| Title | Licensee-Identified Violation |
| Description | In place of the controls required 20.1601(a) and b of 10 CFR Part 20, TS 6.12.2 requires that entryways into HRAs with dose rates exceeding 1 rem/hour at 30 cm be provided with a locked or continually guarded door or gate that prevents unauthorized entry. Contrary to this, on December 16, 2011, during the dewatering of a spent resin liner, the entryway into the Auxiliary Building Railroad Bay was controlled using remote monitoring and surveillance. During the resin transfer an individual was assigned as the access controller and a camera was placed in the area to monitor the LHRA. The access controller monitored the LHRA using the camera in Laundry/Trash Sorting area adjacent to the Railroad Bay behind a closed door. The dose rates on the top of the liner were 1500 mrem/hr at 30 cm. Although no unauthorized entry occurred during this time period, workers could have potentially entered the area from the Auxiliary Building Door. Although this event involved the failure to maintain proper control of a LHRA, this finding is of very low safety significance because there was neither evidence of unauthorized worker entry into the affected areas nor any unexpected radiation exposures to licensee personnel. |
