About
Copenhagen Atomics

Copenhagen Atomics was founded in 2014 by Thomas Jam Pedersen, Peter Szabo, Thomas Steenberg and Aslak Stubsgaard, all with a technical background and relation to Technical University of Denmark.

Right from day one, the goal was to make thorium energy at a lower cost than any other energy source and enable fast deployment of this new reactor design.

We started Copenhagen Atomics with the belief that humanity’s main limitation is how much energy we can access.

Above, from left to right, are Thomas Steenberg, Peter Szabo, Thomas Jam and Aslak Stubsgaard, the four founders of Copenhagen Atomics.

What makes us special

Copenhagen Atomics presents a new reactor design, with different physics than all other previous reactor designs, resulting in much lower energy price and less materials used.

Because of the profound difference between Copenhagen Atomics reactors and all other reactors, Copenhagen Atomics also introduces a new business model:

Business model

Copenhagen Atomics will finance, build, own and operate the reactors on the customer site. The resulting energy prices are expected to be ¼ of the typical price from classic nuclear reactors.

The Waste Burner concept

In addition to radically lower energy prices, this new type of reactor can also use “waste” from classic nuclear reactors, extracting ten times more energy out of this spent nuclear fuel than what the initial reactor was able to extract.

Additionally, the waste left behind by the Copenhagen Atomics reactor only needs to be stored for 300 years above ground, vs. 100,000 years of deep geological storage for nuclear waste from traditional reactors. 

Copenhagen Atomics already has agreements in place about waste handling.

The reactor

The reactor type invented by Copenhagen Atomics is a thorium molten salt breeder reactor, which fits inside a custom built 40 foot shipping container and can be mass manufactured on assembly lines with an expected output of minimum 1 reactor per day (per assembly line).

The target customers are large plants producing commodities such as aluminium, ammonia or hydrogen.

The founders were inspired to start the company because of previous work by Alvin Weinberg, Kirk Sorensen and many others.

We believe thorium energy is going to supply more than half of all energy to humans before the year 2100. This is how big this opportunity is.
