摘要： The multiple fuel rod gripper comprises a plurality of split tube collets arranged to be inserted into corresponding tapered holes in a locking plate. When the gripper has been positioned to have a plurality of fuel rods disposed in the holes of locking plate, an actuating mechanism causes the collets to be inserted into the tapered holes thereby causing the fuel rods to be inserted in the collets. The taper of the holes forces the collets into locking engagement with the fuel rods so that the fuel rods may be extracted from the fuel assembly.
摘要翻译：多个燃料棒夹具包括多个分裂管夹头，其布置成插入到锁定板中的对应的锥形孔中。当夹具已经被定位成具有设置在锁定板的孔中的多个燃料棒时，致动机构使得夹头插入到锥形孔中，从而使燃料棒插入到夹头中。孔的锥度迫使筒夹与燃料棒锁定接合，从而燃料棒可从燃料组件中取出。

摘要： A wire is wound around an elongated support and a series of successive electric arcs is struck between at least one electrode in a transverse plane of the support and the wire, in such a way that the latter is struck by at least one of the arcs. A hollow member having a bevel shaped end raises the downstream part of the wire and a tubular member prevents the upstream part of the wire to be moved too far away from the support.

摘要： The spent fuel consolidation system provides a system for vertically and remotely dismantling an irradiated nuclear fuel assembly while the fuel assembly remains submerged in a coolant and for consolidating the spent fuel rods of the dismantled fuel assembly. The system comprises a platform rotatably mounted on a vertical support with a fuel assembly station, a consolidation station, and a canister station attached to the platform. A gripper mechanism is slidably disposed on the vertical support for transferring spent fuel rods from one station to another as the various stations are rotated into alignment with the gripper mechanism. The fuel assembly station provides a station for holding the fuel assembly while the spent fuel rods are removed therefrom, the consolidation station provides a station for consolidating the spent fuel rods, and the canister station provides a station for holding the consolidated spent fuel rods.

摘要： A fuel assembly includes a bundle of vertical fuel rods. Some of the rods are tying rods provided with extended upper end plugs, and the rest of the rods are spring-furnished ones, the spring forces balancing the tying forces exerted by the tying rods between a top plate and a bottom plate. The top plate is grid-like and provided with attachment holes for the upper end plugs. The lower end plugs of the tying rods are screwed in threaded holes in the bottom plate. Each of the upper end plugs of the tying rods has a portion located above the top plate and provided with a nut. Rotation of the nut is limited by at least one downwardly directed projection on the nut, the end surface of which lies below the upper edge of the top plate. The maximally allowable length of this projection is less than the maximum shortening of the springs that can be carried out by exerting a downwardly directed force on the top plate. With such a projection length the projections can clear the side and the nut can be rotated and removed.
摘要翻译：燃料组件包括一束立式燃料棒。一些杆是带有延伸的上端塞的捆扎杆，其余的杆是弹簧的，弹簧力平衡由顶板和底板之间的捆扎杆施加的捆扎力。顶板是格子状的并且具有用于上端塞的附接孔。捆扎杆的下端插头拧入底板的螺纹孔中。捆扎杆的每个上端塞具有位于顶板上方并设有螺母的部分。螺母的旋转受到螺母上的至少一个向下指向的突起的限制，螺母的端表面位于顶板的上边缘的下方。该突起的最大允许长度小于可以通过在顶板上施加向下的力来执行的弹簧的最大缩短。通过这样的突出长度，突起可以清除侧面并且可以旋转和移除螺母。

摘要： A nuclear reactor fuel assembly having an easily dissassembled threaded connection between the end fitting and the control rod guide tubes. More specifically, the threaded connection is formed between the upper and/or lower alignment posts and the guide tubes and clamps the fuel assembly end plate therebetween. The sizing and arrangement of the connections is such that the assembled joint may be subjected to thermal cycling without incurring excessive stresses or deformations.
