Radiant CEO, mass produced portable nuclear reactors starting in 2026!
Formerly 12 years SpaceX - Electrical and Systems, Grasshopper Rocket, Boring Co., Mars
- Feast your eyes on two metric tons of West Virginia graphite that will be slowing down neutrons in our first nuclear reactor by next year! Baked at over 2500C by Amsted Graphite Materials, itโs the first reactor order of American-made, nuclear-grade, graphite in over a decade.
- .@elonmusk-No new nuclear reactor design has been licensed in over 50 years in the US. Compact nuclear enables Moon/Mars fuel production, in-space propulsion, and powers remote locations on earth. Our Govt is spending billions again without milestones. Will DOGE fix US nuclear?
- Kaleidos is a 1MW gas cooled portable microreactor Radiant will mass produce. There are nearly 10 tons of graphite in a hefty stainless steel pressure vessel. Is it hard to build these quickly? No. See for yourself in a timelapse of our full scale passive cooling demo unit!
00:00 - We @RadiantNuclear are announcing our $100m Series C today. Our plan: - Test our new reactor design at @INL - Begin mass manufacturing reactors - Deliver 1MW reactors to critical areas across the globe Reach out if you'd like to join us and build a new atom splitting machine!
- Electric power generation in the US grew exponentially from 1950-1974, became linear 1970-2007, then flattened, with almost no increase in the last 17 years. Power creates Prosperity, the United States must grow again. Chart make you smart->
- Borne of Fire, the Strength to Contain Fission. - Over 6 tons of American Forged Nuclear Reactor Pressure Vessel from @ScotForge! Coming to @RadiantNuclearโs headquarters for reactor assembly later this year.
- America invented the nuclear industry, but itโs been stuck in a rut for decades. Next year, when @radiant flips the switch on the first new design of a U.S. reactor in 50 years, itโs more than just a new innovation โ or the dawn of a new nuclear age โ it's the resumption of
- Ski resorts are on low reliability areas of the electric grid and use backup generators to avoid stranding skiers. As soon as 2029, a resilient nuclear microreactor could carry you back up the hill, on a reliable and clean microgrid keeping the mountain air 100% fresh!โท๏ธ๐
- Replying to @DWMcAliley1791They're called High Temperature Gas Reactors. Check out Ft St Vrain reactor
- Replying to @meeralSnakbarGood points. The latest new graphite reactor went fully on grid in China in 2023(en.wikipedia.org/wiki/HTR-PM), so it is quite modern, just less common than water based reactors. The neat trick here is you can make meltdown proof fuel using graphite and other layers with TRISO fuel:
- We're honored to have been selected as a member of the Nuclear Reactor Pilot Program, and look forward to making history next year when we turn on our reactor!
