Title
10 CFR 20.1801 states that the licensee shall secure from unauthorized removal or access licensed materials that are stored in controlled or unrestricted areas. Contrary to the above, on February 10, 2009, an access door to the radioactive material building (
RMB), a building where radioactive materials are stored, was found unsecured. This incident was identified by and documented in the licensees corrective action program as
AR 00846010. Immediate corrective actions included securing the access door. This issue represents a performance deficiency as defined in
IMC 0612 in that the issue is the result of not meeting a requirement where the cause was reasonably within the licensees ability to foresee and correct, and should have been prevented. This finding is more than minor because it is associated with the cornerstone attribute of program and processes for radioactive material control and the cornerstone objective for ensuring the adequate protection of the public health and safety from exposure to radioactive materials released into the public domain as a result of routine civilian nuclear reactor operation. The inspector then screened the finding for significance in accordance with
IMC 0609 Appendix D Public Radiation Safety SDP. The finding was of very low safety significance because although it did involve radioactive material control, the finding did not involve the transportation of radioactive material, and public exposure was less than 0.005
