The inspectors identified a non-cited viol … The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, associated with the licensees failure to follow station procedure PPM 1.3.57, Barrier Impairments , Revision 29. On March 29, 2013, the inspectors walked down the main control room and noted that damper WEA-AD-51 had failed to move from an intermediate to its closed position. A review by the inspectors revealed that the licensee failed to enter the appropriate technical specification action statements as required by PPM 1.3.57 for the failed damper. Based on questions posed by the inspectors, the licensee took action to close and gag shut damper WEA-AD-51 on March 29, 2013. The licensee entered this issue into their corrective action program as Action Request AR 288508. The performance deficiency was more than minor because it affected the configuration control attribute of the Barrier Integrity Cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect the public from radionuclide releases caused by accidents or events. The inspectors performed an initial screening of the finding in accordance with Inspection Manual Chapter 0609.04, Phase 1 - Initial Screening and Characterization of Findings, and determined the finding to be of very low safety significance because it only represented a degradation of the radiological barrier function provided for the control room. The inspectors determined that this finding had a cross-cutting aspect in the area of human performance associated with the resources component because the licensee failed to maintain complete, accurate and up-to-date design documentation. Specifically, Technical Memorandum TM-2082, Control Room Envelope Boundary Control, Revision 5, contained out of date design information which caused station operators to not consider procedure PPM 1.3.57 applicable to damper WEA-AD-51.PPM 1.3.57 applicable to damper WEA-AD-51. +
