The Department of Defense, through the North American Aerospace Defense Command (NORAD) and United States Northern Command (USNORTHCOM), is seeking contributions from industry, laboratory, and academic partners for a small fission reactor experiment aimed at enhancing technology readiness in compact reactor designs for both space and terrestrial applications. The primary objective of this initiative is to validate the neutronic behavior of hydride moderated compact nuclear reactors, addressing the current lack of a validated nuclear benchmark that limits commercial adoption. Interested organizations are invited to submit their capabilities and relevant information by September 16, 2024, to potentially collaborate on this project, which does not guarantee contract awards or remuneration.
