There seems to be no difference between Conservative and Labour policies on nuclear power. Both support the current building of Hinkley Point C in Somerset, the planned Sizewell C station in Suffolk, an unspecified number of small modular reactors all over Britain as well as the far-off dream of nuclear fusion.
However, few scientists serious about the threat of the climate crisis believe new nuclear power stations are part of the solution in reducing carbon output. Building them is too slow and costly, while solar and wind are quicker and cheaper in making a dent in fossil fuel consumption and eliminating it.
