摘要： PROBLEM TO BE SOLVED: To provide a steam generator improving the thermal efficiency of a nuclear reactor by decreasing the pressure loss of a primary fluid.SOLUTION: The steam generator 10 includes: an external tube 15 that inputs a secondary fluid from a water supply nozzle internally and outputs water vapor from a steam nozzle; a heat transfer tube 17 that causes the primary fluid 5 to flow inside the external tube 15 to make the secondary fluid water vapor by heat exchange; a supply nozzle 26 that supplies the primary fluid 5 to an inlet chamber 31 formed in the external tube 15 to communicate to an end of the heat transfer tube 17; and a guide passage 20 that guides the primary fluid 5 from a connection 24 of the supply nozzle 26 connected with the external tube 15 toward the direction of an end of the heat transfer tube 17.
