Name of the Project
Flamanville 3 European pressurised reactor (EPR) project.

Location
Normandy, France.

Project Owner/s
Multinational electric utility company Électricité de France (EDF).

Project Description
The Flamanville EPR is the first nuclear power station to be built in France in the past 15 years and the first third-generation-type plant. The nuclear plant will have a net electricity output of 1 650 MWe.

Potential Job Creation
Not stated.

Capital Expenditure
The project has been beset by cost increases. In October 2019, EDF said the necessary repairs to the reactor's main secondary system penetration welds would further increase the cost of building the Flamanville EPR, from an estimated €10.5-billion to €12.4-billion.

Planned Start/End Date
Construction work began in December 2007.

Connection to the national grid is scheduled for the second half of 2024.

Latest Developments
The Flamanville 3 reactor was connected to the national grid on December 21, 2024, and has produced 100 MW of electricity.

Following this initial coupling, in accordance with startup operations, the phases of testing, and of connection and disconnection to the grid, will continue for several months under the supervision of the ASN, until the reactor reaches 100% power.

Starting up a reactor is a long and complex operation. It requires the full mobilisation of teams and is conducted with the highest level of safety and industrial reliability at every stage.

The volume of electricity produced from the first coupling until the first scheduled maintenance shutdown and fuel reload (Control Visit No 1) is estimated at about 14 TWh.

Key Contracts and Suppliers
Areva (nuclear steam supply system); Bouygues (civil work); and Alstom (turbine island).
