HIGH-PERFORMANCE SIMULATION & COMPUTING

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.
Moreover, CS administers and operates the CCRT (Centre de Calcul, Recherche et Technologie, or computing, research and technology center), plus provides assistance for computational coding and application environments. The CCRT meets the requirements of high-performance computing across the complete range of CEA's competency centers, as well as for the Safran group (SNECMA, Turbomeca and Techspace Aero) and other industrial and academic partners.

CS partners with CEA in the Ter@tec initiative, a European competency cluster for high-speed simulation and computing. CS is also lead contractor in the project, IOLS (Infrastructure et Outils Logiciels pour la Simulation, or infrastructure and software tools for digital simulation), at the heart of the System@tic competitiveness cluster. In addition, CS continues in its role as lead contractor in the project, EHPOC (Environnement Haute Performance pour l'Optimisation et la Conception, or high-performance environment for optimization and design), which is set to follow up on IOLS.

SAFETY & NUCLEAR RISK MANAGEMENT

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.
Moreover, the mastery of risk supposes total traceability of nuclear materials. The main nuclear materials made use of by industry are regulated by the European organization, Euratom. Its mission is to verify that no government makes illicit use of nuclear materials. In France, there are additional specific measures to protect nuclear materials against criminal acts and to ensure homeland safety by obliging operators to carry out checks and show total traceability for their nuclear materials.
Within this framework, CS builds platforms for managing the nuclear materials of the CEA and IRSN, thus contributing to total traceability and data continuity. These systems empower accounting for all movements and transformations, and knowing the record, depending on who the users are.
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.

INDUSTRIAL INFORMATION TECHNOLOGY

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).
Partnering with Gaz de France (the French natural gas company), CS developed a networking supervision tool, Carpathe, to help engineering firms and gas distributors design and operate gas distribution networks.
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.
The first project concerns the modernization of the installed base of specialized devices that simulate the major subassemblies of a PWR. EDF power plant operators use this equipment to learn how to control critical plant components (reactor operation, volumetric and chemical control circuit, turbo-power generator, et cetera). This project aims at replacing the entire installed base of simulators present across all the nuclear electric power production sites of EDF. This mainly involves the industrialization of the prototype, Mistral (Module d'Interface Spécialisable Temps Réel en Ligne, or adaptable interface module for real-time online configuration).
The second project covers simulator configuration so as to allow studies and safety analysis, spanning both normal and accident-critical operation of all EDF PWR plants, from CP0 level to the future EPR one. This chiefly requires integration work on EDF's new simulation environment, SEPTEN: SULTANE (Suite Logicielle pour les Transitoires Accidentels and Normaux en etudes, or software suite for accident-critical transitory and normal states under study). These projects require complete knowledge and understanding of nuclear power plant operation.

INNOVATION

C3X TOOL SET FOR INDUSTRIAL ACCIDENT MANAGEMENT AND PREVENTION
The computational chain, C3x (Calcul des Conséquences & Cartographie, or computation of consequences & mapping) is an analytical and display tool to study atmospheric dispersion and the consequences of industrial accidents (nuclear, chemical, et cetera).
It makes possible:
• cartographic display of geographic zones,
• queries concerning geographic information,
• display of results from meteorological calculations of dispersion and consequences,
• analysis and cross-analysis of geo-referenced digital data,
• display of environmental measurements.

Within the specific framework of crisis management, the system has been enhanced to:
• map regulatory boundaries and danger zones in support of risk prevention policies,
• define a set of emergency measures in the event of an incident,
• transfer understandable information in real time to allow everyone, including the highest authorities, to monitor crisis developments.
