Launching into tomorrow: NRIC guides new era of research and deployment
In June 2025, the Department of Energy announced the Reactor Pilot Program, an authorization pathway that allowed reactor developers to partner with the DOE to get first-of-a-kind (FOAK) reactors built and tested. Soon after, the DOE rolled out a complementary Fuel Line Pilot Program, which aimed to fast-track fuel projects. In all, 20 projects were accepted into the new programs.

Some storage and transportation arrays become more reactive when the fissile material density is reduced. We have calculated this effect for arrays of shipping containers and for arrays of 235U spheres. The reactivity enhancement is due mainly to increased utilization of thermal neutrons and reduction in neutron leakage resulting from the increased size of low-density units.
