The Nuclear Regulatory Commission (NRC or Commission) is amending its regulations to broaden the scope of the regulations applicable to persons who may require access to classified information, to include persons who may need access in connection with licensing and regulatory activities under the regulations that govern the disposal of high-level radioactive waste in geologic repositories, and persons who may need access in connection with other activities as the Commission may determine, such as vendors of advanced reactor designs. The Commission is also amending its regulations to broaden the scope of the regulations applicable to procedures for obtaining facility security clearances, to include persons who may need to use, process, store, reproduce, transmit, transport, or handle NRC classified information in connection with the above-identified activities. In addition, NRC is correcting the scope section of the regulations that govern access authorization for licensee personnel to include certificate holders and applicants for a certificate; clarifying the definition of "license" in the regulations that govern access authorization for licensee personnel and govern facility security clearance to include a reference to the regulations that govern combined licenses; correcting a typographical error in the definition of "security container" in its facility security regulations; and updating the references to Executive Order 12958 which has been amended.
