TOMOGLASS: Gamma Emission Tomography Applied to the Radiological Characterization of Glass Residues from the Cold Crucible Vitrification Process

The TOMOGLASS project aims to develop an innovative gamma tomography system, capable of operating in High-Activity environments, to perform 3D characterization of glass residues generated by the vitrification process of nuclear waste. The objective is to precisely locate platinum-group inclusions, which are poorly soluble in glass, in order to improve both the understanding and control of the process. The system is based on a compact gamma imager integrating high-resolution pixellated CZT detectors, collimated (pinhole-type), and mounted on a robotic arm. It will enable multi-isotope reconstruction using advanced tomographic algorithms. This project is part of the modernization of the La Hague facilities and the integration of digital technologies into the “factory of the future.
