UK government sets out plans for ‘biggest nuclear power expansion in 70 years’

Ministers hope to build fleet of reactors to meet quarter of electricity demand by 2050 but critics highlight long delays and rising costs

The government has set out plans for what it claims will be Britain’s biggest nuclear power expansion in 70 years, despite concerns about faltering nuclear output and project delays.

Ministers published a roadmap on Friday that recommits the government to building a fleet of nuclear reactors capable of producing 24GW by 2050 – enough to meet a quarter of the national electricity demand.
