摘要： An unlatching tool configured for actuating a movable section of a control rod drive shaft in a pressurized water reactor includes a base; a gripper assembly configured for gripping the movable section of the control rod drive shaft; a rod movably connecting the gripper assembly to the base; and a mechanical actuator fixed to the base and configured for rotating the rod to raise and lower the gripper assembly. A method for actuating a movable section of a control rod drive shaft includes installing an unlatching tool on the control rod drive shaft; latching the unlatching tool to a stationary section of the control rod drive shaft; and raising a rod connected to a gripper assembly to cause the gripper assembly to grip the movable section and move the movable section upward.

摘要： A gravity actuated gripper includes two concentrically interleaved shells ich are displaceable with respect to one another in two positions for gripping molds containing radioactive material, with the fill opening or upper edge of the molds being provided with a circumferential carrying ring behind which engage balls to perform the gripping. The gripper is intended to be particularly robust and assure high operational reliability under all conditions. For this purpose, a special control is provided for the two positions, the control including a switching ring which corresponds with rings of crown teeth attached to both shells. Due to the special configuration of the teeth and an up-and-down movement of the switching ring, the two shells can take on a gripping position and a release position.

摘要： A nuclear reactor includes a reactor core and a pressure vessel surrounding the reactor core. A plurality of tubes pass through the bottom part of the vessel and extend towards the core. These tubes have upper ends forming guide tubes for control rods. The core is formed of a plurality of core units each comprising a fuel assembly and a rod movable in one of the control rod guide tubes. The fuel assemblies are substantially polygonal in cross section and are arranged in a polygonal lattice. Each of the fuel assemblies rests on a separate control rod guide tube. The fuel assemblies are arranged close together with at most only a small gap between them and are laterally supported by the adjacent fuel assemblies and the control rod guide tubes.
摘要翻译：核反应堆包括反应堆堆芯和围绕反应堆堆芯的压力容器。多个管穿过容器的底部并朝着芯延伸。这些管具有用于控制棒的上端形成导向管。芯由多个芯单元形成，每个芯单元包括可在一个控制杆导管中移动的燃料组件和杆。燃料组件的横截面基本上是多边形，并且以多角形格架布置。每个燃料组件搁置在单独的控制杆导管上。燃料组件最靠近地布置在它们之间的最小的间隙处，并且被相邻的燃料组件和控制杆导向管横向支撑。

摘要： A system for gripping an inner tube and locking/unlocking it into and from an outer tube concentric with the inner tube. The system according to the invention is provided with one or more catching devices which allow both sealed locking/unlocking of the inner tube to the gripper member and of the inner tube in the outer tube, achieving this with only a translational movement of the gripper member over a travel A or a travel B. The system according to the invention advantageously constitutes a system for inserting and extracting a specimen holder tube intended to house a specimen of nuclear materials, such as nuclear fuels, into and from a measurement instrumentation holder tube intended to house measurement sensors and a cooling system.

摘要： The control rod (4) carrying absorbing elements (5) contains an operating rod (37) forced upwards by washers (38) and projecting by a push button end (52). When it is decided to uncouple the absorbing elements, the control rod (4) is raised, so that the teeth (62) of ratchets (56) opened out beforehand weigh on the push button (52), lower the operating rod (37) and enable coupling balls (33) to enter a groove (35) on the bottom of the rod, which detaches the pommel (18) carrying the absorbing elements (5). Application to pressurized water nuclear reactors.
