The work presents study of helium and tritium interaction with irradiated S-200F beryllium grade. The goal of research is related to solving the problem of detritiation of stored beryllium material. Also it is aimed to explain the mechanisms of processes occurring during tritium interaction with beryl-lium which is planned to be used in the future fusion-type reactor (FTR). The study consists of following stages: thermodesorption xperiments on gas release from irradiated beryllium, calculation of helium and tritium generated in beryllium; processing and analysis of experimental data; determination of basic pa-rameters of tritium interaction with irradiated beryllium. These data is needed for estimation of high-temperature degassing procedure such as detritiation method in case of S-200F eryllium grade as well as for calculation of tritium distribution in beryllium materials.References
