UNED, partially under contractual activities of F4E, has developed GEOUNED: a software tool that converts engineering CAD models into Monte Carlo radiation transport models, with the ability to convert back to CAD. It is an open-source tool, accessible, easy-to-install, and uses Open CASCADE as the CAD engine and FreeCAD as the interface for python scripting. GEOUNED can handle decomposition and automatic void generation algorithms, and is capable of tackling various problems in geometry conversion. F4E is currently supporting its transformation from a research tool used by a small group to a widely adopted code used within the broader neutronics community.

Technology assets

• Open-source software, easy to install.
• Automatic void generation algorithm that saves time and reduces human error.
• Helpful for any field that requires radiation transport simulations.
