Radiant is developing the first portable, zero-emissions power source that works anywhere. Its patented portable nuclear microreactor is the brainchild of former SpaceX engineers who have experience quickly bringing real products and innovations to the market. Radiant’s clean-energy solution uses safe fuels that have already been extensively tested by the Department of Energy, materials that have already been used in prior nuclear designs, and a nuclear core design based on sixty years of progressive innovation. Radiant can offer a low cost, a portable renewable power source that can be an alternative to fossil fuels for both military and commercial applications.
