    • A thermo-siphon type generator apparatus making use of a gravity-type heat pipe in which a working medium is cyclically evaporated and condensed. The apparatus has a closed vessel filled with the working fluid and defining a lower evaporating section, an upper condensing section and a heat-insulated section between the evaporating and condensing sections. A turbine connected to a generator is mounted in or on the closed vessel. A first passage is provided for introducing the vapor of the working fluid generated in the evaporating section to the turbine, while a second passage is adapted for introducing the vapor from the turbine to the condensing section. The evaporating section includes a reservoir chamber adapted to store the working fluid in liquid phase, and a vapor bubble pumping space communicated with the reservoir chamber and adapted to generate, when heated, upward movement of vapor bubbles of the working fluid thereby to forward the vapor of the working medium to the turbine through the first passage. A third passage is provided for returning the condensate liquid to the reservoir chamber.

    • PROBLEM TO BE SOLVED: To provide moisture separating equipment improved in efficiency in separating moisture from vapor. SOLUTION: The condensation water from a heating-side outlet of a first-stage heat exchanger 2a is sprayed into the vapor flowing in piping 4 from spray nozzles 26a, 26b, 26c of a spray device. A temperature of the sprayed liquid droplets is higher than that of the fluid in the piping 4, the liquid droplets after spraying are joined with liquid droplets in the vapor to be a liquid film 8, and collided with an inner wall face of T-shaped piping 25 to be a liquid film, and they respectively flow into a drain pocket 5 to be captured. The liquid droplets in the vapor are joined with the sprayed liquid droplets to be grown into large liquid droplets, which is easily captured by a moisture separator, and then enter the moisture separator 1, thus the liquid droplets in the vapor is efficiently captured by the moisture separator 1, and the vapor of which moisture content is lowered, is heated by the first-stage heat exchanger and a second-stage heat exchanger to be utilized as the vapor for driving a turbine.

    • PROBLEM TO BE SOLVED: To suppress pressure vibration accompanying acoustic resonance occurring in a main steam system of a boiling water reactor.
      SOLUTION: Pressure sensors 13 and 14 are disposed in a steam dome 6 and a steam pipe 9, and pressure vibration amplitude is detected. The steam dome 6 or steam pipe 9 is provided with a Helmholtz resonance tube 12, and an opening regulating valve 11 is mounted to an inlet pipe 121. The opening of the opening regulating valve 11 is regulated in the direction of decreasing the detected pressure vibration amplitude. Thus, when the detected pressure vibration amplitude becomes minimum, the resonance frequency of the Helmholtz resonance tube 12 matches with (is close to) resonance vibration frequency of the steam system, and can effectively suppress the pressure vibration due to the acoustic resonance.
