An Amazon-backed small modular nuclear reactor company is filing for an initial public offering amid rising investor interest in nuclear energy. X-energy submitted a draft registration statement to the Securities and Exchange Commission on Friday, putting it on track to go public sometime in the early summer. The IPO would be the latest for developers of small modular nuclear reactors, which have been touted as a potential solution for rapid electricity demand growth caused largely by data centres, but also the electrification of cars and household appliances. According to data from BloombergNEF, US data centre power demand is set to climb from 34.7 gigawatts in 2024 to 106GW by 2035. X-energy is building an SMR that uses helium as a coolant instead of water, the industry standard. Supplies of helium have been severely disrupted by the effective closure of the Strait of Hormuz amid the Iran war, pushing up commercial prices. “Spot helium prices could spike by 50 per cent to 200 per cent in severe shortage scenarios,” according to Fitch analysts. Amazon backed the company in October 2024, anchoring a $400mn fundraising round along with Citadel’s Ken Griffin. The ecommerce giant took two seats on the company’s board. In November X-energy completed a $700mn fundraising round led by Jane Street, ARK Invest, Galvanize, Hood River Capital Management, Point 72, Reaves Asset Management and XTX Ventures. In addition to Amazon, it has secured contracts with FTSE 100-listed Centrica and Dow. While X-energy has not received full approval from the Nuclear Regulatory Commission to build its reactor, in February the agency licensed the company to make nuclear fuel for advanced reactors at a facility in Oak Ridge, Tennessee. X-energy declined to state how much it is seeking to raise, or how its shares would be priced. JPMorgan, Morgan Stanley, Jefferies and Moelis and Company are acting as the lead bookrunners. X-energy would be the fourth publicly traded SMR company, following Nano Nuclear, NuScale Energy and Sam Altman-backed Oklo. Oklo’s stock price has gained 94 per cent over the past year. But Nano and NuScale have lost ground, falling 32 and 27 per cent respectively. Recommended The Big Read The cost of America’s nuclear revival The filing comes as Wall Street investment bankers are gearing up for a series of potentially huge listings later this year. Elon Musk’s rocket group SpaceX and AI start-ups Anthropic and OpenAI have all indicated plans to go public at some point in 2026. Each of the three deals is expected to raise tens of billions of dollars in proceeds, potentially outstripping the total haul from about 200 US IPOs in 2025. Market volatility triggered by the war in Iran could yet scupper bankers’ pipeline, however, just as the economic turmoil sparked by President Donald Trump’s so-called liberation day tariffs last April put several large US tech listings on pause.

Nuclear's cleanup cost threatens the expansion dream

Countries are racing to build new reactors. But we've barely figured out how to clean up the old ones — and the bill is potentially staggering.

My new book -- No to Nuclear

Greetings everyone.

My book -- No to Nuclear. Why Nuclear Power Destroys Lives, Derails Climate Progress and Provokes War -- is now officially published in the US. You can order a copy here.

https://www.plutobooks.com/product/no-to-nuclear/

I can offer you a special discount of 30% off for members of this list. Use NUCLEAR30 to receive it.

The goal with this book is for you to purchase to give to someone else -- a relative, friend, colleague who may be on the fence or even pro-nuclear.

It's hopefully a comprehensive indictment of the many reasons to oppose nuclear power (and nuclear weapons), so by the time a reader is finished, he/she will have been convinced by one argument or another -- or all of them put together!

If you would like to do an in--person event or webinar with me about the book, please get in touch.

All the best,

Linda

Community Kayak to Protest Savannah River Site Plutonium Pit Production – March 28

AUGUSTA, GA (March 19, 2026) — A coalition of local groups are hosting a day-long “Paddle and Boogie to Stop the Bomb” event on the Augusta Canal next to the Savannah River to advocate against the production of plutonium pits for nuclear weapons and to share information about the radiation contamination risks of the Department of Energy’s (DOE) Savannah River Site (SRS) ahead of upcoming public hearing and comment periods.

Participants will paddle 5.5 miles in the morning from Savannah Rapids Park in Martinez to the Mill Village Trailhead in Augusta, where there will be an afternoon gathering with live music, educational information and more fun activities.

Background:

SRS is a 310-square-mile site near Aiken, SC, that was produced plutonium and tritium for use in nuclear weapons from the 1950s to the 1990s. The plutonium was shipped to Rocky Flats, CO, where it was turned into plutonium pits. Rocky Flats was shut down and designated as a Superfund site in 1989 after investigations found significant radioactive environmental contamination.

With little public discussion or notice, the Department of Energy (DOE) determined it would produce new plutonium pits at SRS. After a lawsuit, a 2024 court ruling found that DOE violated the law under the National Environmental Policy Act by failing to complete a new and comprehensive programmatic environmental impact study that fully considers the effects of producing plutonium pits for nuclear weapons at SRS and Los Alamos Nuclear Laboratory.

DOE and the National Nuclear Security Administration (NNSA, semi-autonomous agency within DOE) are due to release the required programmatic environmental impact study in the coming weeks. There will be a 90-day public comment period, and a series of five court-mandated public hearings, including one in Aiken, SC. The previous PEIS for the plutonium program, in 2008, provoked more than 100,000 public comments.

Event Details:

Paddlers will meet by Savannah Rapids Kayak Rental (Savannah Rapids Park, 7 Savannah Rapids Trail, Martinez) at 9 a.m. ET, and depart by 10 a.m. for Mill Village Trailhead on the Augusta Canal (109 Eve St., Augusta), with live solar-powered music headlined by roots rock reggae band Natti Love Joys and fun educational events beginning at 1 p.m. Bring your own kayak or rent one (mention Paddle and Boogie for a discounted rental). There will be a shuttle back to the starting point for paddlers.

The event is co-hosted by Nuclear Watch South, Savannah River Site Watch, Georgia WAND, the Savannah River Group of the Georgia Chapter of the Sierra Club, the Carolina Peace Resource Center, Savannah Rapids Kayak Rental, and the Generational Radiation Impact Project.
