Company Description
Radiant Industries is a clean energy company developing portable nuclear microreactors as an alternative to fossil fuels. Founded in 2019 by former SpaceX engineers, including current CEO Doug Bernauer, the El Segundo-based startup is focused on its first product, Kaleidos. This 1 MW failsafe microreactor is designed to fit within a shipping container for rapid deployment to provide power for military, commercial, and remote applications. The company's approach combines established nuclear technologies with modern engineering to create a portable, zero-emissions power source.
Looking ahead, Radiant plans to conduct a fueled prototype test of its Kaleidos reactor in 2026 at the National Reactor Innovation Center's DOME facility, with initial customer deployments scheduled for 2028. The company has secured several significant agreements, including a deal with digital infrastructure company Equinix for the purchase of 20 microreactors. Radiant also has an agreement with the Defense Innovation Unit and the United States Air Force to deliver a reactor to a U.S. military base by 2028. Additionally, the company became the first U.S. advanced reactor developer to sign a commercial contract for HALEU enrichment services and the first to sign a contract with the U.S. Department of Energy to receive HALEU fuel for testing.
