Design of the FLIQURE experiment

A preliminary design is presented for the FLIQURE or Fusion LIQUid Release Experiment. This experimental system is designed to measure the mobilizatio n of tritium, fluorine, and other constituents in molten Flibe following tr ace neutron irradiation at fusion-relevant temperatures (500-1000 degreesC) . Trace neutron irradiation is achieved using a spontaneous fission Cf-252 source that produces a relatively uniform concentration of tritium in the F libe. The experimental goals aim to better understand the mechanisms, mobil ization rates, and physiochemical forms of tritium mobilized from the Flibe along with other potentially detectable radioactive isotopes and toxic-mat erial species under inert-gas, air, and steam-ingress conditions. System de sign details are discussed which include neutronic studies to optimize trit ium production, thermal design to maintain and isolate molten Flibe, and in strumentation to meet experimental goals.
