| Title | Failure to Maintain Shutdown Margin Calculation Procedure to Cover Certain Mispositioned Control Rod Events |
| Description | A self-revealing, Green NCV of TS 6.8.1, Procedures and Programs, as described in Regulatory Guide 1.33, Revision 2, February 1978, was identified when PSEG did not maintain procedure SC.RE-ST.ZZ-0002, Shutdown Margin Calculation, to cover certain mispositioned control rod events. Consequently, PSEG performed an unnecessary rapid boration, and a subsequent manual reactor trip, in response to a control rod drop event on January 31, 2014. PSEG entered this in their corrective action program (CAP), implemented compensatory measures for calculating shutdown margin, performed an apparent cause evaluation, and initiated actions to correct the cause of the problem, extent of condition, and extent of cause. The issue was more than minor because it was associated with the procedure quality attribute of the initiating events cornerstone, and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the finding resulted in an unnecessary rapid boration and a manual reactor trip. Using IMC 0609, Attachment 4, Initial Characterization of Findings, and IMC 0609, Appendix A, The SDP for Findings At- Power, the inspectors determined that this finding was of very low safety significance (Green) because it did not cause the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition. The inspectors determined that this finding had a cross-cutting aspect in the area of Human Performance, Procedure Adherence, because reactor engineering did not follow procedure HU-AA-1101, Change Management, when performing a procedure change in response to TB 13-5. Specifically, licensed operators perform and train on shutdown margin (SDM) calculations, but were not included in the SDM procedure change process as identified by PSEG in their ACE [H.8.] |
