Tritium transport behavior in the molten lithium–tin alloy Original Research Article

Using the in-reactor tritium release experiments, the tritium transport behavior in the Li20Sn80 alloy was studied, including the tritium diffusion in the alloy and the mass-transfer at the interface between the alloy and the gas phase. The tritium diffusion coefficient is 1.27×10−9 m2/s at 873 K. The mass-transfer coefficient obeys the following temperature dependence: View the MathML sourceKD=2.82×10−4exp(−27.2(kJ/mol)/RT)(m/s)(673–873K) Turn MathJax on
