| Title | Inadequate Evaluation of a Main Control Room Chiller Design Change |
| Description | The inspectors reviewed a Green self-revealing NCV of Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion III, Design Control, for PSEGs failure to effectively implement the design change process. Specifically, PSEGs design change package (DCP) 4EC-3662 failed to reclassify the purchase classification (PC) of the main control room (MCR) chiller pressure control valve (PCV) positioner from non-safety related (PC4) to safety related (PC1). Because of the incorrectly assigned PC, PSEG did not track the shelf life of replacement positioner diaphragms, which led to the failure of the A MCR positioner on December 20, 2013. PSEGs corrective actions included replacement of the failed positioner and changing the purchase classification for the chiller PCV positioners to safety-related (PC1). Since the implementation of DCP 4EC-3662 in 1997, the DCP procedures have been enhanced to ensure the completion of a purchase class evaluation of procured materials that are implemented in the design change process. The inspectors determined that the performance deficiency was more than minor because it is associated with the design control attribute of the Barrier Integrity cornerstone, and adversely affected the cornerstone objective of maintaining the radiological barrier functionality of the control room. In accordance with Exhibit 3 of NRC IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings at Power, issued June 19, 2012, the inspectors determined that this finding is of very low safety significance (Green) because the performance deficiency represents a degradation of only the radiological barrier function provided for the control room. The inspectors determined that there was no crosscutting aspect associated with this finding because the cause of the performance deficiency occurred more than three years ago, and was not representative of present plant performance. |
