A self-revealing Green non-cited violation … A self-revealing Green non-cited violation (NCV) of Technical Specification 5.4, Procedures, was identified when an automatic recirculation pump runback occurred after improper operations of the Unit 2 master feedwater controller PF push button. The licensee restored compliance when the crew responded to the runback using approved procedures, and restored reactor water level to the correct setpoint. The violation was entered into the licensees corrective action program as condition report (CR) 759497. Failure to operate the Unit 2 master feedwater controller, 2C32-R600, in accordance with plant procedures on January 17, 2014, was a performance deficiency. This performance deficiency was more than minor because it is associated with the human performance attribute of the initiating events cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability during power operations. Specifically, the performance deficiency directly resulted in an unplanned transient when plant systems automatically reduced reactor power. The inspectors screened this finding using IMC 0609, Appendix A, The Significant Determination Process (SDP) For Findings At-Power , dated June 19, 2012. The finding screened as Green per Section B. of Exhibit 1, Initiating Events Screening Questions, because the finding did not cause a reactor trip and the loss of mitigation equipment, a high energy line-break, internal flooding, or a fire. Inspectors determined the finding had a cross-cutting aspect of avoid complacency of the human performance area because the operator did not implement the error reduction tool (reading the placard below the controller) prior to performing an action.controller) prior to performing an action. +
