| Title | Failure to Follow Procedure Results in Water Hammer |
| Description | The inspectors identified a non-cited violation of Technical Specification 5.4.1.a for the failure to follow an auxiliary feedwater system operating procedure. As a result, a water hammer occurred on the condensate storage tank makeup reject line. The licensee entered the finding into the corrective action program as Condition Report CR-2012-012539. The finding was more than minor because it was associated with the human performance attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective, in that, it increased the likelihood of those events that upset plant stability and challenge critical safety functions during power operations. Specifically, it resulted in a system water hammer. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, the finding was determined to be of very low safety significance because the finding did not cause a reactor trip and the loss of mitigation equipment. The finding had a human performance cross-cutting aspect associated with resources, in that, the licensee failed to ensure that personnel were adequately trained to perform the activity. |
