The most powerful reactor worldwide

The EPR reactor has been designed with the highest standards of safety as well as optimized technical, economic and environmental performance

EPR1200, the EPR mid-size adaptation

Entirely based upon the fully proven EPR design, the EPR1200 benefits from EPR’s robustness at a power output of 1200 MWe (instead of 1650), with the highest standards of safety as well as optimized technical, economic and environmental performance.
The EPR1200 is adapted to various site and grid conditions.

The EPR reactor: cutting-edge, safe, respectful of the environment

Benefitting from unrivalled operating performance, EPR is the only Generation III+ nuclear reactor in the world, already licensed by four recognised nuclear authorities: in France, the United Kingdom, Finland and China.

  • ✓ A proven technical configuration for Generation III+ reactors resulting from 60 years of experience and mature PWR technology

  • ✓ Nuclear safety is our overriding priority and is at the forefront of what we do

    ✓ A GEN III+ technology with the highest standards of safety with strong resistance:

    • Design taking into account external extreme hazards
    • Post-Fukushima requirements integrated in the design
    • Resistance to severe accident as per design: very low frequency of severe accident
  • ✓ Outstanding operating performance with an availability over 90%

    ✓ An unbeatable flexibility thanks to load-following: capacity to adjust its power up to 80% in 30 minutes twice a day as per design

    ✓ A highly dispatchable solution with an availability 24 hours a day 7 days a week on demand

    ✓ A high degree of localisation to boost our clients’ economy

  • ✓ Carbon-free electricity generation avoiding 10,5 million tonnes of CO2 emissions per reactor per year

    ✓ Biodiversity preservation thanks to a limited land footprint and high energy density

Building a long-term partnership

EDF manages the entire nuclear power plant lifecycle:


A potential of more than 30 EPR reactors by 2050

With a potential of more than 30 EPR reactors across the world, EDF is fully engaged in nuclear new build activities and is committed to supporting its domestic program as well as several countries in their nuclear development.
