| Title | Failure to Brief Worker Entry to High Radiation Area Resulting in the Unplanned Dose Rate Alarm |
| Description | Green . A finding of very -low safety significance and an associated NCV of Technical Specification 5.7.1.b was self -revealed for the failure to a make radiation worker aware of the radiation dose rate before entering a high radiation area. The failure to brief the worker resulted in an unplanned electronic dosimeter dose rate alarm. The worker immediately exited the area and reported the event to the radiation protection staff. The license e entered the event into their CAP as AR 2016 13827. The inspectors determined that the performance deficiency was more than minor i n accordance with IMC 0612, Appendix B, because the finding impacted 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. Specifically, worker entry into a high radiation area without an adequate briefing could lead to unintended dose. The inspectors also identified an example in IMC 0612, Appendix E, which is similar to the performance issue. Therefore, t he finding was determined to be of very -low safety significance in accordance with I MC 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008. The violation was of very- low safety significance (Green) because: (1) it did not involve as -low -as-reasonably -achievable planning or work controls, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. The inspectors concluded that the cause of the finding involved a cross -cutting 4 component in the human performance area, H.4, in the area of teamwork and communication and coordination across organizational boundaries, specifically between radiation protection staff and the individual . This resulted i n the worker proceeding into areas that they were not briefed to enter which contained unknown dose rates . |
