Sn-Li, a new coolant/breeding material for fusion applications.
A new breeding material, Sn-Li has been proposed for the APEX and ALPS programs. The key reason for proposing this material is that it has very low vapor pressure. Since both APEX and ALPS are investigating free surface flow for the blanket and divertor, respectively, low vapor pressure is a big advantage. This paper summarizes the results from a preliminary investigation. The early conclusion is that Sn-Li can be used as the coolant/breeding material for the APEX and ALPS applications. It has several attractive features, such as low vapor pressure and high thermal conductivity, but it also has some potential issues, such as material compatibility and activation. Further investigation will be required to assess the potential advantages of this material compared to other breeding materials.
