Final answer:
The NRC does not have authority over USAF bases; therefore, they cannot perform no-notice inspections there. An assertion that they can is false.
Step-by-step explanation:
The statement about an NRC inspector being able to conduct a no-notice inspection at a USAF base at any time is false. The NRC, or Nuclear Regulatory Commission, oversees civilian nuclear facilities and does not have the authority to inspect military installations. The USAF, or United States Air Force, would fall under the purview of the Department of Defense and its internal oversight mechanisms, not the NRC. Furthermore, no-notice inspections would typically be carried out by an entity with jurisdiction over the site in question, and military bases have their own protocols for inspections.
