Provide Affordable Energy from Thorium Molten Salt Reactors
Copenhagen Atomics will mass manufacture thorium molten salt reactors
Already in the early 2030s, we are likely to have installed capacity and speed that exceed any other nuclear company.
The first gigafactory will be able to install 15–50 GW of capacity per year.

Building, Testing, and Proving
Copenhagen Atomics has built more hardware and conducted more testing than most other nuclear companies.
Our molten salt reactor prototypes are tested under real operating conditions, not simulations.
We have already built two full-size reactor prototypes and are now building the third non-fission prototype.
Copenhagen Atomics plans to run its first nuclear chain-reaction at the Paul Scherrer Institute (PSI) in 2028. The Swiss national nuclear Lab.
We make the best work of our lives
At Copenhagen Atomics you will find people with real skills, building and solving engineering challenges with our own hands.
We chose tools and work processes that optimize result and minimize bureaucracy. Eg. using short voice messages and not long meetings. You will find engineers and top management working on the actual products in the workshop, innovating together.

Fixed price per reactor unit
Each thorium molten salt reactor unit is currently priced at $50M, all-in, no overruns.
Copenhagen Atomics will build the reactors and supply the fuel for an one time upfront cost of $50M plus $2M / year for each reactor unit, ensuring transparency and no cost overruns. Our customer is the nuclear power plant owner.
Days of testing
The shortest route to a reliable product is lots of testing. So far, we’ve accumulated more than 160.457 days of testing on the components for our first reactor.
From
2019 – now
I expect more than half of all global energy by 2100 to come from thorium. Why? Because price is king.

Ready to disrupt a trillion-dollar industry?
Until today, human-kind has only built nuclear reactors in the circle and triangle category.
Copenhagen Atomics is going to be the first ever to build reactors in the right column of this chart (pentagon). This will disrupt the entire global energy sector, with unbelievable low energy prices and fast deployment.

Frequently Asked Questions
What is Copenhagen Atomics?
Copenhagen Atomics is a Danish nuclear energy company building thorium molten salt reactors for mass manufacturing. Founded in 2014 and based near Copenhagen Airport, the company has 75 engineers, has built two prototype reactors, and targets electricity at below $20 per MWh. The first 1 MWth test reactor is expected to be operational by 2028.
What is a molten salt reactor?
A molten salt reactor (MSR) uses liquid salt as both the fuel carrier and the coolant, instead of solid fuel rods and pressurised water. The reactor operates at atmospheric pressure, which removes the risk of a pressurised steam explosion. Higher operating temperatures also make the energy conversion more efficient than conventional light water reactors.
Why does Copenhagen Atomics use thorium?
There is roughly 1000 times more thorium in the Earth’s crust than usable uranium 235 and produces far less long-lived radioactive waste. In a Copenhagen Atomics reactor, the raw fuel cost is approximately $2.22 per GWh of thermal energy, versus $2,000 to $8,000 per GWh for conventional solid uranium fuel. Thorium also enables a breeding fuel cycle, meaning the reactor generates more fissile material than it consumes over time.
When will the first Copenhagen Atomics reactor be ready?
The first 1 MWth test reactor is planned to be operational by 2028. Commercial reactors producing 100 MWth per unit are planned for the early 2030s. Copenhagen Atomics has already completed two prototype reactors and expects to complete a third in 2026.
How much does a Copenhagen Atomics reactor cost?
The current target price per reactor unit is $50 million per 100 MWth unit. In addition to a $2 million annual service fee for running replacement of components and refueling. Over a 50-year plant lifetime at a 90% capacity factor, this works out to approximately 9 USD/MWh (electric) paid to Copenhagen Atomics.
Can I invest in Copenhagen Atomics?
Yes. Copenhagen Atomics is a private company with over 200 investors from 20 countries. Pre-IPO shares are available through secondary trades from existing shareholders. Professional investors with EUR 100,000 or more can participate directly in new share issuances. Contact the investor relations team via the Invest page.
Where is Copenhagen Atomics based?
Copenhagen Atomics is headquartered at Oliefabriksvej 77, 2770 Kastrup, Denmark, close to Copenhagen Airport. The facility houses both the engineering team and the company’s active molten salt test loop infrastructure.
