newcleo is a clean and safe nuclear technology company. Privately funded and headquartered in London, UK, newcleo was launched in 2021 to be a disruptor in the field of nuclear energy. Its mission is to generate safe, clean, economic and inexhaustible energy for the world, through a radically innovative combination of existing, accessible technologies.

newcleo is building the next generation system with the goals to:

  1. eliminate the need for geological repositories by using a fast neutron flux avoiding the production of long life radioactive elements;
  2. accelerate the development of new fuel cycles, including MOX (Mixed Pu-U Oxides) and eventually thorium, that provide clean, safe and inexhaustible energy from nuclei and the opportunity to burn the long-lived nuclear waste produced by the old generation of nuclear reactors;
  3. ultimately develop an Accelerator Driven System (ADS), based on the intrinsically safe coupling of a particle accelerator and a sub-critical reactor.

With visionary co-founders, newcleo brings together an international team of senior engineers with deep knowledge of nuclear energy and new recruits with a fresh mindset, working to develop designs based on innovative Lead-cooled Fast Reactors (LFRs). These LFRs will meet the commercial demand for small terrestrial waste-to-energy reactors.

In the UK, newcleo’s immediate focus is on delivering a prototype 30MWe LFR by 2030 followed by an initial battery of 4-6 x 200MWe reactors with deployment in the early 2030s. We are building our team to meet this challenging and exciting objective.

newcleo wants to be the first step toward the evolution of its industry to become fully respectful of people and the environment. To develop a new, sustainable, and completely safe way of generating nuclear energy that will lead humanity to zero emissions, and to the mitigation of global warming.
