NSUF 24-5022: Advanced hydride moderator irradiations for microreactor and space nuclear reactor deployment

With the recent signing of Space Policy Directive-6, a US policy goal for micro nuclear reactor and space reactor systems has been designing these systems to utilize low-enriched uranium (<20% U-235) nuclear fuel (2). However, the use of LEU, as opposed to highly enriched uranium (HEU) is accompanied by an increase in fuel mass to achieve criticality (3). One way in which the overall mass of fuel could be reduced is using moderators, which efficiently thermalize neutrons.
