new Grand Paris Express transport network), (iii) CEA (in the areas of defence, decommissioning and waste processing), and (iv) the ITER project based in Cadarache, France.

Assystem now operates in the engineering market through two divisions:

● Energy & Infrastructure (86.4% of 2017 revenue);

● Staffing (11.4% of 2017 revenue).

Assystem is still closely associated with the growth of its former GPS division as a result of its ownership interest in Assystem Technologies (39.20% at 31 December 2017 and 38.16% since 31 January 2018). This investment is accounted for by the equity method in Assystem’s consolidated financial statements. ENERGY & INFRASTRUCTURE Assystem's Energy & Infrastructure (E&I) division works with nuclear utilities companies and contractors, players in the conventional and renewable energy sectors, designers and operators of transport infrastructure and other complex infrastructure, and life sciences companies, providing them with the expertise it has built up through its long experience in the nuclear industry and infrastructure engineering in environments with complex operating conditions and/or stringent safety requirements. E&I operates in France and internationally in the Nuclear, Energy, and Infrastructure (collective and industrial) markets and its clients are generally large prime contractors. It specialises in research instruments, electricity production plants and the fuel cycle, urban and regional transport systems, site decommissioning and waste processing. It is a well-established player in both infrastructure transformation (new methods of producing and storing electrical energy) and digital transformation (project development and providing secure solutions for users). E&I's engineering operations are structured around technical and project departments and its business areas include project management consultancy, engineering procurement and construction management, design engineering, and systems integration. Project Management Consultancy (PMC) E&I's PMC teams use project management methods put in place by Assystem based on an international PMC model that is suitable for complex installations. PMC services generally include assistance with the construction and start-up phases as well as for commissioning tests, with the design and performance of safety tests forming a particularly important aspect. Assystem's main PMC projects are currently being carried out for (i) EDF (assistance for power plant activities such as on-line maintenance and outages, as well as for the construction of the EPR at Flamanville, France), (ii) Société du Grand Paris (concerning the creation of the 1.2.1

Engineering Procurement and Construction management (EPCm)

Assystem provides EPCm services across all project phases, from design through to decommissioning. Our expertise in this area covers new projects as well as decommissioning and waste recovery and processing programmes. The main EPCm projects we are currently working on concern (i) buildings and electrical easements for ITER, (ii) the automation of lines and the renewal of trains for the underground rail network in Marseille, (iii) ancillary buildings for EPRs in the UK, and (iv) the nuclear portion of the CIGEO radioactive waste storage project. Design engineering This business area covers design, assistance with configuration management, logistical support, customisation and research into the related risks. In the nuclear sector, the focus of our design engineering work is on demonstrating how operators can meet their safety objectives, which we do by analysing risks and verifying the resistance of systems based on scenarios of attacks and internal failures. For its operations and design support services, Assystem has in-depth multi-sector expertise and its wealth of experience includes signalling designs for SNCF Réseau, mechanical and fluids systems designs, Balance of Plant analyses for the energy sector, detailed designs for the conventional turbine islands of EDF's nuclear power plants, designs of elementary and command/control systems, and materials classification analyses. Systems integration Systems integration services are used for complex projects, for which Assystem draws on its expertise in automation and the construction of buildings intended for complex processes. These services not only cover the installation phase but continue right through to the commissioning tests for the processes themselves. They are provided in a wide range of fields and our experience in this area includes projects related to the cybersecurity of an energy transmission network, the energy efficiency of the Paris High Court and the command and control systems for nuclear power plants.
