Title | Did Not Comply with Technical Specification Requirements While Starting Reactor Coolant Pumps |
Description | The inspectors identified an NCV of Technical Specifications (TS) 3.4.5, RCS Loops Mode 3, because Constellation did not comply with the required starting conditions for reactor coolant pumps (RCPs) during several plant startups on Unit 1. The inspectors identified a discrepancy between the RCP starting requirements described in the operating instructions (OI) and the RCP starting requirements listed in the TS for loop operability. Specifically, the OI did not provide operators with adequate procedural guidance to meet the Mode 3, 4, and 5 TS RCP starting requirements prior to starting RCPs. Constellation entered this issue into their corrective action program (CAP) for resolution. The immediate corrective actions included revising OI-1A, Reactor Coolant System and Pump Operations, to ensure that the TS starting conditions are met prior to starting any RCPs. This finding is more than minor because it is associated with the procedure quality attribute of the Initiating Events cornerstone and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, starting a RCP while not meeting the starting requirements could cause a pressure transient and lift a pressurizer PORV. The inspectors determined that the finding is of very low safety significance because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions will not be available. This finding has a cross-cutting aspect in the area of human performance because Constellation did not provide complete, accurate, and up-to-date procedures that were adequate to assure nuclear safety. Specifically, OI-1A included requirements that were contrary to the TS and led to the operators failure to comply with the TS when starting RCPs (H.2.c per IMC 0305) |
