Hustler Words – In a significant development for the future of clean energy and artificial intelligence infrastructure, Kairos Power, a leading nuclear startup, has announced a major collaboration with Samsung C&T. This strategic alliance will see the South Korean engineering giant assist in the construction of Kairos Power’s 50-megawatt demonstration reactor, specifically designed to power Google’s operations, with a target completion date of 2030.
The partnership involves a substantial financial commitment from Samsung C&T, totaling up to $100 million. This sum comprises a $70 million equity investment in Kairos Power, as confirmed by a company spokesperson to hustlerwords.com, complemented by the provision of valuable "in-kind" engineering services. Samsung C&T brings a wealth of experience to the table, having contributed to the development or construction of approximately a dozen nuclear facilities worldwide.
Kairos Power is at the forefront of a new wave of nuclear energy innovators, benefiting from the escalating demand for electricity, particularly from energy-intensive AI data centers. Google initially partnered with Kairos in the fall of 2024, outlining an ambitious goal for the startup to deliver nuclear reactors capable of generating roughly half a gigawatt of power by 2035.

Currently, Kairos Power is actively developing two reactors in Oak Ridge, Tennessee. The first, Hermes 1, serves as a low-power demonstrator, crucial for refining the company’s commercial reactor design. Following this is Hermes 2, slated to be Kairos’s inaugural commercial-scale reactor. The 50 megawatts generated by Hermes 2 will fulfill the initial segment of its agreement with Google.
The Nuclear Regulatory Commission granted approval for the construction of these reactors in late 2024. Kairos anticipates Hermes 2 will commence operations by 2030, aligning perfectly with the original timeline established with Google.
Hermes 2 will feature a fluoride salt-cooled high-temperature reactor design, a concept that has been explored for years but never before realized at a commercial scale. The inherent high boiling points of fluoride salts are a key advantage, facilitating low-pressure operations. This characteristic significantly mitigates the risk of high-pressure blowouts in the event of component failures, enhancing safety.
Furthermore, Kairos is leveraging a relatively novel nuclear fuel known as TRISO. This advanced fuel design involves encapsulating tiny uranium fuel seeds within multiple layers of ceramic and carbon, which are then integrated into spheres roughly the size of billiard balls. This innovative arrangement is specifically engineered to prevent meltdowns, offering an additional layer of safety.
The startup faces an accelerated, yet deemed manageable, timeline within the nuclear industry to bring its initial power plant online within approximately five years. To meet the broader terms of its extensive deal with Google, Kairos will need to expedite the development of subsequent reactors even further—a process where Samsung C&T’s extensive expertise could prove invaluable.
