Title | Failure to Follow Foreign Material Exclusion Requirements in Reactor Vessel Maintenance Procedures |
Description | A self-revealing non-cited violation (NCV) of Unit 2 Technical Specification 6.8.1.a was identified for the licensees failure to follow the requirements in reactor vessel maintenance procedures, to exclude foreign material from the reactor coolant system (RCS) during refueling outage activities. The licensee entered the issue in the corrective action program as action request 1957565. Corrective actions included evaluation of the foreign object damage, and revision of foreign material exclusion (FME) controls in outage maintenance procedures. The performance deficiency was more than minor because if left uncorrected, it had the potential to lead to more significant safety concerns. Specifically, the failure to follow FME controls in maintenance procedures had the potential to lead to the introduction of foreign material in the RCS, which could result in degradation of RCS components, such as the fuel cladding, RCS pressure boundary cladding, and steam generator (SG) tubes. The inspectors screened this finding utilizing IMC 0609 Attachment 4, Initial Characterization of Findings, dated June 19, 2012, and IMC 0609 Appendix A, The Significance Determination Process for Findings at Power, dated June 19, 2012. The finding screened as Green using Exhibit 1, Section D, Initiating Events Screening Questions, screening question 2, because the finding did not result in a condition where one or more SGs violated accident leakage performance criterion (i.e., did not involve degradation that would exceed the accident leakage performance criterion under design basis accident conditions). The inspectors determined this performance deficiency had a resources crosscutting aspect (H.1) in the human performance area, because the licensees administrative procedure for FME practices, MA-AA-101-100, was inadequate to support nuclear safety, in that it allowed for a less conservative approach to FME in the reactor cavity. |
