| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.7.2.b states, in part, that each entryway to an area with dose rates greater than 1 rem/hour at 30 centimeters from the source shall be conspicuously posted as a high radiation area. Access to and activities in such area shall be controlled by means of a radiation work permit or equivalent that includes specification of radiation dose rates in the immediate work area(s). Contrary to the above, at approximately 7:00 a.m. on March 12, 2009, an individual inadvertently crossed the boundary for the locked high radiation area at the entrance to the stairway to the cavity. The individual was not signed in on a radiation work permit that allowed access to locked high radiation areas; and therefore, did not get a briefing on the dose rates in the area. The violation was identified by the radiation protection technician who immediately informed the individual to exit the area. This issue has been documented as Notification 50211054. The finding was determined to be of very low safety significance because it did not involve as low as is reasonably achievable planning and controls, did not involve an overexposure, did not have a substantial potential for overexposure, and did not result in an impaired ability to assess dose |
