| Title | Failure to Follow Operations Procedures |
| Description | The team identified a non -cited violation of Technical Specification 5.4.1.a , Procedures, for the licensees failure to implement procedures required by Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Specifically, contrary to procedures , on September 23, 2016, operations personnel failed to verify adequate plant service water flow to the alternate decay heat removal heat exchangers while placing the system in service . The licensee implemented corrective actions which included high intensity training to improve nuclear worker behaviors and clarifying the directions in the procedure. The licensee entered this issue into the corrective action program as Condition Report CR- GGN -2016- 08333. The failure to implement procedures , as required by Technical Specification 5.4.1. a, was a performance deficiency. This performance deficiency was more than minor, and therefore a finding, because , if left uncorrected, the failure to implement procedures as required by Technical Specification would have the potential to lead to a more significant safety concern. Using Inspection Manual Chapter 0609, Appendix G, Shutdown Operations Significance Determination Process , and Inspection Manual Chapter 0609, Appendix G, Attachment 1, Shutdown Operations Significance Determination Process Phase 1 Initial Screening and Characterization of Findings, the team determined that the finding was of very low safety significance (Green ) because it did not affect the design or qualification of a mitigating system structure, system , or component and did not directly prevent the alternate decay heat removal system from maintaining its functionality. The team identified a cross -cutting aspect the area of human performance, challenge the unknown, because individuals failed 4 to stop when faced with uncertain conditions and risks were not evaluated and managed before proceeding [H.11]. |
