In early 2023, CORYS delivered the EPR2’s basic design simulator to Edvance. The project enabled new model production methods to be validated, as well as building up experience about the future reactor and facilitating the growing headcount of the Nuclear business line, which is due to double by 2030.
The basic design simulator delivered in early 2023 describes some twenty systems, mainly the nuclear island, with simulation depth limited by the available engineering data at this stage. Its purpose at Edvance is to de-risk the functional specifications by simulating five transitory states spanning normal operations, incidents and accidents.
New: process simulation in agile mode
The first stage provided a constructive learning experience when it came to methods.

For each batch, discussions examined the degree of maturity of available data to determine the new simulation scope that could be envisaged. The process is now tried and tested and universally acclaimed; it could be reproduced to develop the detailed design simulator.
Christian Leo, who heads up the Industry and Energy BU explains:
The same tool for CAD and simulation
The tools involved include NFD, CORYS’ software for the production of functional specification diagrams for I&C. Edvance has been using it since 2017 for the purposes of basic design; the plan now is to use it for the detailed design phase as well.
CORYS can also provide Sim FD, currently being evaluated by Framatome, for the design of the safety I&C. The first version is due to be completed by 2024, before the potential integration of Sim FD in the industrial engineering chain.
NFD and Sim FD are based on CORYS’ Alices® simulation platform. Its particularity is that it combines the functions of traditional CAD such as namespace verification, the ability to export high-resolution PDF documents, and simulation functions: these drawings can be executed in a single click, allowing dynamic verification of their conformity.
12 recruitments in 2022 and as many again in 2023
The basic design simulator project was also useful for another of CORYS’ priorities: speeding up new hires in the wake of the French government’s announcement of its intention to build at least 6 EPR2 reactors.
Christian Leo, says:
Faced with industrial giants that are also hiring massively, CORYS has a significant asset: it develops simulators, an ideal tool for quick and effective training of new arrivals in the nuclear industry and more especially EPRs, allowing onboarders to take on an active and highly motivating role.
