With the Hinkley Point C project, AREVA NP is set to participate in one of the major industrial projects of the coming decade. By 2020, the British government will be embarking on a program to replace its nuclear fleet. The utility EDF Energy, a subsidiary of EDF, is going to build two EPR reactors on the site of Hinkley Point. The two Hinkley Point C EPR reactors will provide reliable, low-carbon electricity that will meet approximately 7% of the UK's electricity needs.

Britain is considering extending its nuclear program with the development of 2 other EPR reactors at Sizewell C in Suffolk.

    The customer

    The customer is NNB, the structure created by EDF Energy, EDF's UK subsidiary, for the Hinkley Point C project.

    The shareholder structure within NNB will be as follows:

    - EDF Energy: 65%

    - China General Nuclear Corporation: 33,5%

  • The contract

    The contract

    Net electric output: 2 x 1,600 MWe

    Reactor thermal output: 4,500 MWth.

    NNB is responsible for the overall project management.

    NNB is the project owner.

    In all, some fifty British companies have been identified as potential suppliers for this project.

    In 2012, AREVA signed partnership agreements with 25 local businesses as part of its planning for the construction of the two EPRTM reactors.

  • AREVA NP supply scope

    AREVA NP supply scope

    AREVA NP is responsible for all cross-cutting activities involved in the execution of the nuclear steam supply systems and the instrumentation and control system:

    • Design and supply of two nuclear steam supply systems,
    • Erection and commissioning,
    • Design and supply of the digital Instrumentation & Control (I&C) systems:
      • Safety I&C
      • Operational I&C
      • Simulator

  • Licensing

    Licensing

    Initially, the British regulatory authorities HSE, ONR and EA assessed the EPR™ reactor in terms of nuclear safety, occupational safety and the environment. A Generic Design Assessment (GDA), part of the licensing process, was followed.

    Following a detailed review of the EPR™ reactor’s design and instrumentation and control system, particularly from a post-Fukushima perspective, the regulatory authorities gave their consent on December 13, 2012 for the design of the reactor in the United Kingdom.

    In fact, the EPR™ reactor was the first and is the only Generation III+ reactor to be certified by the safety authorities in the United Kingdom.
