| Title | Licensee-Identified Violation |
| Description | Technical Specification 6.12.2 establishes controls for areas accessible to personnel with radiation levels such that a major portion of the whole body could receive in one hour a dose greater than 1000 mrems but less than 500 mrads and requires such areas be barricaded and conspicuously posted. In addition, such area shall be provided with locked doors to prevent unauthorized entry. Where no enclosure exists for purposes of locking and no enclosure can reasonably be constructed around the individual area, then that area shall be roped off, conspicuously posted and a flashing light shall be activated as a warning device. Contrary to this requirement, on April 1, 2012, licensee representatives discovered an area on a container in the fuel handling building with a localized dose rate of 1400 mrems/hour at 30 centimeters from the source which had not been barricaded, conspicuously posted, and locked or surrounded by a rope with flashing lights. Licensee representatives had an opportunity to identify the dose rates 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> earlier, when another survey was performed in the same area. The area was uncontrolled until the second survey was performed. The inspectors determined the violation had very low safety significance because: (1) it was not an as low as is reasonably achievable (ALARA) finding, (2) there was no overexposure, (3) there was no substantial potential for an overexposure because the inspectors concluded there was no way to construct a scenario in which a minor alteration of circumstances would have resulted in a violation of the Part 20 limits, and (4) the ability to assess dose was not compromised. After the violation was identified, licensee representatives implemented the correct technical specification controls and documented issue in the corrective action program as CR-WF3-2012-01594. Additional information was documented in CR-WF3-2012-03192, on July 2, 2012. |
