| Title | Failure to Comply with Radiation Work Permit Requirements |
| Description | The inspector identified a finding of very low safety significance (Green) and associated non-cited violation of Technical Specification (TS) 5.7.1.b for the failure to comply with the requirements of the radiation work permit (RWP) during the loading of the multipurpose canister (MPC) containing spent fuel at the refuel floor. The MPC containing the spent fuel bundles was shielded by a HI-TRAC outer shell that also served as the lifting yoke of the loaded MPC. Specifically, the HI-TRAC containing the MPC was serviced by the reactor services personnel and during the preparation of non-destructive dye penetrant testing process, the trunnions part of the lifting yoke device were removed from the HI-TRAC. A worker from the reactor services group on the refuel floor removed the trunnions without the approval of radiation protection (RP) personnel. This constituted a breach of the shielding of the HI-TRAC and MPC. As a result, the worker encountered radiation levels greater than those anticipated, and received unintended dose. The licensees corrective actions included counseling of the involved workers and conducting a stand-down with the reactor services department to reinforce radiological requirements along with communication expectations. The licensee completed an apparent cause evaluation to formulate additional actions to prevent recurrence. The finding was more than minor because it is associated with the program and process attribute of the Occupational Radiation Safety Cornerstone and adversely affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation, in that, access into high radiation areas whose radiological conditions were unknown placed the worker at risk for unnecessary radiation exposure. The finding was determined to be of very low safety significance because it was not an as-low-as-is-reasonably-achievable (ALARA) planning issue, there was no overexposure or substantial potential for an overexposure, and the licensees ability to assess worker dose was not compromised. The finding involved a cross-cutting aspect in the area of Human Performance, Decision-Making, in that, the worker failed to comply with the RWP requirements for RP hold-points for breaching of a system. Specifically, the decision to remove the trunnions was made without the approval by the RP department and validation that the removal of its parts would not have caused unintended consequences, such as radiation levels greater than anticipated. |
