The engineering of the next generation of nuclear power plants requires to take into account the whole plant lifecycle: engineering, building, operating, maintaining and decommissioning. Satisfying stronger and stronger safety regulations requires the ability to trace any engineering information during the whole life of the nuclear power plant: one hundred years. The french electricity company Électricité De France (EDF) just started a Plant Lifecycle Management (PLM) project in order to design new (or improve existing) models, methodologies and tools able to ensure that these requirements are fulfilled. Among all the information related to a power facility, 3D data aims, in this context, at providing not only the as-designed (CAD) but also the as-built representation of the geometry of the facility components (HVAC, cable trays, pipes, valves etc.) as well as their relative position. With this project, the strategic goal of EDF is to ensure to keep the control over 3D data along the whole power plant data lifecycle. The nuclear industry misses a suitable standardized and open 3D model intended to this purpose. In this paper, we introduce a macro-procedural model intended to represent nuclear power plant 3D data and we present the first architectural design decisions and experiments.
