Risk management is at the heart of our approach and our offer, with a range of dedicated products, solutions and services whether in terms of fire, flood, contamination, seismic or radiation risks.

Our R&D teams work to respond to your challenges with innovative technologies, from design to certification, on-site installation and follow-up.

Fire protection

protection incendieThe management of a possible accidental fire situation in a nuclear installation calls for a set of provisions, all of which are aimed at maintaining control of operations while protecting people and equipment. Our teams provide you with the keys to risk analysis and all the elements of a protection strategy that is adapted to the specific characteristics of the nuclear industrial environment, including a wide range of equipment designed, manufactured, tested and certified in our workshops.

From the design phase to operation or as part of a life extension project, our intervention on your installation includes…

  • Analyses and studies: safety analysis and compilation of safety files, regulatory compliance (checks, advices), identifying ignition sources, assessing containment and associated ventilation, defining fire zoning, recommending active and passive means of protection, etc.
  • Digital simulations: smoke propagation, temperature and pressure variations, obscuring, influence of ventilation rate, behaviour of structures under heat flow, etc.
  • R&D, design, manufacturing, fire tests, on-site implementation of products and systems certified in our workshops and accredited by the main approved laboratories.
  • Technical assistance: coordination, planning and supervision of the work, checking, installation and removal of safety and fire-fighting equipment, training courses, monitoring and verification of compliance with standards.
  • Update or modification of old facilities.
  • Monitoring, maintenance, evaluation and modernisation of installed equipment to ensure sectorisation for the long term.
Flood protection

The protection of buildings and installations against flooding, and liquid-tightness in general, have become major challenges for the safety of people and property. However, unlike extremely well-regulated fire protection, there is no general test standard for certifying the performance of sealing systems.

Flooding and its consequences for the environment pose a changing safety issue which varies with each nuclear site, its location and its operating conditions. Our teams identify and re-evaluate for you the specific parameters of the hazard on your installation, then equip it with protections adapted to its requirements to guarantee its liquid-tightness and integrity.

From the design phase to operation or as part of a life extension project, our intervention on your installation includes…

  • Safety studies and advice: safety analyses and the compilation of safety dossiers, advice and assistance with design and operation, expert assessments and audits of containment provisions.
  • Support in the re-evaluation of the hazard: studies and assessment of the installations, expertise on certifications and developments in requirements, seeking solutions adapted to the specific requirements of the site.
  • R&D, design, manufacturing, testing, on-site implementation of products and systems certified in our workshops and accredited by the main approved laboratories.
  • Technical assistance: coordination, planning and supervision of the work, training courses.
  • Refurbishment or modification of old installations.
  • Monitoring, maintenance, evaluation and modernisation of the installed equipment to guarantee liquid-tightness over time.
Radiation protection

Throughout the lifecycle of a nuclear site, reducing the exposure of workers and the public to the potentially dangerous effects of ionising radiation, protecting facilities from contamination and complying with legislation requires a set of highly skilled methods and equipment. Our teams deploy a very wide range of radiation-protection solutions for you: advice, checks, products, remote control tools, instrumentation, logistical assistance for interventions, radioactive clean-up, decontamination, waste management, and more.

From the design phase to operation, or as part of a unit outage, life extension or dismantling project, our work on your installation covers all aspects of your project…

  • Radiation-protection consulting: safety analyses and compilation of safety files, monitoring and management of prevention plans, training (on-site, online, customised), audit of containment and criticality provisions, calculations, dosimetric management and reductions, studies (sizing, development, Alara, optimisation, organisation, etc.), analyses ( feedback, traceability, intervention reports, etc.), dispersion/contamination/impact calculations, numerical modelling, monitoring and management of intervention documents, provision of the French) radiation protection specialists, etc.
  • Radiological measurements: studies, design, certification and supply of measuring, instrumentation, control and protection equipment, operation of measuring cells, maintenance and instrument calibration, etc./li>
  • Radiological controls: mapping, sealing, circulation systems, support on sites (advice, marking, alerts, etc.), verification, installation and removal of safety equipment, etc.
  • Control of restricted areas: compliance with conditions of access for personnel and equipment, entry/exit management, etc.
  • Safe transport of radioactive materials: safety files, studies, certification, etc.
  • Industrial and production logistics: sizing and implementation of containment chambers, biological protection, management of tooling and radiation-protection warehouses, etc.
  • Large-scale soil monitoring and other specialised radiological measurement services.
  • Soil decontamination and treatment, including the rapid assessment of large volumes of potentially contaminated materials.
  • Approved dosimetry services for internal and external dosimetry (outside France).
  • Radioactive clean-up: decontamination, study and implementation of processes, containment of areas, remote-operation intervention, decommissioning of areas, etc.
Seismic protection

The prevention of seismic risk in the nuclear industry requires increasingly large safety margins, which must be regularly re-evaluated with the updating of stress spectra, together with constantly evolving standards and regulations, rules and methods of calculation. Our teams advise you on seismic analysis and technical solutions, up to the definition of a comprehensive technical reinforcement strategy and the implementation of compliance work. Our solutions include recommendations for future installations as well as for existing installations.

From the design phase to operation or as part of a life extension project, our intervention on your installation includes…

  • Initial design study: studies of the original plans and design notes, identification of ultimate limits and potential margins, preliminary and final design studies, safety studies.
  • On-site monitoring: verifications of the as-built condition, measurements of the ageing of the structure.
  • Normative seismic impact analysis: determination of the dimensioning spectrum, material behaviour laws, load combinations and weightings.
  • Numerical seismic impact analysis: ground/structure interactions, modelling, modal/spectral analysis, stress and strain checks.
