| Title | Failure to Appropriately Control Access to a Locked High Radiation Area |
| Description | The inspectors identified a noncited violation of Technical Specification 5.8.3 for the failure of radiation protection personnel to appropriately barricade and conspicuously post an area that was accessible to personnel that could have resulted in radiation doses greater than 1.0 rem in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. Specifically, from February 2004 through March 17, 2010, the radiation personnel failed to appropriately barricade and conspicuously post the access ladder to the upper refueling cavity when it was being used as the means to control access to an individual high radiation area in the lower cavity where the maximum measured radiation dose rate was 2.8 rem per hour. The inspectors determined that the ladder was not appropriately barricaded and conspicuously posted, and as such the controls the licensee had in place were easily circumvented. On March 17, 2010, radiation protection personnel appropriately barricaded and conspicuously posted the access ladder to the upper refueling cavity. This issue was entered into the licensees corrective action program as Nuclear Notifications NNs 200793188 and 200837345. The finding is greater than minor because it is associated with the program and process attribute of the Radiation Safety Cornerstone and directly affected the associated cornerstone objective of ensuring the adequate protection of the worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. Using Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, this finding is determined to have very low safety significance because it did not involve: (1) an ALARA planning or work control issue, (2) an overexposure, (3) a substantial potential for overexposure, or (4) an impaired ability to assess dose. The inspectors determined that since the licensee had not recently re-evaluated the locked high radiation area controls associated with this ladder; this finding did not represent current plant performance, and therefore, did not have a crosscutting aspect associated with it. |
