Title | Failure to Maintain Control and Continuous Coverage of a Posted Locked High Radiation Area |
Description | The inspector identified a non-cited violation of Technical Specification 5.7.2, resulting from the licensees failure to maintain controls by not providing continuous coverage in a posted locked high radiation area with dose rates greater than 1000 mrem per hour at 30 cm during Refueling Outage 26. As corrective action, the licensee performed an apparent cause evaluation and documented the issues identified in Condition Report CR-CNS-2011-09785. The failure to maintain controls in a posted locked high radiation area is a performance deficiency. The finding was more than minor because it was associated with the program and process attribute (exposure control) of the Occupational Radiation Safety Cornerstone and affected the cornerstone objective, in that, the failure to maintain controls and not provide continuous radiation protection coverage in a posted locked high radiation area with dose rates greater than 1000 mrem per hour at 30 cm had the potential to increase personnel dose. Using NRC Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, the inspector determined the finding to be of very low safety significance because: (1) it was not associated with as low as reasonably achievable (ALARA) planning or work controls; (2) there was no overexposure; (3) there was no substantial potential for an overexposure; and (4) the ability to assess dose was not compromised. The finding has a human performance cross-cutting aspect associated with work practices component because the licensee did not ensure appropriate supervisory oversight of work activities to support nuclear safety. |
