Radiant(@RadiantNuclear):Kaleidos is making history. The @INL DOME hasn't hosted a new reactor design test since EBR-II shut down in the 1990s. That's roughly 30 years without this kind of hands-on, full-power testing & validation of new nuclear technology on U.S. soil. That changes today. Radiant earned this spot through a competitive DOE down-select, evaluated on design maturity and execution readiness against the rest of the field. We were assessed as the most mature company in the space, and we now hold exclusive use of DOME for full-scale, full temperature commercial testing. Proud doesn't quite cover it. @NRICnuclear Let's get to work!
