Abstract Scope |
Florine molten salts such as FLiBe and FLiNaBe are promising liquid blanket materials for fusion reactors. The understanding of tritium behavior generated by the nuclear reaction of Li with neutron is important from a viewpoint of safety. The information of tritium behavior in the florine molten salts is also useful for molten salt fission reactors. In this study, we observed the release behavior of tritium generated inside FLiNaBe by neutron irradiation at Kyoto University Research Reactor. The solid-state samples of FLiNaBe was irradiated by thermal neutrons with the total fluence of 1.7×10^15cm-2. After neutron-irradiation, the samples were put into a Mo crucible installed in a stainless steel tube and heated to 700°C in Ar gas flow. The release ratio of each chemical form was approximately TF:HT:HTO=15:65:20. Initially, the most of tritium was released as HT but eventually, the release rate of TF was increased after long time heating. |
