For decades, fusion has been the alchemy of our technological age. So, how feasible is the UK’s plan to build a commercially viable fusion power plant by 2040? However, building a fully working, commercially-viable, fusion reactor in 20 years is a colossal undertaking. For comparison, the Hinkley Point C nuclear fission reactor is expected to be completed by 2025. It will have taken 15 years, from proposal to completion, and will use existing nuclear fission technology that has been around since the 1950s. Meanwhile, the Iter fusion reactor in France is currently 70% constructed and is expected to achieve first plasma in 2025. This is will be a fully-working demonstration fusion reactor, providing 500 megawatts of fusion power – enough, if converted to electricity, to power a city the size of Liverpool.
