| Title | Failure to Correctly Implement Chemical and Volume Control System Water Transfer Procedure |
| Description | The inspectors identified a self-revealing NCV of Technical Specification (TS) 5.4.1.a, Procedures, when an auxiliary operator (AO) did not correctly implement procedure S-7M, Transferring Refueling Water Storage Tank to Any Chemical and Volume Control System Holdup Tank (HUT), Revision 000, and close valve V-8661, Spent Fuel Pool (SFP) Recirculation Pump \'B\' Discharge Isolation Valve, as specified by step 5.1.21. As a result, an estimated 3,000 gallons of water was inadvertently transferred from the SFP to the \'B\' and \'C\' HUTs which caused the \'B\' SFP pump to automatically trip, and the SFP level to decrease an estimated 5 inches. Ginna implemented several corrective actions including a requirement for operators to conduct a pre-job brief before transferring water with marked-up system prints showing the intended flow path and water transfers are to be observed by a senior reactor operator or a shift technical advisor. Ginna entered this issue into their corrective action program (CAP) for resolution. This finding is more than minor because it is associated with the Initiating Events Cornerstone and affected the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors determined that the finding was of very low safety significance (Green), because the finding did not increase the likelihood of a loss of reactor coolant system (RCS) inventory, degrade the ability of Ginna to terminate a leak path or add RCS inventory when needed , nor degrade the ability to recover residual heat removal. This finding has a cross-cutting aspect in the area of human performance because operators did not adhere to the procedural requirements outlined in S-7M and close valve V-8661 prior to initiating the water transfer (HA.b per IMC 0305) |
