As part of the ambitious project to construct six EPR2 nuclear reactors in France, the NGE group, through its subsidiary Sade, has secured a major contract for the cooling system networks (SEC). This contract involves the study, manufacturing, and installation of buried PEhd pipes for the emergency raw water circuit, a crucial component of the reactors’ cooling system.
The Système d’Eau de Circulation (SEC), or Water Circulation System, plays a critical role in cooling sensitive systems and components of a nuclear plant. In this context, NGE and Sade are responsible for constructing the intake and discharge pipes in PEhd specifically for the future EPR2 reactors. This cooling circuit relies on transporting external cold water to the reactor before discharging it back into the cold source.
Preparatory work, including studies and planning, began this year. To ensure the reliability of the methods and meet safety objectives, a series of large-scale feasibility demonstrations will be conducted at the Penly site by the end of the year. These “workshops” replicate real-life construction conditions and test the procedures for welding, assembly, and other key techniques.
NGE, leveraging its expertise in nuclear safety, ensures that all interventions comply with ISO 19443 standards. This certification confirms the group’s proficiency in managing the specific safety challenges posed by nuclear installations.
Additionally, this project is aligned with NGE’s strategy for local integration. It will help promote local employment through recruitment and training programs developed in cooperation with local stakeholders to ensure the success of this key infrastructure project.
A Commitment to Nuclear Safety
Executing this contract highlights NGE’s commitment to nuclear safety. Adherence to ISO 19443 standards is essential for operations on sensitive infrastructure such as nuclear plants. Every phase, from site preparation to the commissioning of pipes, is governed by strict safety protocols designed to ensure maximum protection for operators and the environment.
Feasibility Demonstrations Prior to Work Commencement
The planned demonstrations at the Penly site, which will involve recreating a section of piping under real construction conditions, play a vital role in the project. They not only test materials and methods but also validate the procedures that will be implemented across all EPR2 reactor sites. These workshops are a testament to the rigor with which NGE approaches the construction of nuclear infrastructure.
Local and Economic Impact
Beyond its technical scope, this project will have significant economic and social implications for the region. NGE and Sade’s involvement in local recruitment and training is crucial to the success of the operation. It also strengthens the local economic fabric while meeting the nuclear sector’s demands for skilled labor.
