The U.K. government wants nuclear power to meet a quarter of electricity demand by 2050, under plans released Thursday.

Energy Secretary Claire Coutinho said she hoped to usher in a “wider nuclear revival”, which will require nuclear capacity to quadruple over the next 25 years.

Nuclear power generated about 14 percent of total electricity in the U.K. last year, according to the National Grid Electricity Systems Operator. If the government is successful, the country would return to a reliance on nuclear in the energy mix not seen since the 1990s.

A government ‘roadmap’ for the industry, published Thursday, includes proposals for building new power stations, investing in domestic manufacturing of nuclear fuel, and attracting more skilled graduates to work in the sector.

Expanding nuclear power is seen as key to the U.K. reaching its legally-binding 2050 target to hit net zero carbon emissions. Prime Minister Rishi Sunak described nuclear as a “perfect antidote to the energy challenges facing Britain” during this green transition.

Thursday’s plans confirm the government’s ambition to generate up to 24 gigawatts of nuclear power by 2050, despite recent reports suggesting this overarching ambition could be dropped. The plan also includes new interim targets of securing between 3GW and 7GW in investment decisions every five years between 2030 and 2044.

Ministers want to back both large gigawatt plants and small modular reactors (SMRs), which can be built in factories, transported across the country, and reassembled on site.

SMR companies are still competing for government support, while one large scale plant under development — Hinkley Point C — has been hit by ongoing delays and mounting costs. 

The latest proposals will give investors more “certainty of the future direction” of the government’s nuclear plans, the document said. Tom Greatrex, a former shadow energy minister and now chief executive of the Nuclear Industry Association, said the targets would create “greater clarity and predictability” for the supply chain.

The government says it wants to streamline development of new power plants, as well as investing up to £300 million in a uranium fuel plant in north-west England. The plan has also earmarked £10 million to train more nuclear workers.

A spokesperson for the opposition Labour Party said that the government was two years late delivering its nuclear plan. “The British people should be going full pelt for clean power, but the Tories' woeful record is holding us all back,” they added.
