Isotope exchange reaction on solid breeder materials

摘要

Lithium ceramic materials such as Li_2O, LiALO_2, Li_2ZrO_3, Li_2TIO_3 and Li_4SIO_4 are considered to be as candidate for the tritium breeding material in a deuterium-tritium (D-T) fusion reactor. In the recent blanket designs, helium gas with hydrogen or deuterium is planned to be used as the blanket purge gas to reduce tritium inventory and promote tritium release from the breeding material. In addition, the rate of isotope exchange reaction between hydrogen isotopes in the purge gas and tritium on the surface of the breeding material is necessary to analyze the tritium release behavior from the breeding materials.
