Newcleo is developing the latest generation of nuclear reactors providing a path to combatting both climate change and existing nuclear waste. It is working on so-called Small Modular Reactors (SMRs) and wants to use so-called MOX technology to make it possible to recycle spent uranium from conventional nuclear power plants.
