Tritium release from beryllium pebbles after high temperature irradiation up to 3000Â appm He in the HIDOBE-01 experiment

This work shows preliminary results of the out-of-pile tritium release analysis performed on different grades of irradiated beryllium pebbles (different in size). Relationships between irradiation temperature, tritium inventory and microstructural evolution have been observed by light microscopy and scanning electron microscopy.
