| Title | lnadvertent Auxiliary Feedwater Start during Steam Generator Water Level Instrument Adjustments |
| Description | A Green, self-revealing non-cited violation (NCV) of TS 5.4.1, Procedures, was identified in that technicians inadvertently caused an auxiliary feedwater actuation when the plant was shutdown for refueling. Specifically, the procedure used to inject simulated steam generator water signals was inadequate, which resulted in the technicians erroneously inserting two-of-three (213) Low-Low level signals to the SGs and causing actuation of auxiliary feedwater. This issue was entered into the licensee\'s corrective action program under CR 1 1-90528. Traditional enforcement does not apply because the issue did not have an actual safety consequence or the potential for impacting NRC\'s regulatory function, and was not the result of any willful violation of NRC requirements. The finding is more than minor because it is similar to example 4.b in IMC 0612, Appendix E. The inspectors performed a Phase 1 SDP evaluation in accordance with IMC 0609, Appendix G, Attachment 1, Checklist 2 PWR Cold Shutdown Operation: RCS Closed and SGs Available for DHR (Loops Filled and Inventory in Pressurizer) Time to Boiling Less than 2 Hours. There was no loss of control, and all mitigating capabilities were available, therefore a Phase 2 quantitative assessment was not required and the issue screened to Green (very low safety significance). The cause of this NCV relates to the cross-cutting aspect of Human Performance, Work Control, in that FENOC personnel did not appropriately coordinate work activities by incorporating actions to address the need to communicate, coordinate and cooperate with each other during activities in which interdepartmental coordination is necessary to assure plant and human performance. |
