France - Flamanville 3
Flamanville 3 is the first Generation III+ plant in the new French reactor fleet and the 100th reactor order placed with AREVA worldwide.
French authorities and utilities launched their nuclear renaissance program keeping in mind 2020, when the country’s original fleet of nuclear power plants will start to enter the decommissioning phase.
Customer: Électricité de France (EDF)
Supply scope: 1 EPR™ unit Nuclear Steam Supply System (NSSS)
Net electric output: 1,630 MWe
Reactor thermal output: 4,300 MWth
Signature date: April 17, 2007
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.

AREVA Supply chain
Flamanville 3 projects requires a globally qualified industrial supply chain and pool of subcontractors: around 100 suppliers will be working for AREVA on the project.
Manufacturing responsibilities are as follows:
MAIN EQUIPMENT PRIMARY CIRCUIT WORK
- Steam generator and pressurizer: AREVA Châlon/Saint Marcel (France)
- Reactor coolant lines: AREVA Creusot Forge (France)
- Reactor coolant pumps: AREVA Jeumont Solutions for Pumps and Mechanisms (JSPM), France
- Control rod drive mechanisms: AREVA JSPM, (France)
- Reactor pressure vessel: Forging at Japan Steel Works (JSW) in Muroran, Japan, and Manufacturing at AREVA Chalon Saint Marcel, France
> At peak: about 540 AREVA engineers are working on the project
Construction site staff
> At peak: 2,500 employees, of which 400 AREVA employees and suppliers
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.

EPR™ Safety Robustness
The EPR™ technology offers the most advanced level of safety, able to face unlikely events such as what happened in Japan. This video demonstrates the robustness of the EPR™ design, using a combination of redundant, diverse and complementary safety systems.
