure They Did Not Require Prior Approval |
| Description | The team identified a non-cited violation of 10 CFR 50.59, Changes, Tests, and Experiments, associated with the licensees failure to adequately evaluate Modification EC 33464, Replace AK-50 480 V Main and Bus-Tie Breakers With Molded Case Type or Equivalent, to determine if it required prior NRC approval. Specifically, the licensees documented evaluation failed to identify and evaluate new creditable failure modes to determine whether they would have an adverse effect on the 480 Vac electrical distribution system. The licensees corrective action was to revise the evaluation. This issue was entered into the licensees corrective action program as CR 2013-04474 and 2013-16954. The licensees failure to implement the requirements of 10 CFR 50.59 and adequately evaluate changes associated with the electrical distribution system is a performance deficiency. Because this performance deficiency had the potential to impact the NRCs ability to perform its regulatory function, the team evaluated the performance deficiency using traditional enforcement. In accordance with Section 2.1.3.E.6 of the NRC Enforcement Manual, the team evaluated this finding using the significance determination process to assess its significance. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, the finding is determined to have very low safety significance (Green) because it: (1) was not a deficiency affecting the design or qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its Technical Specification allowed outage time, or two separate safety systems out-of-service for longer than their Technical Specification allowed outage time; (4) did not represent an actual loss of function of one or more non-Technical Specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program; and (5) did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding, or severe weather event. Therefore, in accordance with Section 6.1.d.2 of the NRC Enforcement Policy, the team characterized this performance deficiency as a Severity Level IV violation. The team determined that a crosscutting aspect was not applicable to this performance deficiency because the failure to adequately evaluate changes in accordance with 10 CFR 50.59 was strictly associated with a traditional enforcement violation (Section 4OA4). |
