| Title | Failure to Maintain Radiation Exposure ALARA During Refueling Outage 2R22 Activities |
| Description | A self-revealing finding (FIN) of very low safety significance (Green) was identified due to the accrual of excessive unintended occupational collective radiation exposure during Millstone refueling outage 2R22. This resulted from performance deficiencies in planning and work control while performing scaffolding work, valve maintenance, and a valve replacement during the Unit 2 refueling outage. No violation of NRC requirements was identified. The unintended collective radiation exposures were due to work planning and work control deficiencies that were reasonably within Dominions ability to control and prevent. The finding was more than minor because it was associated with the program and process attribute of the Occupational Radiation Safety cornerstone and adversely affected the cornerstone objective to ensure the adequate protection of the worker from radiation exposure. The performance deficiency is similar to examples in Appendix E of IMC 0612; in that the actual collective dose exceeded 5 person-rem and exceeded the planned, intended dose by more than 50 percent. The finding has a cross-cutting aspect in the area of Human Performance, Work Management, in that the Millstone organization did not implement a process of planning, controlling, and executing work activities such that station-established radiation exposure goals could be met. |
