Copenhagen Atomics pioneers thorium molten salt reactors, a solution that burns nuclear waste to generate abundant and cost-effective green energy

[Copenhagen Atomics @CphAtomics]

Building towards a new era of human progress isn’t just about physics.

Thorium molten salt reactor technology represents an engineering leap toward cheap, reliable and independent industrially-scalable global energy.

This week in Zug, we joined forces with the Zug Institure for Blockchain Research (ZIBR) and @hslu Hochschule Luzern for an insightful session bridging the gap from development to real-world deployment.

Our “Research meets Practice” panel explored the critical levers required to bring a new generation of reactors to market: bold regulatory frameworks, rapid licensing, and mass standardisation.

A massive thank you to our co-hosts and panelists and presenters Marco Streit from @psich_en Paul Scherrer Institute, Juste Dilyte, Tim Weingärtner, Max Baumgart and Tim Kilcher, as well as all attendees pushing these key conversations forward.

Special thanks to @CV_Labs (Fabiola Luna Huerta, Jelena Jesin, Charlie Papamichael) for hosting us, and to our HSLU “partner in crime” Sabrina Wollenschläger.

The future of energy is being built now. ⚛️
More power. More possibilities to the people.

Thorium has held extraordinary promise for nuclear energy for decades. So why aren't we using it?
That's the question Dr. Ben Miles set out to answer when he visited us.

Over the past 12 years, our team has been working to turn the potential of thorium molten salt reactors into a practical, commercially viable energy technology designed to deliver the lowest cost of electricity.

From tackling corrosion through salt purification to developing lithium-7 enrichment capabilities and designing reactors for industrial mass production, our approach is built around solving the engineering challenges that have held thorium back for decades.

Unlocking thorium's potential is only part of the challenge. Nuclear energy also has to be faster to deploy and able to scale to meet growing global demand. That is what our reactors are designed for.

In his latest video, Ben takes an in-depth look at our technology, the progress we've made, and the challenges that still lie ahead.

A big thank you to Ben for visiting our facilities in Copenhagen and taking the time to explore the science and engineering behind our work.

101 people. One shared ambition: changing how nuclear energy is produced.

Building a new generation of nuclear reactors takes more than an ambitious idea. It takes engineers, scientists, technicians and specialists working across disciplines to turn that idea into working technology.

Civilisation runs on energy. Every great leap in human history began with more of it, and the future demands far more than the world can produce today. At Copenhagen Atomics, we're developing thorium molten salt reactors designed to make far more efficient use of nuclear fuel. Thorium holds enormous untapped energy potential, and our ambition is to harness it through reactor technology that can be manufactured and deployed at scale.

Physics defines what is possible. Engineering makes it real.
Reaching 100 employees is a vital milestone for us. It reflects how far we’ve come and the industrial capabilities we are scaling to bring thorium molten salt reactors to market. Energy is more than electricity; it is independence, sovereignty, and the foundation of human progress.

To everyone who has helped build Copenhagen Atomics into what it is today: thank you.

And to the team of 100 making the next chapter possible: we don't just build power, we build possibility.

Energy = Prosperity.

We've purchased low-enriched uranium from @urencoglobal for our first reactors. And we're working together to establish the fuel conversion capabilities those reactors will need. We have signed a Memorandum of Understanding to collaborate on the development of a uranium deconversion facility in Copenhagen.

Why does this matter?

Low-enriched uranium is supplied as uranium hexafluoride (UF₆). Our molten salt reactors require uranium tetrafluoride (UF₄) for fuel-salt production.

The proposed facility would enable that conversion, creating an important link between uranium enrichment and molten salt reactor fuel production.

Our ambition extends beyond our own reactors. We aim to develop fuel production capabilities that can also support other molten salt reactor developers and research institutions.

We're building the reactor technology, manufacturing capabilities and fuel infrastructure needed to bring molten salt reactors to market at scale; and fundamentally change how nuclear energy is produced.

Nuclear power plants can take a decade to build. We're working to fundamentally change that.

At our Copenhagen R&D facility, construction is underway to prepare for the first version of our Cocoon: a modular steel containment structure intended to house our #thorium molten salt reactor unit; designed for mass manufacturing, offering an alternative to the massive, reinforced concrete containment buildings used in conventional nuclear power plants.

The latest milestone? Concrete is being poured and trenches are being prepared to accommodate the structure.

The Cocoon consists of 18 prefabricated steel sections designed for conventional truck transport and rapid on-site assembly using standard lifting equipment.

By replacing bespoke on-site construction with standardised industrial manufacturing, we aim to significantly reduce construction costs and accelerate deployment.

The Cocoon is one part of our wider ambition to make nuclear energy faster to deploy, scalable through industrial manufacturing, and ultimately competitive with the world's lowest-cost energy sources.

AI needs massive, reliable clean energy to scale. ⚡

Copenhagen Atomics CEO Thomas Jam Pedersen presented last week at @SwissRe's Engineering Underwriting Forum 2026 highlighting how containerized thorium molten salt reactors can unlock base-load power for data centers.

Copenhagen Atomics in the Swiss press 🇨🇭

Swiss leading newspaper SonntagsZeitung has featured Copenhagen Atomics in an in-depth article by Mischa Aebi exploring our technology, our ongoing work with the Paul Scherrer Institute (PSI), and our expansion into Switzerland.

As Switzerland prepares for an important national discussion on the future of nuclear energy, the piece highlights our ambition to industrialise nuclear energy through scalable, factory-manufactured thorium molten salt reactors.

To be clear: we are not relocating our headquarters to Zug (yet) - instead, we are establishing our commercial operations there to anchor ourselves in Switzerland’s exceptional engineering and innovation ecosystem.

What would it take to produce ten times more energy than today? ⚛️

At the Paul Scherrer Institute colloquium, our CEO Thomas Jam Pedersen explained why the answer runs through thorium: the only route to breeding in a thermal spectrum, at a raw fuel cost more than 1,000x below solid uranium fuel.

Here's why👇 https://t.co/nfO5LvtAw8

Human progress requires abundant energy, but clean energy debates are stuck in political confusion.
It’s time to look at the machines themselves.
Here is what a Molten Salt Reactor actually is—and why it’s the tech we need. 👇

@SpaceElevator7 It is. But it is also much more expensive.

[Copenhagen Atomics @CphAtomics]

Did we just solve the corrosion challenge in molten salt reactors?

Our experiments show that corrosion drops dramatically when molten fluoride salts are highly purified. In tests with the University of Liverpool, stainless steel showed very low corrosion rates even at very high temperatures.
