It is necessary to generate tritium in a fusion reactor. Elucidation of the tritium release behavior of solid blankets, which are tritium growth materials, is essential for tritium recovery. In this study, Li2TiO3-Li4SiO4 with lead addition samples prepared at Wuhan University of Technology was irradiated with neutrons at the Kyoto University Research Reactor (KUR), and tritium release behavior was evaluated by temperature desorption (TDS) and liquid scintillation (LSC), and defective species were identified and their extinction behavior was evaluated by electron spin resonance (ESR). In the presentation, we will present how the tritium release behavior changed due to the change in the amount of lead added.
