The massive costs and long construction times associated with nuclear power means that every euro invested delays decarbonisation. Since the crisis we face is urgent, the wise approach is to prioritise the transitions that are cheapest to build and fastest to deploy.

The fact that we have to take everything about SMR technology on trust is important because for almost a century, the unfulfilled promise of the nuclear energy industry has left a trail of destruction in its wake. While carbon-neutral from a certain perspective, any claim that nuclear energy has been good for the environment can only be financially motivated. Apart from the obvious catastrophic impact of the Fukushima and Chernobyl disasters, in the ten years from 2006-2016, Greenpeace found 166 “near misses” at nuclear power plants in the USA alone.
