摘要： A boiling water reactor comprises a reactor pressure vessel accommodated in a vertical fashion, a core disposed at a low portion in the reactor pressure vessel, a plurality of control rods to be inserted from an upper side of the core into the spaces between adjacent fuel assemblies and withdrawn therefrom upwardly, a shroud surrounding the fuel assemblies so as to define the core and having an upper end opening, a shroud head which closes the upper end opening of the shroud and through which the control rods are inserted or withdrawn, a separator standing upward from the shroud head to carry out gas-water separation of steam generated from the core, a fixing pedestal disposed above the separator, a control rod driving mechanism mounted on the fixing pedestal and adapted to drive the control rods, a drier unit including a plurality of drier elements annularly arranged along an upper inner wall surface of the reactor pressure vessel and adapted to dry the steam passing through the steam flow hole of the fixing pedestal, and a jet pump unit disposed in a space between an outer surface of the shroud and an inner wall surface of the reactor pressure vessel.

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.
