Steam generator heated with liquid metal

摘要: A compact liquid-metal heated vapor generator (21) in which the liquid metal is typically sodium and secondary fluid water. The water conducted through tubes (29) of serpentine configuration with turns (51-53) nested. are modular bundles (27) modules extend throughout interior pressure vessel (23). flows countercurrent to fluid, vessel, penetrating between intimate heat-exchange relationship tubes. sealed tube sheets (37), (39); upper sheet (39) above level lower under a stagnant or quiescent zone (41) sodium.
