Technical Lead for Contract NM3131 and System Lead for SIR-SIT-ATD – EPR2
Under the PIAT 22-005 framework agreement titled “Engineering Services in the Field of Water Treatment”, EDF has appointed Artelia to act as the Technical Contract Lead for NM3131 and the System Lead for SIR-SIT-ATD on the EPR2 Project, which aims to construct six EPR2 units (two units on each of three separate sites).
- EDF CNEPE
- Penly, Bugey et Gravelines (France)
- 2024-2025
- Technical Lead
CONTEXT & ISSUES
Contract NM3131 covers the design, supply, and construction of elementary systems associated with chemical conditioning (SIR) and chemical monitoring (SIT).
- The SIR system ensures, through chemical reagent injection, the achievement and maintenance of the required physico-chemical parameters for the secondary circuit, auxiliary circuits, and steam generators (SGs) during wet lay-up shutdown conditions.
- The SIT system enables sampling and analysis of the chemical parameters in various fluid systems.
- The ATD-UTC system (Chemical Treatment Unit) handles the chemical purification of feedwater during startup phases.
Performed services
As the Technical Lead for Contract NM3131, Artelia is responsible for the following missions:
- Organising, planning, and initiating execution studies (updating study action plans).
- Leading, coordinating, and supervising all technical stakeholders.
- Supporting the project engineer and planner with schedule monitoring.
- Monitoring compliance with the planning schedule by EDF’s internal study contributors.
- Drafting technical documents under the responsibility of the contract’s technical lead.
As the System Lead for SIR-SIT-ATD, Artelia is responsible for:
- Ensuring control over system design, operation, performance, and history, in alignment with safety and regulatory requirements, EPR2 Project specifications, and operational performance targets.
- Identifying and cascading applicable requirements to systems, ensuring compliance.
- Integrating all technical aspects related to the systems: safety, operations, mechanical, I&C (Instrumentation & Control), instrumentation, electrical, and testing.
- Ensuring completeness and consistency of the system design documentation.
- Managing system design and operational changes, maintaining design principles and keeping system documentation up to date.
- Managing interfaces between the supervised systems and other systems within the facility.
- Performing basic design studies and part of the detailed design, in line with safety, quality, cost, and schedule objectives.
