    摘要： A pressure-tube nuclear reactor can include an outer shell having an interior to contain a moderator at a first pressure and a coolant plenum to receive the coolant fluid at a second pressure, the second pressure being greater than the first pressure. The reactor also includes a plurality of pressure tubes. Each pressure tube is received within and extends through a corresponding shell tube and is configured to releasably retain at least one fuel bundle. A first end of each pressure tube being coupled to the plenum tubesheet in fluid communication with the plenum chamber and a second end of each pressure tube fluidly connected to a coolant conduit to enable the coolant fluid to flow between the coolant plenum and each pressure tube and to flow from the nuclear reactor for further processing.

    摘要： The present invention provides a chimney for a natural-circulation boiling water reactor having structural soundness capable of standing a horizontal load generated by a flow-induced vibration, an earthquake and the like. The chimney for a natural-circulation boiling water reactor according to the present invention is characterized in that: the chimney is disposed in the inside of a reactor pressure vessel, and includes plural flow channels which guide a steam-water two-phase flow generated in a reactor core to the upper part of the reactor pressure vessel; each of the flow channels is formed partitioned by plural flow channel separation walls whose lower-most part is supported by a chimney lattice plate; and chimney spacers that support the horizontal load each other are arranged between the flow channel separation walls of the adjacent flow channels, and ring-like members that support the horizontal load are arranged at the outermost periphery of the plural flow channels that are supported by the chimney lattice plate.

    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 (18) on the side on which the inward flow holes are open to the lower plenum (16).
