The customer

The EDF group is an integrated energy company operating in all branches of the industry: generation, transmission, distribution, and the trading and sale of energy. The Group is the largest electricity producer in Europe.

In France, it has predominantly nuclear and hydroelectric power plants supplying electricity that is 95% CO2-free. In total, EDF generated 470.2 TWh in 2010 in France.

Since the nineteen-seventies, EDF has designed, built and operated 58 pressurized water reactors (PWR) totaling 63.1 GW in installed capacity and spread across 19 sites throughout France (thirty-four 900 megawatt reactors; twenty 1,300 megawatt reactors; four 1,500-megawatt reactors) and accounting for more than 85% of the electricity generated by EDF.
All 58 reactors, built by AREVA, were commissioned over the period spanning 1977 to 1999.

Licensing process

Flamanvielle 3 is proceeding through a rigorous two-step French licensing process. This licensing process is being conducted in parallel with project execution under the client’s responsibility, interfacing with the French regulatory body ASN.

The French government granted the construction license for Flamanville 3 on April 11, 2007, on the basis of a comprehensive analysis of the EPR™ design.
The Preliminary Safety Analysis Report (PSAR) was presented in 2004 and the final submittal is planed for October 2010.

A continuous production of project documents for surveillance and approval by safety authorities in the areas of design engineering, manufacturing, construction, commissioning is being conducted throughout the implementation of the project.
Provisional Final Safety Analysis Report will then be approved, which authorizes the fuel loading and further start-up activities.
