What is Sizewell C – and why is it so controversial?

The UK is 1 measurement person to a caller atomic powerfulness works aft the authorities announced a further £14.2bn successful funding.

Sizewell C, adjacent the municipality of Leiston connected the Suffolk coast, is owed to beryllium up and moving by the mid-2030s.

But high-profile atomic accidents, though incredibly rare, person leaked deadly radiation into the atmosphere, sidesplitting radical and apt poisoning others for generations to come.

These see the detonation astatine the Chernobyl works successful Ukraine successful 1986 and the partial meltdown of 1 of the reactors astatine the Fukushima atomic works successful Japan pursuing a tsunami successful 2011.

What are the arguments for it?

The authorities wants to usage atomic vigor to assistance conscionable its people of nett zero greenhouse state emissions by 2050.

Since then, Ukraine's Western allies person made efforts to go much autonomous with vigor production.

Britain's atomic assemblage grew by a 4th to £20bn successful the 3 years to 2024, with different tract astatine Hinkley Point successful Somerset presently nether construction.

Some countries, similar France, wherever EDF is based, already trust heavy connected atomic power.

Sizewell C volition besides make 10,000 caller jobs and 1,500 apprenticeships, boosting the section and UK economy.
