| Title | Inadequate Corrective Actions to Address an Adverse Trend in the 2R1B-2 Radiation Monitor |
| Description | The inspectors identified an NCV of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, associated with PSEG failing to adequately trend an adverse condition and initiate effective corrective actions to address declining performance. Specifically, PSEG did not take adequate corrective actions to address an adverse trend in radiation monitor channel spiking caused by defective detector foil. As a result of these ineffective corrective actions, on April 20, 2013, a spike of the 2RIB channel 2 radiation monitor (2RIB- 2) unintentionally resulted in an unanalyzed post-accident dose analysis condition for the Salem common control room (CR). PSEG has entered this issue into their CAP as Notification 70154084. The PD was determined to be more than minor because it affected the Human Performance attribute of the barrier integrity cornerstone to maintain the radiological barrier functionality of the CR post-accident. The PD was also similar to IMC 0612, Appendix E, example 3.i, in that, the CR post-accident dose analysis calculation was required to be reperformed by PSEG to assure the post-accident dose analysis limits were not exceeded. The finding is of very low safety significance (Green) per IMC 0609, Attachment 4, Phase 1, Appendix A, Exhibit 3 Barrier Integrity Screening Questions, because it only represented a degradation of the radiological barrier function provided for the control room. The finding had a cross-cutting aspect in the area of Problem Identification and Resolution (PI&R), CAP, because PSEG did not adequately trend and assess information from the CAP to identify programmatic and common cause problems. Specifically, PSEG did not take adequate corrective actions to address an adverse trend in the 2R1B-2 detector foil replacement and as a result of these ineffective corrective actions, on April 20, 2013, a spike of the radiation monitor unintentionally resulted in an unanalyzed post-accident dose analysis condition for the Salem common CR. |
