As part of the EPR2 program launched by EDF, SOCOTEC is involved — as part of a consortium — on the three identified sites: Penly, Gravelines and Bugey, and potentially on new projects that may be launched in Europe whose start occurs before the end of the contract. 
Our experts place their know-how at the service of the quality and safety of infrastructures, from the design phases through to the execution of works. 

Key Information 

  • Date: 2024  
  • Client: EDF  
  • Size: 6 new EPR reactors  
  • Locations: Penly (Seine-Maritime); Gravelines (Nord); Bugey (Ain)  

Project details 

The program EPR2 (European Pressurized Reactor 2) is a French project for the revival of civil nuclear power, launched by EDF to respond to energy challenges of sovereignty and security of supply. It plans the construction of six next-generation reactors on three identified sites in France: Penly, Gravelines and Bugey.  

Description of the tasks entrusted 

The experts from SOCOTEC had already taken part in the first EPR project of Flamanville, supporting the securing of various civil-engineering aspects. For these new projects, SOCOTEC is part of a consortium responsible for assisting project management by controlling and validating technical characteristics, during the study phase and throughout the completion of works.

SOCOTEC Expertise

SOCOTEC’s technical assistance adapts to the specificities of each site. As an example, here are the missions carried out at the Penly site (the most advanced of the three):  

  • Draftsman-designer tasks: graphical monitoring of execution studies, verification and integration of as-built plans, updating VRD synthesis plans.  

  • Maintenance of existing buried networks and upkeep of roadways.  

  • Creation of site infrastructures: 

    • Small-scale earthworks, 
    • Laying of piping (rainwater, wastewater, pressurized networks), 
    • Backfilling works, 
    • Preparation of platforms for site installations.  
  • Major earthworks and main civil engineering: 

    • Demolition of existing structures,

    • Large-scale earthworks,

    • Special foundations: slurry walls, injections, diaphragm walls, 

    • Marine-extension works: modification of a dike, installation of grooved concrete blocks, extension of the platform.  

  • Implementation of tertiary and industrial projects: temporary and permanent buildings, temporary installations, parking areas.
