| Title | Failure to Provide Positive Exposure Control Within A Locked High Radiation Area |
| Description | The inspectors identified a non-cited violation of Technical Specification 5.7.2 because a radiation protection technician did not provide positive exposure control to workers entering an area with dose rates greater than 1,000 millirem/hour. Radiation protection representatives removed the workers radiological controlled area access privileges, counseled the workers, conducted a stand-down meeting, and performed an apparent cause evaluation. The failure to provide positive control to workers entering an area with dose rates greater than 1,000 millirem/hour is a performance deficiency. The significance of the performance deficiency was more than minor because it was associated with an Occupational Radiation Safety cornerstone attribute (exposure control) and adversely affected the associated cornerstone objective because it allowed workers to be exposed to higher-than-planned radiation dose rates. The violation had very low safety significance because: (1) it was not an as low as is reasonably achievable finding because a collective dose threshold was not challenged, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. This violation has a cross-cutting aspect in the human performance area, associated with avoiding complacency, because the radiation protection technician did not recognize and plan for the possibility of mistakes by the operators in identifying the correct valve to tag, and the inherent risk of the operators entering an unsurveyed area [H.12]. |
