Abstract: A core module for nuclear reactors includes a core support grid having hollow tubes extending upwardly therefrom and fuel assemblies mounted on the upper ends of said tubes with their interiors in communication with the interiors of the tubes. There are a number of control rods around the periphery of each module which are connected by a single control rod yoke, the control rods being guided on the outsides of the core support tubes. The yoke is connected to the core rod drive.

Abstract: A nuclear reactor control rod drive having relatively wide annular gaps for hydraulic fluid between relatively movable parts in the device. Guide structure associated with movable control pistons in the device provides for mounting of these pistons approximately concentrically within a guide tube and with less play with respect to this structure than the clearance between bearing surfaces at the guide tube. Hydraulic fluid at a pressure in excess of fluid pressure in the reactor can be selectively fed into the guide tube from the top of the tube for a rinsing operation.

Abstract: A control rod drive of the type wherein the load is actuated by a non-rotatable screwshaft driven axially within a sealed tubular enclosure includes a spinning nut assembly consisting of roller nuts mounted on pivoted segment arms and movable into and out of mesh with the screwshaft by energization and deenergization of an induction-type motor. The segment arms form a portion of the rotor so that when the field of stator rotates the roller nuts planetate to drive the shaft. A combined support and convectioncontrolling housing structure for the mechanism is adapted to be attached to the cover of a reactor vessel and includes an upwardly extending torque-taking piston-carrying section connected to the screwshaft and a snubbing cylinder for controlling the rate of descent and absorbing shock in event of scan, and means for parking the screwshaft in a raised position.

Abstract: An elongated shaft is axially assembled within a guide bearing which provides lateral support while permitting longitudinal movement. The bearing includes inwardly projecting ribs which intermesh with outwardly projecting splines from the shaft. Adjacent lateral guide surfaces of the ribs and splines are in slidable contact and each guide surface coincides with a radius from the longitudinal axis of the assembly. Space for unequal thermal expansion of the member and bearing is provided beyond the distal surfaces of the splines and ribs.
