The UK government will announce changes to planning rules to allow for the construction of more nuclear power plants.
The reform is part of Prime Minister Keir Starmer's plan to grow the economy and reach climate targets.
At present, construction of nuclear power plants is restricted to eight sites in the UK.
Mr Starmer has said that these changes will put Britain back in the race for nuclear energy.
"This country hasn't built a nuclear power station in decades. We’ve been let down, and left behind. Our energy security has been hostage to Putin for too long, with British prices skyrocketing at his whims," he said.
By reforming planning laws, the British government is trying to make it easier to build smaller nuclear plants across England and Wales.
The smaller plants are known as "small modular reactors", and can be built faster than larger, traditional nuclear power stations.
There have been calls for them to be built in Ireland, by think-tanks such as the Irish Academy of Engineering. However, Irish legislation prohibits nuclear power stations.
The UK government hopes that they can help to power new infrastructure, like data centres for artificial intelligence, and make the UK more energy secure.
However, these planning changes will reduce the scope for judicial reviews and change environmental rules.
Environmental groups such as Greenpeace do not support small modular reactors, citing concern over nuclear waste.
There are currently five nuclear power sites in the UK, which are nearing the end of their lifespan. Two new ones are at development stage.
The UK's first nuclear reactor was built in 1947 but a nuclear power station has not been completed since 1995.
The planning changes announced today do not apply to Scotland or Northern Ireland.
