Nuclear

ESI provides innovative methodologies and value-added services for Nuclear Component Engineering. Our scalable realistic modeling solutions are designed to enhance the engineering approach with virtual prototypes of the components.

Plant lifecycle

Numerical simulation is essential in nuclear power to guarantee the safety of installations. Numerical simulation helps select appropriate materials, fine tune high quality manufacturing processes and rigorous testing to verify the functioning of components and safety systems, as well as conformity with regulatory requirements.

• Design and Engineering : ESI provides a large analysis scope including Computational Fluid Dynamics (CFD), manufacturing process simulation, structural mechanical behavior and regulatory analysis.
• Maintenance Engineering: Through a close collaboration with AREVA, ESI continuously develops and extends its simulation software capabilities with brittle and ductile fracture, cyclic stress-strain curves, J domain integrals, local models, and fracture mechanics analysis procedures ensuring compliance with regulations and standards.
• Lifetime extension: ESI brings together material laws and tools for prediction of material properties evolution and advanced simulation capabilities to control degradation phenomena and evaluate the risks associated with material aging
• Decommissioning: ESI software analyses including soil structure interaction, reinforcement steel calculation and detailed behavior of specific equipment included in the building model.

Project Management

ESI’s engineering productivity solutions insures teams follow regulations and best practices with improved performance.

ESI’s decision support system insures that teams follow the plan with real-time visibility, automates simulation tasks within the plan, keeps analysis models synchronized and maintains the link from simulation to design.

Our approach is based on a proven methodology taking into account current practices, enhancing and automating processes.

Certification

ESI’s quality assurance program is established to meet the stringent needs of the nuclear sector:

• ISO 9001 certification
• 10CFR50,
• ASME-NQA1,
• Q-N-100 and Q-N-300 (for AREVA),
• SGAQ (for EDF)
• In Japan, Nihon ESI is a certified supplier to MHI.
