| Title | Failure to Perform Adequate Post Trip Review |
| Description | The inspectors identified a Green finding for the failure to adequately implement the post trip review procedure following a reactor trip caused by low steam generator water levels on March 2, 2010. Specifically, Wolf Creek\'s post trip evaluation was not adequate because it failed to identify or evaluate anomalous equipment performance associated with the main feedwater pump that caused the trip. Additionally, the inspectors determined that the Wolf Creeks post trip review failed to identify that some aspects of operator response to the trip of the main feedwater pump were not in accordance with station procedures. Wolf Creek evaluated the individual issues and deficiencies listed above and entered them into the corrective action program as Condition Reports 23932, 23966, 24043, 23982, and 23981. This finding was greater than minor because the information omitted from the posttrip review was associated with the human performance attribute of the mitigating systems cornerstone and affected the cornerstone objective to ensure the availability, reliability and capability of systems that respond to initiating events. Using Manual Chapter 0609.04, Phase 1 - Initial Screening and Characterization of Findings, this finding was determined to be of very low safety significance since the finding does not represent a loss of system safety function, nor does the finding represent actual loss of safety function for single train for a greater time than permitted by technical specifications. This finding had a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program component because Wolf Creek failed to fully evaluate plant computer data and operator statements associated with the March 2, 2010, reactor trip |
