Le réacteur EPR™, le premier d'une nouvelle génération de réacteurs au Royaume-Uni.

AREVA a franchi une étape majeure pour la construction des réacteurs EPR™ au Royaume-Uni en signant avec EDF un protocole d'accord portant sur la livraison de chaudières nucléaires et de systèmes d’instrumentation et de contrôle commande pour le projet d’Hinkley Point C in February 2012. (en anglais)

  • Deux réacteurs EPR™ sur le site nucléaire d' EDF à Hinkley Point C
  • Contrat

    Le contrat

    Customer: EDF Energy.

    Supplier: AREVA.

    Supply scope: 2 EPR units Nuclear Steam Supply System (NSSS).

    Net electric output: 2 x 1,600 MWe.

    Reactor thermal output: 4,500 MWth. 

  • Client

    Le client

    For the project, EDF, via its UK subsidiary, EDF Energy with its partner British utility Centrica, plans to construct:

    • two nuclear power plants based on EPR™ technology at the Hinkley Point site, on the Somerset coast in South-Western England,
    • two reactors at the Sizewell site in Suffolk County, in East of England.

  • Fourniture

    Etendue de la fourniture

    AREVA will be involved in all activities related to the UK EPR™ Nuclear Steam Supply System (NSSS) project:

    • Design and procurement,
    • Erection and commissioning,
    • Digital control system:
      • Safety Instrumentation and Control (I&C),
      • NSSS operational I&C engineering,
      • Simulator for safety I&C and core control I&C system.

    EDF Energy is responsible for the overall project management.

    EDF is the Architect Engineer.

    Civil Work and Turbine Island suppliers are selected by EDF.

  • Sous-traitance

    Logisitque d'approvisionnement AREVA

    British companies have been identified as potential suppliers being integrated in a globally qualified industrial supply chain and industrial partnerships have already been secured.
    An important Co-operation Agreement has been signed committing AREVA and Rolls Royce for future contracts.

    Main primary equipment work

    • Forgings: AREVA Creusot Forge, France and Japan Steel Works (JSW) in Muroran, Japan
    • Reactor Pressure Vessel, steam generators and pressurizer: AREVA Chalon Saint-Marcel, France
    • Reactor coolant pumps and control rod drive mechanisms: AREVA Jeumont Solutions For Pumps and Mechanisms (JSPM), France.

    AREVA project resources:

    At the current stage, several hundreds of engineers are already working on the project.

    Construction site employees:

    At the height of construction, 5,600 people will be mobilized and in the operational phase 900 employees will be needed at Hinkley Point.

  • Certification

    Certification

    The Health & Safety Executive's (HSE) Office for Nuclear Regulation (ONR) and Environment Agency (EA) have developed a two-phase licensing process:

    • Generic Design Assessment (Phase 1) and
    • Specific plant licensing/permitting (Phase 2).

    Phase 1

    After four years of the most detailed and careful examination of the EPR™ design by the UK regulators, phase 1 is now in the final phase of completion with the integration of post-Fukushima recommendations.

    In fact, AREVA and EDF submitted the EPR™ reactor design to UK authorities in July 2007.

    • ONR granted an interim Design Acceptance Confirmation (IDAC) and
    • EA an interim Statement of Design Acceptability (ISODA) in December 2011

    concluding that they are largely satisfied with both the design and the safety case of EPR™.

    Phase 2

    Phase 2 has started with project execution for Hinkley Point C under EDF Energy responsibility and in which AREVA as NSSS supplier and EDF as Architect Engineer have major roles. In July 2011, EDF Energy applied for the Nuclear Site License.

    Next step will be the submission of safety reports to ONR in 2014.

     

  • Etapes clés

    Les dates clés

    July 2011: Contract signed between EDF Energy and AREVA enabling AREVA to start manufacturing of the heavy forgings for the first of the two EPR™ reactors required for critical reactor components.

    EDF Energy received consent from local authorities in Somerset to start site preparation of Hinkley PointC.

    October 2011: EDF Energy applied for consent to construct and operate a new NPP at Hinkley Point from the UK’s Infrastructure Planning Commission.

    December 2011: Framework contract for NSSS and operational I&C and work order announced by EDF. This allows AREVA to start the first engineering designs related to the NSSS of the two Hinkley Point units.

    February 2012: Signature of a MOU between EDF Energy and AREVA where both companies agree on the commitment to finalise key NSSS contract for Hinkley Point C

    End 2012: Planned EDF final investment decision.
