The inspectors reviewed a self-revealing, … The inspectors reviewed a self-revealing, non-cited violation of Technical Specification 5.4.1, associated with an operator who entered a high radiation/high-noise area contrary to an ALARA pre-job briefing and without highnoise dosimetry as required by Special Work Permit 2012-051. The licensee entered this issue into their corrective action program as Condition Report CR-CNS-2012-10636. The failure to follow special radiation work permit requirements when entering a high radiation/high noise area was a performance deficiency. This performance deficiency was more than minor and therefore, a finding, because it was associated with the program and process attribute of the Occupational Radiation Safety cornerstone and affected the associated cornerstone objective to ensure the adequate protection of the workers health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. Specifically, this finding resulted in an operator received an unintended and unexpected radiation dose. Using Inspection Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, the inspectors determined that finding was of very low safety significance (Green) because: (1) it was not associated with as low as is reasonably achievable (ALARA) planning; (2) it did not involve an overexposure; (3) there was no substantial potential for an overexposure; and (4) the licensees ability to assess dose was not compromised. The operator incorrectly assumed entry into the overheads in high radiation areas was allowed. Therefore, finding has a cross-cutting aspect in the area of human performance associated with the decision-making component because the licensee failed to use conservative assumptions in decision-making and ensure that the proposed action is safe in order to proceed, rather than unsafe in order to disapprove the action. unsafe in order to disapprove the action. +
