ICONE23-1334 CFD SIMULATION OF WATER EVAPORATION IN COLD TRAP COOLER FOR COOLING EUTECTIC PB-LI17

Abstract

Cold trap is a device for removal of corrosion products from liquid metal (Pb, Pb-Li17). Separations of these impurities occurs at lower temperatures than the operating condition. The goal of the cold trap is to efficiently cool the eutectic and one of the possible coolants is boiling water. Steam-water mixture created above the cooling part subsequently condenses at fins of tertiary cooling circuit with cold water. The created condensate will flow back and natural circulation will be provided. The main goal of this work is study of use of water boiling model provided and implemented in ANSYS FLUENT R15 program for the cooling purposes of the cold trap secondary circuit. Results will be used in the future for validating on the actual equipment, which is currently under development.
