Water and hydrogen in heavy liquid metal coolant technology

Lead and lead-bismuth are currently considered as coolants in some reactor and accelerator driven system designs. Processes related to water steam and hydrogen supply to the primary circuit are very important for the coolant technology. The similar physical and chemical processes occur, for instance, in case of steam leaks to the coolant caused by failure of steam generator (SG). In this paper are designs of heat and mass exchangers, in which water or other liquid and gaseous media are in direct contact with heated lead-containing coolant. These heat and mass exchangers can be used for evaporation of liquids, as well as for hydrogen production technologies.
