| Title | Unauthorized Non-Routine Maintenance on a Sealed Source Device |
| Description | The inspectors identified a non-cited violation of Callaway Plants License No. NPF-25, Condition 2.B.(3), for the licensee performing non-routine maintenance on a J.L. Shepherd calibrator without license authorization. The licensee documented this issue in their corrective action program as Corrective Action Request 201505175. Their immediate corrective action was to secure the calibration source and review their procedural requirements. Performing non-routine maintenance on a J.L. Shepherd calibrator without a license authorization is a performance deficiency. This finding is more than minor because the performance deficiency adversely affects the Occupational Radiation Safety Cornerstone, in that, if the licensee performs non-routine maintenance on radiologically risk significant sources without being specifically authorized or trained on how to perform the non-routine maintenance, an uncontrolled high radiation area could result. Using Inspection Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008, the inspectors determined the violation was of very low safety significance (Green) because (1) it was not an as low as 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 had a conservative bias cross-cutting aspect in the area of human performance, because individuals did not use decision making practices that emphasized prudent choices over those that were simply allowable, or ensure a proposed action was safe in order to proceed, rather than unsafe in order to stop. Specifically, licensee staff assumed that they could perform any type of maintenance on the calibrator without verifying that their license authorized those activities [H.14]. |
