Today, we unveiled our completed Critical Test Reactor facility. We will be turning this reactor on (a “zero power criticality”) well before July 4th! This is a commercial-scale system with enough fuel to produce 10 MW of electricity, and will someday soon power a co-located data center from one of our partners. Here’s what people saw today at our ribbon cutting: ✅ Reactor vessel ✅ Graphite as moderator ✅ Instrumentation and control ✅ Concrete shielding ✅ Building with crane ✅ Control room All designed and built by Aalo. And the nuclear fuel will be arriving any day now. One last step remains: the final DOE approval to turn the reactor on, which we expect to receive soon. DOE has been an incredible partner in this 2.5 year journey, working hard to support a number of companies pushing to advance US nuclear energy. Follow us to be the first to know when we turn this reactor on!
