| Title | Inadequate Evaluation of 480VAC Motor Control Center Design Change |
| Description | A self-revealing Green NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, was identified for PSEGs failure to adequately evaluate a modification to the design change package for replacement buckets on the Class 1E 10B232 480 VAC motor control center (MCC) in accordance with PSEG procedure CC-AA-103-1001, Implementation of Configuration Changes. This resulted in damage to and deenergization of the 10B232 MCC during maintenance activities to install a new replacement bucket on October 28, 2013. PSEGs corrective actions included a full extent of condition inspection of all installed modified MCC buckets and removing instructions to install terminal block screws in future modifications. This issue was more than minor because it was associated with the design control attribute of the Mitigating Systems cornerstone, and adversely affected the cornerstones objective to ensure the availability and reliability of systems that respond to initiating events to prevent undesirable consequences. Because this finding occurred while the plant was shut down, the inspectors used IMC 0609, Appendix G, Shutdown Operations Significance Determination Process, dated February 28, 2005. The inspectors determined the finding to be of very low safety significance (Green) using Checklist 7 of Attachment 1, Boiling Water Reactor Refueling Operation with Reactor Coolant System (RCS) Level Greater Than 23 Feet, because qualitative assessment concluded that PSEG maintained adequate mitigation capability and the event was not characterized as a loss of control. The inspectors determined that the finding had a cross-cutting aspect in Human Performance, Procedure Adherence, because PSEG personnel did not follow site procedures. |
