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.
