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.

The absolute cumulative fission yield of 140Ba and the relative yields of 131I, 132Te, and 141Ce were measured for 232Th irradiated in a 252Cf fission spectrum of neutrons. The irradiation was performed using two 232Th foils in contact with a nominal 1-mg 252Cf source in a large evacuated area for 41 days. The absolute yield of 140Ba was deduced from an absolute measurement of its daughter product 140La using a calibrated NaI(Tl) detector. The activities of 131I, 132Te, and 141 Ce were measured relative to the 1596-ke V gamma ray of 140La using a 43-cm3 Ge(Li) detector. The fission rate for the yield measurement and the integral fission cross section were measured using mica solid-state track recorders.
