(54) STEAM GENERATOR


(57) In a steam generator, an inlet that feeds water is provided to the bottom side of a hollow tank, on the other hand, an outlet that discharges a vapor-liquid two phase flow is provided on the top end of the tank. Inside the tank, a plurality of heaters is provided as a heating unit that produces a vapor-liquid two phase flow by heating water, and a cylindrical member that includes a number of through holes is provided at the upper end in the tank as a rectifying unit that homogenizes the vapor-liquid distribution in the vapor-liquid two phase flow. Accordingly, as a flow of the vapor-liquid two phase flow is homogenized, fluctuations in the flow are suppressed, so that highly-precise control of a discharge flow can be achieved.
