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 diffusion coefficients of D2 in Nb—1 wt% Zr were determined in the range from 923 to 1148 K. A hollow-cylinder model, used as the frame of reference, adequately described the transport of D2 through the alloy containing oxygen impurities. The diffusion coefficient is temperature dependent and is best described byD (m2/s) =8.5 ± 7 × 10−8 exp (−48.2 ± 6.7 × 103/RT) .
