Risk monitoring and safety


To ensure the safe and reliable operation of industrial facilities, companies and public authorities must place safety at the heart of their strategies. In sectors such as nuclear power, defence or even public transport, managing risk and safety of equipment, systems, and personnel are crucial challenges.

Assystem offers more than 55 years’ experience in nuclear safety, industrial and environmental risk, and human factors.

Nuclear safety

Nuclear safety requirements place greater responsibility on nuclear operators and their supply chain. A safety culture that covers all of an installation’s safety risks must be incorporated as early as possible in all projects, right from the design stage.

Our unique positioning among major nuclear sector players, from the design stage through to dismantling, provides our project teams with a global vision of all of these challenges. The nuclear safety specialists at Assystem actively engage with other technical disciplines on a daily basis, enabling them to anticipate difficulties and share fundamental concepts to instil a robust safety culture.

Nuclear safety policy and nuclear risk control

Assystem operates a rigorous nuclear safety policy as well as its , which we report on annually as part of our Nuclear Risk Management Report

We share experience to improve the quality of our services, providing a dedicated nuclear safety business organisation, led by Assystem’s Head of Nuclear Risk Management. Our goal is to reduce the operating and regulatory risks nuclear operators are exposed to within the framework of our nuclear safety expertise.

These services are driven by Assystem’s entities alongside CRA (our UK subsidiary specialising in the management of risk, safety, and human factors).

Industrial and environmental risks

The safety of our customers’ installations and the ability to support the energy transition are our utmost priorities.  In the pursuit of alternative, sustainable solutions, we are supporting the evolution of new energy sectors (green hydrogen, conversion of LNG/CNG vehicles, etc.) to imagine the world of tomorrow. Control of industrial and environmental risks is a key challenge for the development of these new sectors.

We offer a broad range of services to prevent industrial risks and hazards, all of which require danger reports, impact studies, regulatory files and compliance reporting, zoning, as well as more specific analyses: modelling dangerous phenomena, lightning risk, technical lightning reports, etc.

Human factors

Human factors are responsible for around 90% of accidents in nuclear power and other highly complex industries.  Recognising and accounting for these factors at the design stage enables improvements in reliability and efficiency of human intervention and ensures the safety of personnel.

Our expert teams, including our dedicated subsidiary, CRA, take responsibility for reviewing risks linked to human factors to:

  • The role of personnel in the operation and maintenance of future installations and all related risks
  • Anticipate and develop a plan to integrate organisational and human factors
  • Create conditions, from the design stage, which improve the operational and organisational safety/security culture

These regulatory studies are imposed by nuclear safety authorities and are incorporated in the nuclear safety report of the installation.

Our human factors and reliability assessment offer includes services such as:

  • Support for human factors
  • Human Factor Integration Plan (HFIP)
  • Quantification of human error
  • Justification of human error

Our digital expertise provides us with solutions such as virtual reality (VR), used in project management activities to enhance our reports and safety/human factor demonstrations.
