Context and challenges
The client, a leader in the nuclear sector, has an engineering centre which acts as the responsible designer for the EPR units under construction in England. Amongst its other duties, the engineering centre is responsible for specifying the standard, operational instrumentation and control for French and English EPRs.
The instrumentation and control comprises a group of programmable logic controllers (PLCs) and monitoring systems used to control and monitor the unit. It contributes to ensure safety and the smooth functioning of the installation.
One of the steps in the instrumentation and control design phase is the specification and creation of functional diagrams, with information communicated to the operators in control images.
As part of this work, the engineering centre of the client called on Assystem to produce the Detailed Functional Diagrams and the control images for the first configuration status.
The produced DFDs and control images concern 70 elementary systems (electrical, mechanical, HVAC) broken down into three batches.
