| Title | Licensee-Identified Violation |
| Description | A licensee identified, Green NCV of Technical Specifications (TS) 3.0.4.a was identified for FENOCs meet all Technical Specification Table 3.3.2-1 requirements to enter mode 3 during reactor startup following a refueling outage on Unit 2. Specifically, while testing turbine trip relays during, two trains of turbine trip relays were inoperable which requires all feedwater lines to be isolated and deactivated. The licensee failed to ensure that the feedwater lines were appropriately isolated and deactivated prior to entering mode 3. This finding is more than minor because it is associated with the transient initiator contributor attribute of the initiating events cornerstone and adversely impacted the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during plant startup. The inspectors evaluated the finding using Exhibit 2, Initiating Events Screening Questions worksheet in Appendix A of IMC 0609, Significance Determination Process. The inspectors determined this finding was not a design qualification deficiency resulting in a loss of functionality or operability, did not represent an actual loss of safety function of a system or train of equipment, was not potentially risk-significant due to a seismic, fire, flooding, or severe weather initiating event, did not affect reactivity control systems, and did not involve the fire brigade. Therefore, inspectors determined the finding to be of very low safety significance (Green). |
