| Title | Failure to Comply with Technical Specification and RWP Requirements during Work in a Locked High Radiation Area |
| Description | A self-revealed finding of very low safety significance and an associated non-cited violation (NCV) of Technical Specification 5.7.1.b was identified for the failure to comply with the requirements of the radiation work permit during ultrasonic testing preparations in the condenser hot side, an area posted as a locked high radiation area, on January 2, 2009. Specifically, a mechanical maintenance worker was directed by the outage control center staff to leave his assigned work area and to investigate a leak near the D moisture separator. The worker was briefed on the high radiation area conditions at the ultrasonic testing preparation area; however, the individual was not briefed on the radiological conditions along his path to the D moisture separator. As a result, the worker encountered radiation levels greater than those anticipated and received a dose rate alarm on his electronic dosimeter. The licensees corrective actions included counseling of the involved workers and conducting a stand-down with the operations department to reinforce radiological requirements and communication expectations. A radiation protection liaison was also assigned to the outage control center for the remainder of the down-power to ensure that work assignments were coordinated with the appropriate supervisor, rather than interfacing directly with the worker. The licensee had completed an apparent cause evaluation to formulate additional actions to prevent recurrence. The finding was more than minor because it impacted the program and process attribute of the Occupational Radiation Safety Cornerstone and 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 related to work practices; in that, radiation work permit compliance for access into D moisture separator areas was not effectively communicated to the worker, and the worker failed to follow the radiation work permit. |
