Abstract: A fuel assembly for a nuclear reactor cooled by a moderating fluid. The assembly has flow tubes that extend beyond the inlet of the assembly and provide positioning and support structure when the assembly is mounted in the reactor. Flow is regulated through the flow tubes by orifices upstream of these tubes.

Abstract: Control line penetration of a nuclear reactor pressure vessel is achieved through the side of the vessel below the junction of the vessel main barrel portion and the reactor head. The control lines enter the pressure vessel in the form of a bundle of conduits at a point which is out of the main coolant flow path and the control lines are provided with disconnect means internally of the vessel.

Abstract: A core shroud comprised of a plurality of vertically stacked cylindrical thermal shields resting on a core support plate. Horizontal plates closely conforming to the core shape are sandwiched between each thermal shield. The inner thermal shield sections have vertical plates in the form of angles welded to the interior in a manner generally conforming to the periphery of the core. An outer thermal shield surrounds each of the inner thermal shields. Vertical tie bolts located in the annular space between the two shields maintain a resiliently compressive force on the stacked array of thermal shield and horizontal plates. A core support barrel surrounds the shield and the structure has openings to permit downward flow of some of the coolant through the various annular spaces formed by the shields prior to passage of coolant through the core.

Abstract: A protective shield for a nuclear reactor vessel is disclosed that is operative to reduce the impact strength of high pressure fluid released as a result of a reactor accident and also to prevent the expulsion of high velocity fragments from the vessel. The shield is constructed of a plurality of independent cylindrical rings that are axialy secured by tie rods. The tie rods are adapted to expand in the event of an inordinate buildup of pressure behind the shield whereby the rings can be displaced to create narrow openings through which the fluid can be released at a reduced rate.

Abstract: An automatic release for nuclear reactor control rod actuating mechanism carried by a removable, nuclear cooled vessel head. A reciprocable telescope with a control rod extension and is releasable connected thereto by spring pressed transversely sliding latches in the actuator. Near the bottom of the actuator stroke stationary tape pines enter axially extending holes in the actuator and start to enter misaligned holes in the latches have automatically withdrawn the latches and disconnected the rod extension so that the head and actuator may be removed as a unit leaving the control rod in the rector. Upward movement of the actuator form the bottom of its stroke with the head in place will move this actuator away form the taper pins and automatically release the latches and latch the actuator to the control rod.
