Assystem and Dassault Systèmes Partner to Accelerate the Development of Advanced Modular Reactors

• Experts in nuclear engineering projects and virtual twin technologies aim to drive the use of virtual twins in next-generation nuclear technology programs
• Combining Dassault Systèmes' 3DEXPERIENCE platform and Assystem's system engineering and project management services and support will help customers ensure program development
• Innovators gain access to a technology and methodology ecosystem that supports the sector's development

Dassault Systèmes (Euronext Paris: FR0014003TT8, DSY.PA) and Assystem, an international engineering, digital services and project management company, today announced their partnership to accelerate the development of advanced modular nuclear reactors that can produce efficient, safe and reliable energy.

The two companies are combining their respective expertise in virtual twin technologies and nuclear engineering to drive the use of virtual twins by customers seeking to manage the complexity of their advanced modular reactor programs and address challenges across all program phases.

Dassault Systèmes and Assystem will implement Dassault Systèmes' 3DEXPERIENCE platform and Assystem's system engineering and project management services and support for customers. This will establish one collaborative virtual ecosystem in which a customer's specific processes and methodologies are organized to ensure the data quality and traceability needed for the efficient design and delivery of an asset.

"The complementarity between Assystem and Dassault Systèmes makes sense for the nuclear sector. Advanced modular reactor developers are introducing new concepts that can drive low-carbon energy efforts. Through our knowledge of nuclear projects, system engineering and software development, we can provide them with the infrastructure, services and support to scale their production and transform the sector," said Christian Jeanneau, Executive Vice President, Digital International, Assystem.

"Our 3DEXPERIENCE platform has proven its versatility in responding to the unique needs of 12 industries served by Dassault Systèmes. Extending our long-standing partnership with Assystem to this strategic initiative will help innovators in the nuclear sector integrate best practices from other industries, industrialize their reactors, and rapidly introduce a new generation of advanced nuclear technologies," said Florence Verzelen, Executive Vice President, Industry, Marketing Sustainability, Dassault Systèmes.
