The inspectors identified a finding of very-low safety significance (Green), and an associated (
NCV) of
10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action,for the licensees failure to identify a
condition adverse to quality. Specifically, after receiving and reviewing the
Flowserve 10 CFR Part 21 report, the licensee misunderstood the information provided and failed to identify 36 safety-related valves that were nonconforming. Of these 36 valves, 14 were identified as being susceptible to pin failure based on their
torque setting, 6 of which had open or close safety functions. The licensee captured the inspectors concern in the
CAP as
AR 02212531, and
AR 02212915. In addition, the licensee performed operability evaluations that concluded the affected valves remained
operable.The performance deficiency was more-than-minor because it was associated with the equipment performance attribute of the Mitigating System and Initiating Event cornerstones, and adversely affected the cornerstone individual objectives. Using
IMC 0609, Appendix A, The
Significance Determination Process for Findings At-Power, the finding screened as of very-low safety significance (Green) by answering No to the questions contained in Exhibit 1, and in accordance with Exhibit 2, it did not result in the loss of operability or functionality of
mitigating systems. The team did not identify a cross-cutting aspect associated with this finding because the most significant cause for the error was not reflective of current performance. Specifically, the Part 21 report and associated review by the licensee occurred in February 2013.
