Abstract

A direct-pass steam generator capable of operating at variable load conditions and achieving an indirect heat exchange between liquid sodium and feedwater, comprising: means defining a main flow path including steam generation pipes; means for maintaining said steam generating tubes in contact with said liquid sodium; means for supplying feed water to said main flow path such that through said main flow path a mixture of steam and water is passed in two phases; steam separator means in flow communication with said main flow path to receive said two phase mixture and separate the vapor from the water; regulating valve means operatively connected between said means for supplying feed water and said main flow path and responding to the flow of feed water in said main flow path, such that said regulating valve means is moved from a position open to a closed position in correspondence with a decrease in flow of said feed water; and check valve circuit means operatively connected in flow communication between said steam separator means and said regulating valve means such that said water from said vapor separation means is passed to said steam generating pipes whereby a flow by natural circulation is established in said main flow path.
