Sn-Li alloy is considered as a potential liquid breeding materials for fusion reactor. For an effective design of the experimental loop for liquid breeder in-pile production tritium and liquid blanket neutronic

in this paper

a mathematical model of gas-eutectic interface and a time-dependent multi-group diffusion equation and eigenfunction expansion method has been introduced and the tritium breeding behavior of liquid Li25Sn75 alloy has been imitated. Calculation results have shown that cross section of Sn-nat (n

2n) is 1.5 barns at 14 MeV

and the tritium breeding with time in 7Li and 6Li is showing no difference with LiPb alloy and Li2O

and the effects on TBR from Li25Sn75 alloy is sensitive and TBR increases with increasing sizes and concentration of 6Li.
