The current thesis was made to describe the CAD model and its use for the Horizon-2020 ESFR-SMART project (European Sodium Fast Reactor Safety Measures Assessment and Research Tools), a sodium cooled fast reactor development. There are two main purposes for the CAD model, such as to create a conceptual design based on previous experiences, so that it is easy to visualize it for all the project members. Moreover, to produce a model which can provide crucial input information for further research such as for the use of TRACE thermal hydraulic code. To create this 3D CAD model, the software used was Autodesk Inventor, which is a product development 3D CAD software. After the model was finished, volume and surface information was extracted manually from Inventor for the use of TRACE. During the thesis project, important achievements were made. First, a CAD model was created presenting all the primary systems of the reactor, the secondary cooling system and the decay heat removal system. Following this, information was extracted for further analysis and used in TRACE. Overall, the project proved the importance of such a model in helping for further concept development and providing input information for computational research tools.
