Assystem is an international company with one mission: accelerate the energy transition around the world.

Every day, our 6,500 switchers located in 12 countries (Europe, Middle East, Pacific Asia & Africa) connect their six thousand billion neurons to tackle the task of the century: switching to low-carbon energy.

We are a collective committed to the actors who are making the energy switch. Sharing our knowledge, expertise and values allows us to innovate and think differently about the energy transition.

Drawing on more than 55 years’ experience in highly regulated sectors subject to strict security and safety requirements, we provide our customers with engineering and project management services, as well as digital services and solutions to optimize the performance of complex infrastructure projects throughout their life cycle. The Group is currently ranked second in the world for nuclear engineering.

To ensure a viable, efficient, and reliable energy future for all.

Activities to be carried out as part of the service:

• System design and system integration into overall HPC design;

o Produce, review and update the system documentation for the mechanical and thermos-hydraulic design electrical, operator instructions, human machine interface, safety and environmental, control logic design as well as periodic testing in compliance with the engineering rules, methodologies, quality processes and tools.

o Particularly for instrumentation and control, performing the analysis for defining the I&C functional requirements of the system and production of the I&C logic: Writing of the Instrumentation & Control Functional Requirements Writing of Detailed Functional Diagram (DFD) Writing of FTP (Functional Test Platform procedure) specifications Analysis of the FTP results Writing of P5 text (I&C logic description) Writing of P6.x (alarm sheets, operating images and operating modes)

o Particularly for mechanical design Sizing of components e.g pumps, fans, pipework, pressure relief valves, tanks Perform thermal-hydraulic calculation and modelling with in house or commercial tools Ensuring the 3D model is consistent with the intended system design Formulate equipment specification and provide the data in Support to procurement team in formulation of technical specification for contract documentation Support to procurement team in technical surveillance of supplier documentation

o Analysis and verification of input data, requirements and lesson learnt from other stations

o Engage proactively with all stakeholders around the system in to ensure the delivery of a product meeting the requirements set by all disciplines (layout, civil, hazard, nuclear

o Contribute to topics around good practices, innovation, improvement of processes, and quality

o Participate in experience sharing activities within the discipline - Management of modifications related to the system, including:

o Managing requests for modification to system(s) issued by various external parties by producing specifications and following engineering cycle (I&C and/or mechanical design changes specifications)
