Huge dome lifted onto Hinkley Point C nuclear reactor

A 245-tonne dome has been lifted onto a reactor building at the first nuclear plant to be built in Britain for 30 years.

EDF Energy said twin nuclear reactors at Hinkley Point C in Somerset would provide zero-carbon electricity for more than six million homes in Britain when the site opened.

The second dome was installed earlier using a “build and repeat” method, using off-site prefabrication and experience from installing the first dome on the first reactor.

The site is projected to open in 2031, according to EDF, which is five years later than originally planned.

Work on Hinkley Point C’s second reactor building was stopped during the pandemic but EDF said teams were using time-saving methods to catch up.

Stuart Crooks, CEO of Hinkley Point C, said: “Restarting the industry has been hard, but the second of our two identical units shows the big benefits of repeating an identical design.

“The build and repeat method is the best way to build new nuclear with time savings already at 20-30%.”

Energy minister Michael Shanks added: “Hinkley Point C will deliver the next generation of clean, homegrown nuclear power, creating high quality jobs and growth in Somerset and across its supply chains.”
