Overview
Kairos Power, Inc. is an American private company that develops advanced nuclear reactor technology. The firm’s primary focus is on a fluoride‑salt‑cooled high‑temperature reactor (FHR) design, which utilizes a liquid fluoride salt as coolant and solid fuel assemblies. The company’s stated objective is to provide low‑cost, carbon‑free electricity through modular, scalable nuclear power plants.
History
Kairos Power was founded in the mid‑2010s in the United States. Since its inception, the company has pursued research and development of its FHR concept, targeting a prototype that could demonstrate commercial‑scale performance and regulatory compliance.
Technology
The reactor design promoted by Kairos Power features:
- Coolant: A low‑pressure liquid fluoride salt that enables high operating temperatures while maintaining favorable safety characteristics.
- Fuel: Solid uranium‑based fuel plates arranged in a geometry that allows for efficient heat transfer to the coolant.
- Thermal Efficiency: High outlet temperatures (approximately 700 °C) allow for a thermal efficiency substantially greater than that of conventional light‑water reactors.
- Safety: The fluoride‑salt coolant is chemically stable and has a high boiling point, reducing the risk of high‑pressure loss‑of‑coolant accidents.
The company’s conceptual system, often referred to as the “KP‑2” reactor, is projected to generate several hundred megawatts of electrical output, though specific performance parameters have not been publicly certified by regulatory bodies.
Funding and Partnerships
Kairos Power has attracted venture‑capital and strategic investment from entities focused on clean‑energy technologies, including Breakthrough Energy Ventures and Khosla Ventures. The firm has also engaged with academic and national‑laboratory partners to advance materials research and licensing strategies.
Regulatory and Development Status
As of the latest publicly available information (2023), Kairos Power was in the pre‑construction phase, pursuing design certification and licensing through the United States Nuclear Regulatory Commission (NRC). The company has indicated plans to construct a demonstration plant, but construction timelines and final approval status remain pending.
