摘要： A pressurized water reactor plant includes a reactor vessel (1), a reactor coolant pump (5) having an inlet connected by coolant pipe (2) to an outlet of the reactor vessel, a steam generator (10) having an inlet connected by a high-temperature side pipe (4) to the outlet of the pump (5) and an outlet connected by low-temperature side pipe (6) to an inlet of the reactor vessel. The steam generator has a horizontally extending shell (11) in the interior of which are horizontal U-shaped tube bundles (30) supported on tube support plates (20) and a pair of separator plates (18) which divide the interior of the shell into downcomer space (19). A partition plate (21) divides the interior of the shell into a U-shaped tube region (16) and a straight tube region (17). A moisture separator (27) is disposed above the heat transfer tubes (15) and a drain pipe (28) extends therefrom for draining impurities from the moisture separator to the U-shaped tube region (16) to which blowdown pipe (26) is connected.

摘要： An emergency reactor coolant accumulator has a depressurizer to depressurize the accumulator at an appropriate timing, thereby preventing the flow of accumulator gas into the reactor system. If an accident occurs in the reactor system and the pressure of the reactor system decreases, the accumulator water (19) in the accumulator body (11), which is pressurized by the accumulator gas (18) is injected into the reactor system through the accumulator water outlet line (12) via the check valve (13) to cool the reactor core, and at the same time, the accumulator water (19) in the accumulator body (11) is introduced into the depressurizing vortex damper body (21) through the lower inlet (21c) of the damper (21) in the tangential direction to form a vortex. The increase in resistance due to the vortex reduces the amount of water discharged from the accumulator body (11) to the gas release line (22) via the depressurizing vortex damper (21). When the water level of accumulator water (19) drops below the lower inlet (21c ) of the depressurizing vortex damper (21), the accumulator gas (18) enters into the depressurizing vortex damper body (21) through the top inlet (21b) and the lower inlet (21c) and is released out of the reactor system through the gas outlet (21d) and the gas release line (22).
