摘要： A nuclear reactor system that, in one embodiment, utilizes natural circulation to circulate a primary coolant in a single-phase through a reactor core and a heat exchange sub-system. The heat exchange subsystem is located outside of the nuclear reactor pressure vessels and, in some embodiments, is designed so as to not cause any substantial pressure drop in the flow of the primary coolant within the heat exchange sub-system that is used to vaporize a secondary coolant in another embodiment, a nuclear reactor system is disclosed in which the reactor core is located below ground and all penetrations into the reactor pressure vessel are located above ground.

摘要： A riser cone has a lower end sized to engage a cylindrical lower riser section of a nuclear reactor and an upper end sized to engage a cylindrical upper riser section of the nuclear reactor. The riser cone defines a compression sealing ring that is compressed between the lower riser section and the upper riser section in the assembled nuclear reactor. In some embodiments the riser cone comprises: a lower element defining the lower end of the riser cone; an upper element defining the upper end of the riser cone; and a compliance spring compressed between the lower element and the upper element. In some embodiments the riser cone comprises a frustoconical compression sealing ring accommodating a reduced diameter of the upper riser section as compared with the diameter of the lower riser section.

摘要： A locking device for use in restraining a jet pump downcomer of a nuclear reactor, including an upper jaw; a lower jaw placed in an opposing position below the upper jaw; and a tightening screw movably supporting the upper jaw and the lower jaw. When installed on a jet pump downcomer, the complete assembly includes a restraining ring; a downcomer carried by the restraining ring; a wedge supported by the restraining ring and the downcomer; and a guide bolt extending in an axial direction in relation to the downcomer such that the wedge is movably supported by the guide bolt. The wedge is interposed between the upper jaw and the lower jaw, and one end of the upper jaw and a corresponding end of the lower jaw are moveably supported by the guide bolt. The upper jaw and lower jaw are supported at their respective opposite ends by the tightening screw. When the tightening screw is adjusted to cause the upper jaw and lower jaw to move toward one another, the bottom surface of the recess is brought into contact with the retaining ring. This action forces the wedge and restraining ring into frictional engagement, resulting in the wedge being firmly held against the downcomer. Thus, this frictional engagement causes the downcomer, wedge, and restraining ring to be secured in a desired position.

摘要： A top guide to shroud head interface is described. In one embodiment, the interface includes a top guide that includes a flange that is configured to engage a corresponding flange of the shroud head. The top guide flange includes a plurality of frusto-conical shaped guide pins extending from the top surface of the flange. The shroud head flange includes a plurality of guide pin openings configured to align with the guide pins located on the top guide flange. Each guide pin opening includes a frusto-conical portion that extends through the flange from the bottom surface of the shroud head flange and has a slope equal to the slope of the frusto-conical pins. Each guide pin opening also includes a cylindrical portion that extends from the small base of the frusto-conical portion of the guide pin opening to the top surface of the shroud head flange. The diameter of the frusto-conical guide pin opening at the bottom surface of the shroud head flange is configured to be larger than the diameter of the frusto-conical guide pin immediately adjacent the top surface of the top guide flange. The frusto-conical guide pins and guide pin openings provide for suitable clearances between the guide pins and the guide pin openings to accommodate any flexing of the shroud head flange during installation.
摘要翻译：描述了护罩头部接口的顶部导板。在一个实施例中，接口包括顶部引导件，其包括被构造成接合护罩头部的相应凸缘的凸缘。顶部导向凸缘包括从凸缘的顶表面延伸的多个截头圆锥形导向销。护罩头凸缘包括多个引导销开口，其构造成与位于顶部引导凸缘上的引导销对准。每个引导销开口包括截头圆锥形部分，其从护罩头凸缘的底表面延伸穿过凸缘并且具有等于截头圆锥销的斜率的斜率。每个引导销开口还包括圆柱形部分，其从引导销开口的截头圆锥形部分的小基部延伸到护罩头凸缘的顶表面。在护罩头凸缘的底表面处的截头圆锥形引导销的开口的直径被构造成大于紧邻顶部导向凸缘顶表面的截头圆锥形引导销的直径。截头圆锥形导销和导销开口提供导向销和导向销开口之间的适当间隙，以适应安装期间护罩头凸缘的任何弯曲。

摘要： A steam generator originally having hydraulic snubbers damping lateral thermal movement of the steam generator is backfit to laterally support the steam generator without hydraulic damping. Hydraulic fluid is emptied from piston cylinders of all snubbers extending from a steam generator; and then stops are placed around piston rods extending into the piston cylinders of empty snubbers extending from the back side of the steam generator to stop the thermal growth of the steam generator in the operation of the nuclear reactor vessel to generate power. Thus, the costs associated with maintaining, inspecting and testing hydraulic snubbers are entirely eliminated. Also, the backside empty snubbers are used as bumpers and do not incur disposal costs.

摘要： A pressure tank construction for nuclear reactors includes a steel tank which is inserted into a concrete enclosure. A clearance is provided between the steel tank and concrete enclosure when the steel tank is unpressurized and at ambient temperature. Under operating conditions, the steel tank expands and bears against the concrete enclosure. A support and insulatory means is also provided between the steel tank and the concrete enclosure.

摘要： A LOWER RADIAL SUPPORT SYSTEM IS PROVIDED FOR A NUCLEAR REACTOR INTERNALS WHICH PERMITS FREE RADIAL AND AXIAL DIFFERENTIAL EXPANSION WHILE PREVENTING THE LOWER END OF THE INTERNALS FROM MOVING OFF CENTER DUE TO VIBRATION OR EARTHYQUAKE SHOCK. ONE EMBODIMENT INCLUDES A PLURALITY OF INCONEL PLATES WELDED TO THE BOTTOM OF THE REACTOR PRESSURE VESSEL AND AN INCONEL CENTERING SLEEVE, THE UPPER END OF WHICH IS FITTED TO THE BOTTOM SUPPORT PLATE FOR THE REACTOR CORE IN SUCH A WAY AS TO HAVE AN INTERFERENCE FIT ON THE INSIDE DIAMETER OF THE SLEEVE AT OPERATING TEMPERATURE. THE LOWER END OF THE SLEEVE IS FITTED TO THE PLATE STRUCTURE WITH A TAPERED FIT TO PERMIT VERTICAL DIFFERENTIAL EXPANSION OF THE REACTOR INTERNALS.
