Duke Energy Response: Duke Energy operates 3 nuclear power stations (Oconee, McGuire and Catawba) in North Carolina and South Carolina, both of which are NRC agreement states. Duke’s normal TLDs change-out frequency semiannually (6 months). Duke has an in-house radiography team and we possess our own state radioactive material licenses for radiography work. Work under these state licenses requires a quarterly TLD change-out frequency to comply with NRC 10CFR34 and state regulations.
Duke also owns several state radioactive material licenses and x-ray registrations. The TLD change-out period for work under these licenses is also semiannually. Only work under the radiography license requires a quarterly TLD change-out frequency. If you have further questions, please contact: Changfuh D.

Fermi 2 and other NRC Licensed facilities are moving towards six-month dosimetry monitoring periods. When I stated that to an inspector from The State of Michigan he said that would be a noncompliance issue. He said Michigan Rules state that monitoring periods must not be greater then quarterly. Has anyone else run into this problem? Thomas M. Lashley, RSO Principal Radiological Engineer DTE Energy, Fermi 2 734-586-1697
