| Title | Failure to Adequately Brief Workers on Radiological Conditions Prior to Entry into High Radiation Areas |
| Description | The inspectors reviewed a self-revealing, non-cited violation of Technical Specification 5.7.1 resulting from the licensees failure to control high radiation areas with radiation levels of 100 millirem per hour or greater on three separate occasions. In each instance, the licensee failed to adequately inform the worker of current radiological dose rates prior to entry and the worker entered a posted high radiation area without proper knowledge of the radiological conditions (dose rates). Consequently, the workers received unanticipated high dose rate alarms on their electronic alarming dosimeters at 563 millirem per hour, 274 millirem per hour, and at 750 millirem per hour, respectively. As immediate corrective actions, the licensee performed follow-up surveys, coached the involved individuals, and reviewed the radiologically controlled area entry card requirements. The licensee entered the three issues into the corrective action program as Condition Reports CR-2013-004154, CR-2014-003464, and CR-2014-003997
The failure to provide workers with proper knowledge of high radiation area radiologica conditions prior to entry is a performance deficiency. The performance deficiency is mor than minor because it impacted the program and process attribute (exposure control) of the Occupational Radiation Safety Cornerstone and adversely affected the cornerston objective of ensuring adequate protection of worker health and safety from exposure t radiation. Specifically, worker entry into high radiation areas without knowledge of the radiological conditions placed them at increased risk for unnecessary radiation exposure. Using Inspection Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance (Green) because: (1) it was not an as low as is reasonably achievable finding, (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 finding has a human performance cross-cutting aspect associated with teamwork because the workers failed to demonstrate and execute a strong sense of communication and collaboration in connection with the operational activities involved in the finding to ensure nuclear safety was maintained [H.4]. |
