| Title | Licensee-Identified Violation |
| Description | A violation of 10 CFR 50.65(b)(2)(i) was identified by the licensee during a review of systems and components utilized in the emergency operating procedures (EOP) as compared to functions scoped into the sites Maintenance Rule Program. While reviewing emergency operating procedure DEOP 3001, Secondary Containment Control the Site Maintenance Rule Coordinator (SMRC) noted that one of the entry criterion for the procedure included receiving a Reactor Building Floor Drain Sump (RBFDS) Hi-Hi level alarm. The SMRC noted that the RBFDS was scoped into the Maintenance Rule Program, but the Hi-Hi level alarm function was not. This event was entered into the licensees CAP as IR 1698084. The failure to scope into the Maintenance Rule Program non-safety related structures, systems, and components that are relied upon to mitigate accidents or transients or are used in plant emergency operating procedures was considered a performance deficiency. The finding was determined to be more than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, dated September 7, 2012, because if left uncorrected, the performance deficiency would have the potential to lead to a more significant safety concern. Specifically, if left uncorrected, no maintenance performance criteria would have been established to ensure the reliability of a function serving as an entry criterion for an EOP associated with maintaining containment integrity. The inspectors evaluated the finding using IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, Tables 2 and 3, and Appendix A, The Significance Determination Process (SDP) for Findings At Power, Exhibit 3, Barrier Integrity Screening Questions, dated June 19, 2012. The inspectors answered No to the Appendix A, Exhibit 3 barrier integrity screening questions, therefore, the finding was determined to be of very low safety significance (Green). Licensee corrective actions included adding the RBFDS alarm function into the Maintenance Rule Program and performing an extent of condition review of all EOPs for SSC not scoped into the Maintenance Rule Program. |
