Simone Rossi, the new CEO of EDF Energy, has said the new £19.6bn project will be built on time.
During a visit to the construction site, Rossi told workers that progress was going well and the project was ”on track”.
Rossi said: “Today there are almost 3,000 people on the site and there will soon be more than 5,000 working there, on a project that is on track for its next big milestones.
“We’ve moved more than four million cubic metres of earth – that’s like digging a hole two and a half times as big as the Millennium stadium in Cardiff. We are already installing the huge sea water cooling pipes. Soon the boring machines will arrive for the 11kms of tunnels which will be dug under the Bristol Channel.”
Balfour Beatty are undertaking the tunnelling work for the project.

Rossi added that building a new nuclear power station at Sizewell could be 20% cheaper than Hinkley Point C site because “doing something again with the same design makes it easier and cheaper”.
For example new emergency generators would not need to be designed and certified again, reducing the overall cost of the project, he explained.
“Repeating that experience countless times for a power station at Sizewell that is largely identical to Hinkley Point C makes a capital cost reduction of 20% possible” he added.
The aim remains to put the first unit of power into service at Hinckley Point by 2025.
