The U.S. government has signed an $80 billion deal with Westinghouse Electric Company to build large-scale nuclear reactors to support growing electricity demand from artificial intelligence.

“Nuclear Spider” sounds like the title of a 1950s-era science-fiction movie, but it’s actually a fairly accurate description of a new robotic system deployed by Atommash, the mechanical engineering division of Rosatom, Russia’s state-owned nuclear utility.
The Canadian provinces of Alberta and Saskatchewan were the subject of two different announcements yesterday about new nuclear developments.
Google DeepMind—Google’s artificial intelligence development subsidiary—recently announced a new partnership with fusion start-up Commonwealth Fusion Systems. The goal of this collaboration is to leverage AI to both advance plasma simulation and discover novel control strategies, ultimately accelerating CFS’s timeline to deliver commercial fusion to the grid.
Here is a recap of recent industry happenings:
New international partnership to speed Xe-100 SMR deployment
X-energy, Amazon, Korea Hydro & Nuclear Power, and Doosan Enerbility have formed a strategic partnership to accelerate the deployment of X-energy’s Xe-100 small modular reactors and TRISO fuel in the United States to meet the power demands from data centers and AI. The partners will collaborate in reactor engineering design, supply-chain development, construction planning, investment strategies, long-term operations, and global opportunities for joint AI-nuclear deployment. The companies also plan to jointly mobilize as much as $50 billion in public and private investment to support advanced nuclear energy in the U.S.
The Department of Energy’s Office of Environmental Management and Office of Science and the National Nuclear Security Administration issued requests for proposals last month, seeking plans from companies to build AI data centers at the Oak Ridge Reservation, the Savannah River Site, and Idaho National Laboratory.

U.K.-based Cavendish Nuclear, a subsidiary of Babcock International, will work with Amentum on the next phase of work supporting the decommissioning of Japan’s Monju prototype fast reactor under a contract awarded by the Japan Atomic Energy Agency.

Over the past several weeks, there has been a lot of activity on the nuclear front in Kansas, ranging from new nuclear sitings to investments.
At a glance: TerraPower signed a memorandum of understanding with Evergy and the Kansas government on small modular reactors; Deep Fission announced investments in Kansas, Utah, and Texas; and the Kansas Board of Regents will invest $15 million in energy projects. Read on to get more information on these items.

After making waves last week at Idaho National Laboratory by breaking ground on its first Aurora Powerhouse reactor, Oklo has again made headlines this week by partnering with Stockholm, Sweden–based advanced reactor developer Blykalla.

Atlanta-based radiation equipment provider Mirion announced that it has entered into a definitive agreement to acquire Paragon Energy Solutions, a leading provider of engineering technology for the nuclear power industry. Mirion purchased Paragon, based in Fort Worth, Texas, from Windjammer Capital Investors for approximately $585 million.

The International Atomic Energy Agency presented its 2025 Global ISOP Innovation Award for AI to Blue Wave AI Labs, Constellation, and the Southern Company subsidiary Southern Nuclear for the companies’ collaborative work on Blue Wave's ThermalLimits.ai. The technology is an AI application that provides accuracy in online thermal limit forecasting for boiling water reactors.

The Nuclear Regulatory Commission will host a hybrid public workshop on September 24 from 9 a.m. to 5 p.m. (EDT) to discuss its activities for the safe and secure use of artificial intelligence in NRC-regulated activities.
New York City–based advanced nuclear technology developer Nano Nuclear Energy has been awarded a Direct-to-Phase II Small Business Innovation Research contract for its Kronos micro modular reactor (MMR) by AFWERX, the innovation and venture arm of the U.S. Air Force. The contract calls for AFWERX, with the 11th Civil Engineering Squadron, to explore the feasibility of deploying the Kronos MMR Energy System at Joint Base Anacostia-Bolling (JBAB) in Washington, D.C.

Nuclearn, the nuclear AI start-up cofounded by Bradely Fox, one of Nuclear News’s 40 Under 40 honorees for 2024, announced it has raised $10.5 million in Series A funding to accelerate product development and market expansion of its AI platform for nuclear plant operations.
Since the Department of Energy kicked off a 10-company race with its Nuclear Reactor Pilot Program to bring test reactors on line by July 4, 2026, the industry has been waiting for new headlines proclaiming progress. Aalo Atomics broke ahead of the pack first by announcing last week that it had broken ground on its 10-MWe Aalo-X at Idaho National Laboratory.
Here is a recap of industry happenings from the recent past:
Progress continues on ITER vacuum vessel construction
Westinghouse Electric Company has signed a $180 million contract with the ITER Organization for the assembly of ITER’s vacuum vessel. Westinghouse has been collaborating with ITER for more than a decade, including in the manufacturing of sectors for the tokamak device’s vacuum vessel, in cooperation with its partners in the AMW consortium, Ansaldo Nucleare and Walter Tosto. After all the vacuum vessel sectors are in place, Westinghouse plans to simultaneously weld the nine sectors to form one circular ring-shaped torus.

Hoping to tackle a growing global demand for energy, The Open Group, a vendor-neutral technology and standards membership organization, has announced the formation of the Industrial Advanced Nuclear Consortium (IANC) to collaborate on finding advanced nuclear energy solutions to serve industrial customers.

Almost every day this week has featured headlines concerning announcements, signings, and progress across Utah’s nuclear sector.
At a glance: TerraPower, Flagship, and the state signed a memorandum of understanding to cooperate on siting a Natrium reactor; $5 million may come to Camp Williams for General Matter–related site preparation work; and Nusano cut the ribbon on a radioisotope production facility.

Less than a week after the news of Fermi America’s first collaboration for its Advanced Energy and Intelligence Campus being built in partnership with Texas Tech University, the company has announced three more industry partners: Parkhill, Lee Lewis Construction, and Westinghouse.
