Developing a new industrial standard of clean, safe and inexhaustible energy production from Nuclei MoreLess
Newcleo is a company that designs and builds the next generation of nuclear reactors, the lead-cooled fast reactors (LFRs) fuelled with MOX. These reactors are an innovative way to provide the world with a safe and stable power source while reducing volumes of nuclear waste. This type of nuclear technology has recently been included within the perimeter of the EU Taxonomy of environmentally sustainable economic activities, by the EU Commission.
Newcleo is different from other businesses in the same industry because of the key characteristics of their projects. These include the use of lead fast reactors and the use of MOX. They are also looking to recruit talented people to join their growing community of energy innovators, so they can continue to innovate and create new solutions for global decarbonisation.
Newcleo is a profitable business that is making a difference in the world. They are helping to reduce the impacts of climate change and are providing a safe and reliable energy source. This is helping to create a better future for everyone.
