Westinghouse and Radiant Industries have secured a $5 million Department of Energy (DOE) award to advance their microreactor designs for testing at the Demonstration of Microreactor Experiments (DOME) testbed at Idaho National Laboratory (INL)— the world’s first facility, specifically designed to support fueled reactor experiments for advanced nuclear technologies.
The two companies, along with Ultra Safe Nuclear Corp. (USNC), received a combined $3.9 million in October 2023 as part of the DOE’s initial funding round to advance their microreactor designs through a front-end engineering and experiment design (FEEED) process. The second round of funding, a combined $5 million, announced on Nov. 18, builds on that progress, allowing Westinghouse and Radiant to enter the detailed engineering and experiment planning (DEEP) phase, which includes completing a Preliminary Documented Safety Analysis (PDSA)—a critical step before reactor fabrication and testing, the DOE said.
