Nuclear Microreactors Advance as US Picks Two Companies for Fueled Testing (postregister.com) 188
This week America's Energy Department selected two companies to perform the first nuclear microreactor tests in a new facility in Idaho, saying the tests "will fast-track the deployment of American microreactor technologies... The first fueled reactor experiment will start as early as spring 2026."
The new facility is named DOME (an acronym for Demonstration of Microreactor Experiments), and it leverages existing "to safely house and test fueled reactor experiments, capable of producing up to 20 megawatts of thermal energy," according to a local newspaper. [T]wo companies were competitively selected in 2023 and are currently working through a multi-phase Energy Department authorization process to support the design, fabrication, construction, and testing of each fueled reactor experiment. Both are expected to meet certain milestones throughout the process to maintain their allotted time in DOME and to ensure efficient use of the test bed, according to the release... The department estimates each DOME reactor experiment will operate up to six months, with the DOME test bed currently under construction and on track to receive its first experiment in early 2026... The next call for applications is anticipated to be in 2026.
The site Interesting Engineering calls the lab "a high-stakes proving ground to accelerate the commercialization of advanced microreactors..." Based in Etna, Pennsylvania, Westinghouse will test its eVinci Nuclear Test Reactor, a compact, transportable microreactor that uses advanced heat pipe technology for passive cooling. Designed to deliver 5 megawatts of electricity on sites as small as two acres, eVinci could support applications ranging from remote communities to mining operations and data centers. Meanwhile, Radiant (El Segundo, California) will test its Kaleidos Development Unit, a 1.2 megawatt electric high-temperature gas reactor aimed at replacing diesel generators. Designed to run for five years, Kaleidos is fueled by TRISO fuel particles that could offer reliable backup power for hospitals, military bases, and other critical infrastructure.
Radiant's CEO said "In short order, we will fuel, go critical, and operate, leading to the mass production of portable reactors which will jumpstart American nuclear energy dominance."

The only reason nuclear reactors are large is that their relative cost gows down strongly with size.
No, the reason reactors are so expensive in the west is every one is effectively a custom built one-off. There are no economies of scale because we build so few, even though they have standardized designs. China is fixing this problem by creating a permanent supply chain for reactors. They currently have enough heavy forge capacity for 10 pressure vessels and associated components per year, and plans (which they will most certainly meet) for 20 per year by 2030.

That is not what I said and you know it. Why are all you nuclear fanbois soft in the head? Oh, well, that is really redundant at this time.

Mass production is the key to cheaper nuclear, not size.
