Is the UK’s giant new nuclear power station “unbuildable”?

 The design of the UK’s latest nuclear power station is “terrifying”,
“phenomenally complex” and “almost unbuildable”, according to Henri
Proglio, a former head of EDF, the French state-owned utility behind the
project.

One month after the final green light for Sizewell C, 1,700
workers are on site in Suffolk, on the UK’s east coast, preparing the
sandy marshland for two enormous reactors that will eventually generate
enough electricity for 6mn homes. The plant will be a replica of the
European Pressurised Reactor (EPR) design that is running four to six years
late and 2.5 times over budget at Hinkley Point C in Somerset, which has
had problems wherever it has been built, in France, Finland and China.

But unlike at Hinkley, where EDF was responsible for spiralling costs and took
a hit of nearly €13bn after running late and over budget, the UK
government and bill payers are on the hook for Sizewell. The state will
provide £36.5bn of debt to fund the estimated £38bn price tag and be
responsible if costs go beyond £47bn

“Being able to build an EPR in the
timeframe, with the planned costs? I don’t think so,” Proglio, a critic
of the design, told the Financial Times. “The EPR is a machine that is
phenomenally complex to build, with more rebar than concrete, it is
terrifying . . . it’s almost unbuildable. As long as the design has
not changed, the difficulty of building will not have changed either.”
