Egis, Designer for the New Nuclear

Egis your partner for your nuclear projects

Egis has been involved for 70 years in the design (conceptual and detailed) of nuclear plants for EDF, as well as nuclear installations for the CEA (research facilities) and for ORANO (uranium enrichment and spent fuel recycling facilities).

Over the last decade, this expertise has been enhanced through our involvment into major projects paving the way for nuclear industrial renewal: research reactor on material ageing under irradiation Jules Horowitz, research reactor on fusion reaction ITER, latest generation of water-cooled reactors EPR, sodium-cooled fast breeder reactor ASTRID…

We offer to our clients support derived from unparralleled feedback and state-of-the-art methodologies and innovation in project design and evaluation. This is our goal to the new nuclear field.

Preliminary studies & site surveys

Egis supports nuclear energy clients in choosing the most appropriate site. In particular, we perform industrial risk analyses, paying due attention to the challenges of nuclear and environmental safety, and we deliver study reports and regulatory reviews. We also help to reduce project costs by carrying out preliminary logistics and design-related studies.

Architect Engineer

With our technical competence, our knowledge of nuclear energy projects and our use of appropriate management systems, Egis is able to provide comprehensive project supervision of all the constructions, infrastructures and utilities essential to a nuclear installation. Our service offering thus covers  design, procurement, contracting, construction management, acceptance tests, precommissioning
and start-up.

Assistant to owner

From feasibility studies to consolidation of investment, operators need support they can count on – with technical competence, in guaranteeing compliance with regulatory procedures, and making sure the project is completed on time and on budget. With its experience and in-depth knowledge of technical, administrative and legal matters, Egis is your reliable partner in the management of interfaces between multiple stakeholders involved in the project.

Civil Engineering studies for new build

In the field of civil engineering, we provide support from the conceptual design stage right through to detail design (including reinforcement drawings). We assist construction companies throughout the entire duration of the project by ensuring we play our full part in support work. Where international projects are concerned, we have developed real expertise, enabling us to involve local engineering companies effectively and efficiently.

Consultancy & expertise in Civil Engineering

Every year, our solid investment in R&D enables us to offer our clients best engineering practices – for calculations and simulations (non-linear transient analysis, fast dynamic analysis, coupled analysis, multiphysical analysis), 3D modelling of structural elements (3D reinforcement, prestressing tendons, etc.), as well as for construction technologies (damping solutions, steel-concrete structures , etc.). We publish scientific articles and contribute to the development of French and European regulations.

Reappraisal of existing installations

The experience we have gained during 70 years of designing nuclear installations has doubled over the last 20 years as a result of the expertise and unique skills we have acquired in upgrading existing installations during reappraisals and mandatory safety inspections. This competence includes the seismic reassessment of buildings using state-ofthe-art procedures (pushover analysis, non-linear temporal analysis, SMA, etc.) as well as acting as main contractor for the full range of upgrading and renovation work.

Technical expertise

Egis has thousands of specialists available – for every project stage and for work on the most complex objects . This wealth of technical expertise enables us to cover with our own resources a wide range of disciplines required by nuclear engineering projects : geology, geotechnology, underground structures and tunnels, networks, fluid and solid mechanics, air pollution, pollution of the natural environment, instrumentation for works and sites, electricity, industrial risk management, etc.
