Here are the nuclear fission startups backed by Big Tech

Artificial intelligence has sent a demand for electricity in the United States after zero growth for years. This sent great technological companies to provide production capacity for data centers.

This is designed for many Turning into a nuclear fit. The source of power is experiencing a revival in several years in the end of plant parcels in the last few years. (Fission, used in all current nuclear power plants, is different from the Fusion, an experimental approach from pomposis When investors are involvedshould produce more electricity than they still consume.)

For technical companies, part of the disclosure of a physting, 24/7 is a stable, projected power source, and the potential to manage calculation loads when they require data centers.

However, another part of the appeal lies in new reactors in the new reactors who promise to repel the shortcomings of existing nuclear power plants. Former power plants are built around mass reactors, which can produce more than 1, new small module reactor (SMMR) designs are looking for many modules placed with each other to meet a number of needs.

SMRS rely on mass production to lower costs, but no one has been still kept yet Amazon, Google, Metaand Microsoft away from the table. They have signed contracts to either get power from nuclear start or to invest directly or to both.

Here are nuclear fragment startups supported by Big Tech.

Cairo power

Cairo power When the search giant has received a vote from Google promised to buy Until 2035, 500 megawatts of electricity, the first reactor aims to come online until 2030.

The company’s small modular reactors rely on melted fluoride salt for cooling and carries a steam turbine. The high hot spot of the salt, the coolant does not need to be kept in high blood pressure, which must increase operating security. Reactors have fuel pebbles covered in carbon and ceramic shells, which must be strong enough to endure a melt.

Alameda Based Started One $ 629 million $ 303 million award from the US government, including the energy department. In November 2024 Kairos received approval To build a US nuclear regulatory commission on two reactors in Tennessee. In 35 megawatts, test units will be smaller than the latest trading reactors of Kairos, which will produce 75 megawatts.

Ok hey

Ok hey The data center is another SMR company targeting – there is no surprise that Openai CEO SAM Altman was supported by Altman He received the nuclear beginning to the public In July 2023, a special purpose, by a combination of the special purpose of the Alt. Altman, Oklo President Oklo Chairman Oklo President Oklo, the Energy Supply Agreement has started talks with Oklo. DCVC, Draper Associates and Peter Thiel’s Mithril capital management is among the previous investors of the beginning.

Chilled Oklo Reactor with liquid metal is based on the existing energy design department, which is available to reduce the amount of nuclear waste that results in regular operations. Again, Oklo’s way was nothing smooth. Company First License Application Rejected in January 2022. Oklo, in 2025, said the application was re-sent. But this did not stop the company a bargain To provide the data center operator with 12 Gigavatt until 2044.

Salfins

Like Kairos, SalfinsWants to build chilled SMRs with both the previously known as Seaaborg. However, unlike Kairos and others, a power barge is caused by two to eight to eight to eight in one ship to create. Bill, Bill Gates, Peter Thiel and Union co-founder collected $ 60 million, including $ 60 million, including investments, including investments David HelgasonAccording to Pitchbook. Satlfoss, ships and Satlfoss agree with Samsung Heavy Industries to set up the designed reactors.

Terrapower

Based on Bill Gates, Terrapower Liquid sodium builds a larger reactor called sodium, which is cooled and melted salt energy storage features.

The company broke his place in the first power plant in Wyoming in June 2024. The sodium design reactor calls on 345 megawatts to produce electricity. This is smaller than other new nuclear plants today, but most SMR is larger than the design.

However, sodium, melted salt carries his arm with a heat storage system. Because the nuclear reactors are best operating in a sustainable situation, the sodium reactor can continue to break the atoms, and additional energy is stored in a heated area, which can be used to produce electricity.

Investors include Gates Cascade Investment Foundation, Xosla Enterprises, CV and Arcelormittal.

Chromium

Chromium landed in a heavy place $ 700 million C-1 series Last year, Amazon was led by the climate pledge fund. At the same time, the SMR started two developments in the Pacific Northwest and the two-west of Virginia to place 300 megawatts of 300 megawatts of Virginia.

The company’s high temperature, gas-chilled reactors, the design of the United States and Europe in favor of other approaches. The company’s XE-100 reactor is expected to produce 80 megawatts of electricity. 200,000 billiards of the helium gas reactor “pebbles” flow to swallow the heat to spin the steam turbine.
