| Title | Failure to Maintain Dose ALARA due to Inadequate Job Planning |
| Description | The inspector reviewed a self-revealing finding, with two examples, for failure to maintain doses as low as is reasonably achievable (ALARA) due to inadequate job planning. In the first example, the licensee estimated that Radiation Work Permit 30002636, R20 DW CRA-M/FN Maintenance and Repairs LHR, would accrue 10.549 person-rem (as revised), but actually accrued 22.657 person-rem. In the second example, the licensee originally estimated that ALARA Task 11824040102 attached to Radiation Work Permit 30002684, R20 RF Wetwork Invessel, SFP, and Equipment Pool HR, would accrue 3.557 person-rem, but the actual dose accrued was 11.683 person-rem. The primary reason for exceeding the estimated dose was identified as inadequate job planning. This was documented in the licensees corrective action program as Action Requests 00238694 and 00239554, respectively. This finding is greater than minor because it is associated with the Occupational Radiation Safety Cornerstone, exposure control attribute, and affected the cornerstone objective in that it caused increased collective radiation dose for occupational workers. The inspector determined this finding to be of very low safety significance because although the finding involved ALARA planning and work controls, the licensees latest three-year rolling average collective dose was less than 240 person-rem. This finding had a cross-cutting aspect in the human performance area, associated with the work control component, because the licensee failed to incorporate job site conditions, including plant structures, systems, and components, human-system interface, radiological safety, and planned contingencies and compensatory actions to be consistent with nuclear safety. |
