Oak Ridge National Laboratory has for the first time designed, printed, and irradiated a specimen capsule—or rabbit capsule—for use in its High Flux Isotope Reactor (HFIR), the Department of Energy announced on January 15.

Ultra Safe Nuclear Corporation (USNC), a Seattle-based reactor developer, has licensed an additive manufacturing technique developed at the Department of Energy’s Oak Ridge National Laboratory to print refractory materials into structural and core components for the company’s microreactor designs.

The Transformational Challenge Reactor (TCR) program was launched in 2019 to demonstrate that highly improved, efficient systems can be created rapidly by harnessing the major advances in manufacturing, materials, and computational sciences that have emerged since the end of the first nuclear era. The Department of Energy’s Oak Ridge National Laboratory leads the TCR program, which includes contributing partners from other DOE national laboratories and the U.S. nuclear industry. The program leverages some of the nation’s leading scientists and engineers and draws from ORNL’s lengthy history, institutional knowledge, and capabilities in high--performance computing, materials science development, advanced manufacturing techniques, and nuclear science and engineering.
