UK and US unveil nuclear energy deal ahead of Trump visit4 hours ago Share Save Charlotte Edwards & Dearbail Jordan Business reporters Share SaveGetty ImagesThe UK and US are set to sign an agreement focused on accelerating the development of nuclear power. The key focus of the so-called Atlantic Partnership for Advanced Nuclear Energy is to make it quicker for companies to build new nuclear power stations in both the UK and the US. The UK's nuclear programme already includes plans for small modular reactors (SMRs), which are a scaled-down version of larger plants. Unlike SMRs, which are water-cooled nuclear reactors, advanced modular reactors use gases such as helium as a coolant. But Greenpeace questioned the UK's focus on nuclear power.
