| Title | Failure to Accomplish Analog Protection Functional Test Per Procedure Instructions |
| Description | A self-revealed finding of very low safety significance and a Non-Cited Violation of 10 CFR Part 50, Appendix B, Criterion V were identified on February 9, 2010, due to operations personnel failing to accomplish Surveillance Procedure (SP) 1003, Analog Protection Functional Test, in accordance with the instructions provided in the procedure. Specifically, operations personnel failed to position the rod bank selector to manual as directed by Step 9.5.1.D of SP 1003. As a result, the control rods automatically responded inward to a simulated change in first stage turbine pressure which resulted in an approximate seven percent reduction in reactor power. Corrective actions for this issue included removing all licensed operators associated with this event from duty pending remediation, reviewing this event and reinforcing the requirements for pre-job briefings and procedure use and adherence with all operations personnel, and reinforcing the expectation to use human performance tools. The inspectors determined that this finding was more than minor because it was associated with the human performance attribute of the Initiating Events cornerstone. In addition, this finding impacted the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. This finding was of very low safety significance because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigating systems equipment or functions would not be available. The inspectors concluded that this finding was cross-cutting in the Human Performance, Work Practices area because operations personnel failed to properly use human error prevention techniques, such as pre-job briefings, self and peer checking, and proper documentation of activities such that work activities are performed safely (H.4(a)).
