Flowable　behavior　of　lithium-based　liquid　tritium　breeder　was　simulated　through　the　liquid　GaInSn　alloy.　The　liquid　metal　GaInSn　and　quenching　oil　combine　together　to　simulate　the　liquid　dispersion　insulation　phase,　thus　forming　the　flowable　tritium　breeder.　A　flowable　metal　with　low　conductivity　characteristics　was　prepared.　The　liquid　metal　GaInSn　alloy　and　liquid　dispersed　insulation　phase　quenching　oil　were　mixed　to　form　a　new　fluid.　The　influence　of　magnetic　flux,　mixing　ratio,　and　temperature　on　the　viscosity　of　new　fluid　was　studied,　and　the　conductivity　change　of　fluid　with　the　addition　of　dispersed　insulation　phase　quenching　oil　was　tested.　Results　show　that　when　the　magnetic　induction　intensity　exceeds　a　certain　value,　the　viscosity　of　the　fully　liquid　metal　is　significantly　higher　than　that　of　the　composite　material　with　quenching　oil,　indicating　that　the　addition　of　quenching　oil　can　effectively　reduce　the　MHD　effect,　and　the　composite　material　with　quenching　oil　has　lower　flow　resistance　under　a　strong　magnetic　field.　The　conductivity　is　approximately　exponentially　decreased　with　increasing　the　addition　of　quenching　oil.　The　conductivity　of　the　flowable　tritium　breeder　increases　abruptly　after　standing　for　a　period　of　time,　and　then　stabilizes　again　at　the　new　conductivity　level.　If　the　breeder　is　re-mixed　ultrasonically,　the　conductivity　will　reduce　to　its　original　level,　suggesting　that　this　material　can　be　recycled　in　practical　applications.　©　2023　Rare　Metals　Materials　and　Engineering　Press.　All　rights　reserved.
