CS offers a universal service suite in high-performance simulation, including access to powerful computing resources and advanced scientific coding, aimed at optimizing studies in simulation/modeling, and intended to speed product design and development phases.

Through combining simulation of physical phenomena with the use of virtual reality systems, customers benefit from an added dimension in their analysis and interpretation of complex computational results. CS works with its industrial customers, bringing to their projects its unique expertise, which blends its understanding of their businesses, broad experience in simulation/modeling (developed mainly through the simulation of nuclear testing for CEA) and mastery of virtual-reality display technologies.

The renaissance of civil nuclear energy around the world raises questions of risk management and what policies are likely to ensure perfect safety. The ability to design systems, which enable safety analysis, is one of the greatest challenges of nuclear energy.
They allow on the one hand determining more precisely the chances of different kinds of accidents, and on the other hand, managing aging installations under optimal conditions. For over 20 years, CS has specialized in scientific studies and software development, which concerns the physics of Pressurized Water Reactors (PWR) and Fast Neutron Reactors (FNR), accompanying its customers in their preparation of safety reports.

When the decommissioning of nuclear power plants is involved, CS offers customers its expertise in virtual reality, simulation, configuration management, and mission planning and follow-up.

In command, control and supervision, for several years, CS has been working on SCADA (supervisory control and data acquisition). It provides solutions for hydroelectric production-process and control-command simulation for hydroelectric power plants on the Danube and its tributaries (24 systems installed) as well as for studies of regulation in a control-command architecture with regard to nuclear propulsion systems (Technicatome).

In the area of industrial simulators, EDF recently awarded CS a contract for two major projects, simulating nuclear electric power plants, in order to treat safety and performance problems during multiple plant operation.
