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.

A method for calculating the depletion and production of uranium, plutonium, transplutonium nuclides, and fission products (DPUFP) in a boiling water reactor was evaluated using measured values for JPDR-1 nuclear fuel. The results show that (a) a three-dimensional nuclear thermohydrodynamic calculation is required for an accurate estimate, (b) the void fraction of a fuel assembly has a large effect on the production of transplutonium nuclides, (c) the measured values can be applied universally by correcting the irradiation and cooling histories and the effect of the neutron spectrum, (d) more reliable DPUFPs are obtained by closely correlating the calculated value of 134Cs/137Cs with the measured values, and (e) the effective neutron cross sections of uranium and plutonium can be obtained using the measured values.
