| Title | Failure To Review Motor Operated Valve (MOV) Data and Complete Analysis of the Data in a Timely Manner |
| Description | The team identified a Green, non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, which states, in part, Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Specifically, between November 2013 and April 2014, the licensee did not follow Procedure EDP-ZZ-01114, Motor Operated Valve Program Guide, Step 6.3.1, as they had not completed a test report for Motor Operated Valve BNLCV0112E, Centrifugal Charging Pump Suction from Refueling Water Storage Tank Isolation Valve, within 60 days, as required by the procedure. The results of the analysis, when completed, were non-conservative with the measured stem coefficient increasing from the design value of 1.5 to approximately 1.7, decreasing the available torque margin from approximately 23 percent to 7 percent. In response to this issue, the licensee confirmed that all of the values in the Performance Report for BNLCV0112E were accurate and that the valve would still function. The licensee also initiated a work order to restore the valve margin. The licensee determined that several other diagnostic test results had not been analyzed in a timely manner; and evaluated these results which were found to be acceptable. This finding was entered into the licensee's corrective action program as Callaway Action Requests (CARs) 201402987 and 201402992. The team determined that the failure to follow Procedure EDP-ZZ-01114 for the timely evaluation of motor operated valve test data was a performance deficiency. This finding was more than minor because if left uncorrected, it would lead to a more significant safety concern. Specifically, not reviewing motor operated valve data and completing the analysis of the data in a timely manner could result in safety-related motor operated valves not being able to meet their safety function. In accordance with Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated June 19, 2012, Exhibit 2, Mitigating Systems Screening Questions, the issue screened as having very low safety significance (Green) because it was a design or qualification deficiency that did not represent a loss of operability or functionality; did not represent an actual loss of safety function of the system or train; did not result in the loss of one or more trains of non-technical specification equipment; and did not screen as potentially risksignificant due to seismic, flooding, or severe weather. This finding had a cross-cutting aspect, pertaining to resources, in the area of human performance, because licensee leaders failed to ensure that personnel, equipment, procedures, and other resources are available and adequate to support nuclear safety [H.1]. |
