DOE is seeking information, comments, feedback, and recommendations from interested parties to determine what capabilities supporting research, training, and technology demonstrations are of highest interest to the nuclear energy research community. In addition to receiving feedback on the aforementioned capabilities, DOE seeks input on other high priority nuclear energy-related infrastructure needs including information on the potential benefit, location, funding model, and feasibility of establishing, maintaining, and operating such facilities. It is currently envisioned that, in general, supported facilities could become part of the Nuclear Science User Facilities, which provides access to national nuclear energy infrastructure through a competitive process or through full cost recovery mechanisms.
