For each reactor, Eiffage will build several dozen of buildings, including the giant concrete domes containing the reactor, the turbine halls and a six-level operation building.
The deal for the would-be EPR2 reactors state-owned utility EDF is building at its Penly site in northern France, will involve almost 4,000 people and generate 1.3 million working hours, Eiffage said.
Preparatory works are due to start in mid-2024, once EDF has obtained all necessary permits to kick off the construction.
