The NRC is adapting its regulatory framework to align with advanced reactor technologies by refining what qualifies as "construction" and ensuring right sized, safety focused oversight that enables efficient, safe, and timely deployment. This session will highlight the NRC's efforts to enable more efficient construction, implementation of tailored oversight activities of advanced reactors, and insights from construction activities. It will focus on changes to the application of the definition of "construction," the Advanced Reactor Construction Oversight Program development progress, developer perspectives and experience with construction, and insights from developers on the factory fabrication process. It will provide the audience with an understanding of how recent regulatory initiatives expand opportunities for preconstruction activities, improve oversight efficiency, and support the safe deployment of next generation nuclear technologies.
