| 内容記述 | To investigate tritium release behavior from ceramic breeder blanket, tritium release experiments are ongoing at Fusion Neutron Source (FNS) Facility of JAEA. Tritium generated in the Li$_2$TiO$_3$ pebble bed by DT neutron irradiation is purged out by passing through helium. Chemical forms of tritium released are water form (HTO) and hydrogen form (HT). Tritium is collected for each chemical form by gas washing bottles and oxidation reactor. In this work, chemical form of tritium recovered was investigated with various contents of the purge gas such as (1) dry He, (2) wet He, (3) wet H$_2$ (1¥%)/He and (4) dry H$_2$(1¥%)/He. It was clearly shown that addition of H$_2$ and/or H$_2$O is necessary to enhance the tritium release. Furthermore, in cases of (1) and (2), release of tritium in hydrogen form was observed. This suggests there is release path via formation of gaseous tritium, and one of the clues to clarify tritium release mechanism has been obtained. | |||||
