Siting, licensing and environmental services


During the initial phases of an industrial project, our customers are faced with challenges such as assessing potential project sites, obtaining dimensional data for design purposes, and conducting impact reports. Beyond nuclear, these challenges are equally crucial for other sectors: building and construction, infrastructures, renewable energy, transport, etc.

Our teams provide a comprehensive offer which combines expertise with innovation to deliver: site testing and environmental and social impact assessments (ESIA), licensing and permitting support, and environmental monitoring and compliance.

Site tests and impact studies

Geoscientific competencies and flexibility for lower costs and shorter project timeframes

Seismic activity, weather conditions and other climate-related issues represent risks to costs, schedules and the safety and security of projects.

Our international teams adapt to local requirements, enabling siting activities for complex projects irrespective of size. Our comprehensive offer makes us a unique provider.

  • Geological surveys
  • Geophysical surveys
  • Geotechnical studies
  • Topographical surveys
  • Hydrological surveys
  • Hydrogeological surveys
  • Seismological & seismotectonic surveys
  • Marine surveys
  • Meteorological / Areological surveys

Expertise in environmental and social impact assessments to help you make responsible choices for local ecosystems and populations

During project commissioning phases, we perform environmental, social and health impact assessments relative to our clients’ needs. These assessments review the economic and social requirements as well as the impact on the environment and the social and health impact resulting from the project.

Environmental support services

  • Environmental baseline studies (noise & vibration, waste, agriculture and soils, air quality, arboriculture, archaeology, carbon reporting, contaminated land, heritage, landscape, water quality / resources)
  • Terrestrial & Marine ecological surveys​
  • Sustainability studies / Ecology services (incl. BREEAM, CEEQUAL)
  • Environmental management & training​

When completed, these assessments provide our customer with an environmental and social impact assessment report.

Combining experience and technological innovations in modelling and geographic information systems (GIS)

We deliver services including collection of geographic information for a wide range of international projects by combining the latest technologies with decades of experience:

  • Urban information system
  • Urban energy distribution
  • Visual impact analysis
  • Topographical mapping
  • Marine survey studies 
  • Recreational project applications
  • Alignment sheets
  • Special crossing drawings
  • Land acquisition maps

Licensing and authorisations

Recognised expertise in successfully supporting licensing and building permit processes

Building a new nuclear installation requires rigorous assessment and approval by the Nuclear Safety Authority of the host country throughout the installation lifecycle (assessing the choice of location, construction, operation, final shutdown, dismantling, and any modifications).

With more than 50 years’ experience in supporting new or existing nuclear programmes, Assystem supports its customers at every stage of the approval process, from the initial request through to the final shutdown and dismantling of the installation.

To meet safety requirements and boost confidence in the project, we provide expertise in:

  • Drafting and submitting documents required for permits and to validate projects
  • Coordinating project stakeholders to secure and impact authorisations
  • Integrating all requirements into a digital database, optimising the process of obtaining permits thanks to digital modelling

We work with national regulators, governments, operators, reactor manufacturers or suppliers to coordinate our stakeholders’ collaborative efforts.

The Assystem teams harness the power of digital tools and technologies to optimise the licensing process:

  • Using sophisticated digital databases to cover all international standards and stakeholder consultation diagrams and,
  • Extracting, comparing, standardising and allocating requirements to these models.

These features are developed by integrating automatic learning techniques thanks to model-based system engineering (MBSE).

Commitment and compliance with International Atomic Energy Agency (IAEA) approaches

We address all possible requirements for siting and design in the nuclear sector:

  • Requirements management /breakdown of product structure
  • Interface management
  • Licensing strategy and coordination with regulators
  • Preliminary safety report and progress review

Customer support and project progress optimisation

Assystem’s licensing support enables customers to:

  • Ensure smooth and seamless monitoring of the permit validation process,
  • Guarantee project compliance with sector and country standards,
  • Champion reliability in terms of risk management and safety

Monitoring and environmental compliance

In response to increasingly stringent regulatory requirements, environmental concerns have become more complex, particularly in construction. We help our customers manage the environmental risks to their projects, identifying and implementing sustainable solutions.


  • EIA/ESIA/ESHIA Monitoring​
  • Reinstatement Monitoring​
  • Environmental Auditing


  • Construction Environmental Project Management (CEPM)​
  • Environmental compliance with International Finance Institutions   (permitting, construction environmental planning, legal compliance, risk management, surveys, monitoring, consents, reports, operational control and auditing
