CONTEXT AND CHALLENGES

The client is a start-up, which aims to develop a low-power, molten-salt Generation IV reactor, the XAMR® (eXtra-small Advanced Modular Reactor). This can be deployed as close as possible to consumers of electrical energy and/or heat, both in France and abroad.​

In this context, the client has commissioned Assystem to produce a digital twin, deploy systems engineering methods, produce studies for the prototype reactor's reception facility and support the safety teams in producing studies and defining the safety approach.​

Project Scope

PLM deployment of the 3D EXPERIENCE​

  • Administration of the 3DX platform to support reactor design studies
  • Exploration and configuration of applications to meet business needs

Supervision of systems engineering methods​

  • Advising and supporting the choice of systems engineering methods to be implemented on the programme​
  • Monitoring the work, providing local support for systems engineers and checking compliance with the chosen methods

Reinforcing safety ​

  • Providing expertise to the Safety and Security Department to prepare for meetings with the Nuclear Safety Authority​
  • A team integrated into the project management's safety team to carry out preliminary risk and aggression analyses, and to manage and support systems for FMEAs*.

Carrying out studies for the test centre​

  • Production of a sketch of the building to house the prototype reactor​
  • Proposal for the preliminary design of the prototype reactor building​
  • Preliminary design studies: ventilation (nuclear), ILVS(S)/HVS**, fluids, mechanics and processes)​

Reinforcing ISS*** and PMO**** capabilities

*FMEA: Failure Mode and Effects Analysis​
**ILVS(S)/HVS :  Industrial Low-Voltage Systems (Security) / High-Voltage Systems ​
***ISS: Information Systems Security ​

****PMO: Project Management Office​

Results

  • Centralised product design with the deployment of a digital twin, providing descriptive modelling capabilities (functional, 3D), traceability between project data and simulation ​
  • Strengthened customer teams with expertise in the nuclear sector (design, safety) and systems engineering​
  • Optimised design times and more reliable studies due to the deployment of systems engineering methods​
