| Title | Inadequate Design Control of Emergency Diesel Generator Speed Switch |
| Description | The inspectors identified a Green non-cited violation (NCV) of Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion III, Design Control, because PSEG did not adequately provide for verifying or checking the adequacy of design by the performance of design reviews. Specifically, PSEGs equivalent change package (ECP) 80112197, did not assure that the design change ECP 80119127 was adequately reviewed prior to approval, which led to the installation of a defective model A-416 speed switch (SS), and subsequent failure of the D emergency diesel generator (EDG) to start. PSEGs immediate C/As were to remove the new failed model 416 SS and reinstall the prior model 8 SS. Additionally, PSEG entered this issue into their CAP, performed a causal evaluation, and assigned C/As to address their design change process (DCP) gaps by revising procedures and conducting training.This issue was more than minor because it was associated with the Design Control attribute of the Mitigating Systems cornerstone, and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). In accordance with IMC 0609.04, Initial Characterization of Findings, dated October 7, 2016, and Exhibit 2 of IMC 0609, Appendix A, The SDP for Findings At-Power, dated June 19, 2012, the inspectors determined that this finding is of very low safety significance (Green) because the performance deficiency was not a design or qualification deficiency, did not involve an actual loss of safety function, did not represent the actual loss of a safety function of a single train for greater than its technical specification (TS) allowed outage time, did not represent an actual loss of function of one or more non-TS trains of equipment designated as high safety-significant in PSEGs maintenance rule program (MRP) for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. This finding had a cross-cutting aspect in the area of Problem Identification and Resolution, operating experience (OE), because PSEG did not ensure that the organization systematically and effectively collect, evaluate, and implement relevant internal and external OE in a timely manner. Specifically, PSEG did not effectively collect or review previous Part 21 issues related to the new SS as part of the OE review in their DCP. [P.5] |
