The National Reactor Innovation Center is accepting applications from developers ready to take a fueled microreactor to criticality inside the former Experimental Breeder Reactor-II containment building at Idaho National Laboratory, now repurposed as DOME—a microreactor test bed. According to a Department of Energy announcement, DOME will be ready to receive the first experimental reactor in the fall of 2026, with testing likely to begin in 2027.

Radiant Industries has announced a $100 million Series C funding round to be used primarily to complete its Kaleidos Development Unit (KDU) microreactor for testing in Idaho National Laboratory's Demonstration of Microreactor Experiments (DOME) facility within two years.
