| Title | Did Not Follow Radiation Protection Procedures |
| Description | The inspectors identified an NCV of T.S. 5.4.1.a, Procedures, because Constellation did not implement radiation protection procedural requirements for obtaining airborne radioactivity samples prior to workers entering the Unit 2 steam generators. Specifically, on February 25, 2009, Constellation did not conduct airborne radioactivity samples to evaluate radiological conditions prior to worker entry as required by radiation work permit (RWP) No. 2009-2408. This resulted in workers entering an area in which radiological conditions were not fully characterized. Constellation subsequently obtained air samples and entered the finding into their CAP. The finding is more than minor because it is associated with the Occupational Radiation Safety cornerstone attribute of program and process and affected the cornerstone objective of protecting worker health and safety from exposure to radiation. Specifically, Constellation did not fully characterize airborne radioactivity concentrations in the steam generators prior to worker entries. Using IMC 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, the inspectors determined that the finding was of very low safety significance (Green) because it did not involve: (1) as low as reasonably achievable (ALARA) planning and controls; (2) an overexposure; (3) a substantial potential for overexposure; or (4) an impaired ability to assess dose. This finding has a cross-cutting aspect in the area of human performance because Constellation did not effectively communicate expectations to personnel to follow RWP requirements (H.4.b) |
