| Title | Failure to Validate Compensatory Measures During Maintenance |
| Description | The inspectors identified a non-cited violation of Technical Specification 3.7.3, Control Room Emergency Filtration (CREF) System, for the licensees failure to provide adequate compensatory measures during maintenance on the control room emergency filtration system. Specifically, the licensee failed to validate that the compensatory measures used in Procedure PPM 1.3.57, Barrier Impairment, Revision 26, were adequate to limit dose to operators to within FSAR limits during maintenance on the control room emergency filtration system. The licensee issued a stop work order pending resolution of appropriate compensatory measures. The inspectors identified this issue during follow-up inspections of Action Request 256748 that documented transferring of dedicated individual duties during maintenance to unqualified individuals. This issue was entered into the licensees corrective action program as Action Request 256960. The failure to provided adequate compensatory measures during maintenance on the control room emergency filtration system was a performance deficiency. This finding was more than minor because it affected the procedure quality attribute of the Barrier Integrity Cornerstone objective of providing reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents. The inspectors used Inspection Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, and determined the finding was of very low safety significance (Green) since it only represented a degradation of the radiological barrier function provided for the control room. The inspectors determined that a cross-cutting issue was not applicable since the procedure that introduced the mitigating measures was first introduced in 2008 without verification that the mitigating measures were adequate and, therefore, not reflective of current plant performance |
