Abstract

In-situ tritium release experiments have been performed on LiAlO_b2, Li₂O, Li₂ZrO₃ and Li₂SiO₃ in the High Flux Reactor (HFR) at Petten. The experimental programme, EXOTIC, fits in the European Fusion Technology Programme on Blanket Technology and is jointly carried out by SNL-Springfields, SCK/CEN - Mol and ECN - Petten in cooperation with JRC - Petten. The vented capsules are purged with helium-0.1 vol% H₂. The main parameters were material density (75-95% TD), temperature (400-650°C), ⁶Li content, and irradiation time. During the steady state irradiation of EXOTIC-3 some temperature transients were carried out. They caused an immediate and strong effect on the release of tritium. More or less time was needed to restore steady-state tritium release. Almost complete tritium release was observed for: LiAlO₂ at 440°C, Li₂SiO₃ at 550°C, Li₂O at 600°C and Li₂ZrO₃ at 650°C for material densities of 75-80% TD. For 95% TD Li₂SiO₃ the fractional tritium release was < 70% at 630°C.
