摘要： The present invention discloses a flow control device, a waste heat discharge system, and a flow stabilization method. The flow control device includes a first pressure sensor, a second pressure sensor, a temperature sensor, a flow control valve, and a controller. The first pressure sensor, the second pressure sensor, the temperature sensor, and the flow control valve are disposed in a return line of a condensate liquid. The first pressure sensor, the second pressure sensor, the temperature sensor and the flow control valve are each communicatively connected to the controller. The present invention is capable of automatically controlling the liquid level in the return line of the condensate liquid by means of a flow control system formed by the first pressure sensor, the second pressure sensor, the temperature sensor, the flow control valve and the processor. In addition, by setting the flow control system in the waste heat discharge system, the liquid level is maintained near the outlet of the heat exchanger, thereby preventing the condensate water from impacting on a gas-liquid interface, achieving the effect of eliminating the fluctuation of the flow rate of the condensate water, and realizing the flow stabilization effect of the waste heat discharge system.

摘要： A pressure-loss adjusting-member installation tool (70) to be used at a time of assembly of a reactor including: pressure-loss adjusting-member grippers (80) each of which can freely grip or release a pressure-loss adjusting member, which is arranged at a position between a lower nozzle arranged at one end of a fuel assembly having a relatively small pressure-loss when light water used as a primary coolant flows and a lower core support plate, and can cause the light water to pass therethrough in a state with a pressure-loss being increased more than that of when the light water passes through only core support plate flow holes formed on the lower core support plate; and a frame (71) that holds a number of the pressure-loss adjusting-member grippers (80) in a same positional relationship as a relative positional relationship between the fuel assemblies arranged in plural on the lower core support plate.
