| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 20.1602, Control of Access to Very High Radiation Areas, requires, in part, that the licensee shall institute additional measures to ensure that an individual is not able to gain unauthorized or inadvertent access to very high radiation areas. Contrary to the above, on January 20, 2010, the licensee identified that a key to a very high radiation area (e.g., the Unit 2 sump) was located in the facilities key room. Senior radiation safety personnel onsite that were responsible for access control to very high radiation areas were unaware of the keys existence. The key was not properly controlled or inventoried in accordance with station procedures and thus available for use by unauthorized individuals. This issue was assessed by the licensee and confirmed by the inspectors to be contrary to the requirements of 10 CFR 20.1602. The issue was documented in the stations corrective action program as CAP 1214773. Corrective actions included taking immediate control of the key and initiation of a detailed review of other key controlled sensitive areas at the station. The finding was determined to be of very low-safety-significance because it was not an ALARA planning issue, there was no overexposure nor potential for overexposure, and the licensees ability to assess dose was not compromised. This issue was assessed by the licensee to be an occupational radiation safety performance indicator occurrence. The inspectors reviewed the licensees evaluation of the circumstances surrounding their control of very high radiation area keys to determine if indicator related data was adequately assessed and reported. The inspectors reviewed the details of the data reported and determined accuracy for compliance to NEI Document 99 02, Regulatory Assessment Performance Indicator Guideline, Revision 6 |
