Following the permanent shutdown of two reactors at a French nuclear power plant, the dismantling operations will start in 2025 at the earliest, after the removal of the spent nuclear fuel.
Decommissioning projects are managed by a dedicated entity of a major nuclear player. It works on decommissioning and radioactive waste management. Part of the decommissioning activities (particularly the construction sites) are entrusted to specialised service providers, under the responsibility of this major nuclear player. All decommissioning operations, as well as operations, are under the permanent and independent control of the French Nuclear Safety Authority (ASN).
In this context, Assystem was appointed to produce the Building Information Modeling (BIM) model by using 3D point clouds for the reactor. The service is fully in line with the Dismantling Information Model (DIM) project of this client in charge of dismantling projects which implements all the methods and interconnected tools in order to optimise its operation.
The mission consists of producing the BIM model of reactor in 9 months, which is part of a DIM approach that covers a data-centric approach integrating editing tools (SolidWorks and REVIT), data storage/sharing/import/export functions and visualization tools (including MySurvey, Navisworks and the 3DExperience from Dassault Systèmes).
The mission required the mobilisation of the following skills and expertise:
Thanks to the BIM model of the reactor, the client will be able to:
The client will thus be able to:
