| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 1801, Security of Stored Material, requires that the licensee shall secure from unauthorized removal or access licensed materials that are stored in controlled or unrestricted areas. Title 10 CFR 20.2201, Reports of Theft or Loss of Licensed Material, Section (a)(ii) requires, in part, that within 30 days after the occurrence of any lost, stolen, or missing licensed material becomes known to the licensee, all licensed material in a quantity greater than ten times the quantity specified in Appendix C to 10 CFR Part 20 that is still missing at this time. Contrary to the above, when the radioactive source inventory was performed in November 2009, it was identified that a source of reportable quantities was missing. Specifically, a 0.07 iCi U-234 source installed in a radiation monitor detector could not be located. Although this condition was known to the licensee staff, no corrective action program document was immediately initiated, and the issue was not reported to the NRC until January 16, 2009, which was beyond the 30-day reporting window. This was tracked by the NRC as Nuclear Material Events Database (NMED) #100030. The issue was documented in the licensees corrective action program as CAP 01214773. Corrective actions included performance management of the individuals involved in accordance with station protocol and station procedures for inventory and control of radioactive sources were revised to provide more explicit direction on source control and reportability. Additionally, an investigation was initiated by the licensee that concluded that the most probable disposition of the source was as low level waste at a licensed radioactive waste facility. The loss of control of radioactive material (radioactive sources) is a performance deficiency as defined in NRC IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening. The inspectors determined that the finding was more than minor because it impacted the program and process attribute of the public radiation safety cornerstone and adversely affected the cornerstone objective of ensuring adequate protection of public health and safety from exposure to radiation, in that, radioactive material in quantities of greater than ten times 10 CFR Part 20, Appendix C were potentially released into the public domain. The finding was determined to be of very low safety-significance because: (1) it involved a radioactive material control issue that was contrary to NRC requirements (10 CFR Part 1801) and the licensee\'s procedures; and (2) the dose impact to a member of the public was less than 5 millirem |
