| Title | Failure to Perform Functionality Assessments for Degraded and Nonconforming Plant Conditions |
| Description | The inspectors identified a finding of very low safety significance for the licensees failure to follow its procedural guidance to assess the effects of degraded and nonconforming conditions involving plant SSCs not specifically covered by the plants Technical Specifications (TSs) and to correctly document a functionality assessment when the conditions affected functions described in the current licensing basis (CLB). No violation of regulatory requirements was identified because the examples of degraded and/or nonconforming conditions involved non-safety-related plant SSCs. The licensee entered this finding into its CAP to identify a functionality assessment process did not exist within its procedures and to investigate recommended process and procedure improvements. The finding was of more than minor safety significance because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, the failure to recognize conditions that could adversely affect functions described in the CLB and to perform functionality assessments could reasonably result in an unrecognized condition of a SSC failing to fulfill a safety-related or design basis function; for example, water removal from areas in the Reactor Building during high and moderate energy line break accident conditions. The finding was a licensee performance deficiency of very low safety significance (Green) because, although individual floor drains were not functional, the licensee subsequently evaluated the nonconforming conditions and concluded adequate water removal capability existed such that safety-related SSCs in the areas would remain operable or functional. The inspectors determined this finding affected the cross-cutting area of human performance and the resources aspect due to the licensees failure to ensure procedures and other resources were available and adequate to support nuclear safety (IMC 0310, H.1). Specifically, the licensees processes and procedures lacked appropriate guidance to enable licensed senior reactor operators to perform functionality assessments for degraded and/or nonconforming conditions affecting functions described in the CLB. |
