| Title | Failure to Conspicuously Post a Radiation Area |
| Description | The team identified a noncited violation of 10 CFR 20.1902(a) because the licensee failed to conspicuously post a radiation area in the radwaste storage yard with a sign or signs bearing the radiation symbol and the words Caution, Radiation Area. The licensee had posted radiation area signs only at the entrances to the outdoor radwaste storage yard, instead of a discrete radiation area within the yard. The outdoor radwaste storage yard is a large area that, with the exception of this one area, had radiation levels measuring less than 2 millirem per hour. However, the general area dose rate in the unposted discrete radiation area was as high as 10 millirems per hour. As corrective action, the licensee posted the discrete areas. Additional corrective action is still being evaluated under Condition Report 08-0887. The finding was greater than minor because it was associated with one of the cornerstone attributes (exposure control and monitoring) and the finding affected the Occupational Radiation Safety cornerstone objective, in that, workers could receive unexpected radiation dose. Using the Occupational Radiation Safety Significance Determination Process, the team determined that the finding was of very low safety significance because it did not involve: (1) ALARA planning and controls, (2) an overexposure, (3) a substantial potential for overexposure, or (4) an impaired ability to assess dose. Also, this finding had a cross-cutting aspect in the area of human performance related to the component of decision making because management did not adopt conservative assumptions in implementing regulatory requirements to decrease the likelihood of radiation workers receiving unintended dose (H1.b) |
