| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.7.2.a.1; requires keys that provide access to areas greater than 1.0 rem/hour at 30 centimeters from the radiation source or from any surfaces penetrated by the radiation, but less than 500 rads/hour at 1 meter, shall be maintained under the administrative control of the radiation protection manager (RPM) and the shift supervisor. Contrary to the above requirement, a tagged master key that reads this key controls access to a LHRA, emergency use only was self issued by an operation staff member to access the borated water storage tank (BWST) pit, an area not posted LHRA room. By self issuing the master LHRA key, the licensee failed to maintain the LHRA key under the administrative control of the RPM and his designee. This event was entered into the licensees corrective action program (CR 09-56901). The radiation protection department immediately took control of the LHRA access key. The control room key locker was inspected and inventoried to ensure no other LHRA keys were inside. The inventory did not identify an additional problem with key control. The RP department took control of the shift supervisors LHRA keys. In addition, all LHRA keys and two containment/two auxiliary master keys and their locking mechanisms were replaced and re-cored to prevent future uncontrolled key issues. The inspectors reviewed the licensees assessment of the PI for occupational radiation safety to determine if PI related data was adequately assessed and reported. The issue is of very low safety significance because it did not involve ALARA planning or work controls, an overexposure, substantial potential for overexposure, or limit the ability to assess radiation dose. |
