摘要

Tritium breeding ratio (TBR) is one of the important parameters in design of a Deuterium–Tritium (DT) driven hybrid reactor. Therefore, selection of tritium breeder materials to be used in the blanket is very crucial. In this study, tritium breeding potential of the solid breeders, namely,_2O, LiAlO_2, Li_4SiO_4, Li_2ZrO_3, Li_8ZrO_6{\hbox{Li}}_{2}{\hbox{O}}, {\hbox{LiAlO}}_{2}, {\hbox{Li}}_{4}{\hbox{SiO}}_{4}, {\hbox{Li}}_{2}{\hbox{ZrO}}_{3}, {\hbox{Li}}_{8}{\hbox{ZrO}}_{6} orLi₂TiO₃{\hbox{Li}}_{2}{\hbox{TiO}}_{3} in a (DT) fusion driven hybrid reactor fuelled withThO₂{\hbox{ThO}}_{2} orUO₂{\hbox{UO}}_{2} was investigated. For this purpose in addition to these solid breeders, different types of liquid breeders, namely natural lithium, Flibe, Flinabe andLi₂₀Sn₈₀{\hbox{Li}}_{20}{\hbox{Sn}}_{80} were used to examine the tritium breeding behavior of liquid–solid breeder couple combinations. Numerical calculations were carried out by using Scale 4.3. According to numerical results, the blanket withUO₂{\hbox{UO}}_{2} fuel using natural lithium as coolant andLi₂O{\hbox{Li}}_{2}{\hbox{O}} as solid breeder had the highest TBR value.
