The inspectors identified a performance deficiency involving a
NCV of
Technical Specifications 5.4.1, for the licensees failure to provide procedural controls for the unique identification of
Regulatory Guide 1.97 post-accident instrumentation to aid the control room operator. Specifically, the licensee failed to adequately control the labeling on both units control panels and the simulator, resulting in several improperly marked post-accident indicators. The licensee has entered the issue into their corrective action program and labeled the appropriate post-accident instruments. The finding was greater than minor because, if left uncorrected, it could become a more significant safety concern. Inaccurately labeled control room indicators of post-accident instrumentation could
lead to confusion and hamper operator response if conflicting indications resulted due to accident conditions. The finding was determined to be of very low safety significance based on a
SDP Phase 1 screening in accordance with
IMC 0609.04, Initial Screening and Characterization of Findings. The inspectors did not identify a cross-cutting aspect to this finding
