摘要： According to an embodiment, a steam separator is provided with a barrel, a swirler, a pick-off ring, a steam collecting pipe and transverse pipes. A two-phase flow of steam and water ascends inside the barrel. The two-phase flow has a swirl force imparted by the swirler. Flow near the inner surface of the barrel is separated by the pick-off ring, etc. from flow near the center of the barrel and is guided so as to descend along the outer surface of the barrel. A major part of the flow near the center of the barrel is separated from the outside flow by the steam collecting pipe and guided to the outside of the barrel through the transverse pipes.

摘要： A pressurized water reactor comprises a reactor pressure vessel (11), a cylindrical core barrel (13), a core disposed in the core barrel (13), a lower core support plate (17), and a cylindrical porous plate (31). The core barrel (13) is provided in the reactor pressure vessel (11) and forms, with the inner side surface of the reactor pressure vessel (11), an annular downcomer (14) therebetween. The lower core support plate (17) is provided under the core so as to extend horizontally, and a large number of upward flow holes (80) are formed therein. The cylindrical porous plate (31) demarcates a lower plenum (16) and a bottom part of the downcomer (14), and a plurality of inward flow holes (83) that serve as flow paths from the bottom part of the downcomer (14) to the lower plenum (16) are formed therein. The inward flow holes (83) are inclined upward to the lower plenum (16) on the side on which the inward flow holes are open to the lower plenum (16).

摘要： There is provided a microbubble generating method including: supplying a gas to a rotator 2 while rotating the rotator 2 in a liquid; injecting the gas into the liquid from bubble injection holes formed in the surface of the rotator 2; and applying a shear force, produced by the relative movement between the liquid and the rotator, to gas bubbles present on and in the vicinity of the surface of the rotator 2 to generate microbubbles. The microbubble generating method can easily generate a large amount of microbubbles without forcibly creating a swirling flow of fluid.
