摘要： A fuel assembly for a pressurized water reactor that has a protective grid attached to the bottom nozzle through a spacer insert captured between a control rod guide thimble end plug and the bottom nozzle. A thimble screw attaches the bottom nozzle to the control rod guide thimble end plug through a central opening in the spacer insert. The control rod guide thimble end plug is provided with a raised annular boss that encircles the thimble screw shank and rests against the upper surface of the bottom nozzle through the opening in the spacer insert. The opening in the spacer insert is large enough to provide both an axial and radial clearance between the spacer insert and the end plug to accommodate differences in thermal expansion.
摘要翻译：一种用于加压水反应器的燃料组件，其具有通过间隙插入件连接到底部喷嘴的保护网格，所述间隔件插入物被捕获在控制杆导向套筒端塞和底部喷嘴之间。套管螺丝将底部喷嘴通过间隔件插入件中的中心开口附接到控制杆导向套筒端塞。控制杆导向套筒端塞设有一个凸起的环形凸台，该环形凸台环绕套管螺杆，并通过间隔件插入件中的开口抵靠底部喷嘴的上表面。间隔插入件中的开口足够大以在间隔件插入件和端塞之间提供轴向和径向间隙，以适应热膨胀的差异。

摘要： The adaptor plate of a top nozzle assembly is removably secured to selected thimble tubes in a nuclear fuel assembly by quick release couplings. The openings in the adaptor plate aligned with the selected thimble tubes are counterbored from above to form shoulders with diametrically opposed slots extending downward through the shoulders. The quick release couplings include a sleeve secured to the upper end of the thimble tube. A support plate fixed to the sleeve has a pair of upwardly extending bosses engaging the slots in the adaptor plate. A latch member with a pair of diametrically opposed outwardly projecting latch ears rotates on the sleeve between a first position in which the latch ears are aligned with the slots and are positioned over the bosses so that the adaptor plate may be lifted off, and a second position with the latch ears overlaying the shoulder to latch the adaptor plate to the thimble tube. A spring member with a cylindrical body has a pair of diametrically opposed radially compliant projections formed by bulges in strips defined by circumferential slits spaced from the bottom edge of the cylindrical body which engage detents in the bosses to latch the latch member in the first, unlatched position even with the adaptor plate removed, and which engage detents in the opening in the adaptor plate to latch the latch member in the second, latched position.
摘要翻译：顶部喷嘴组件的适配器板通过快速释放联接器可拆卸地固定在核燃料组件中的选定的套管上。与所选择的套管对准的适配器板中的开口从上方沉入以形成具有向下延伸穿过肩部的直径相对的槽的肩部。快速释放联轴器包括固定到套管上端的套筒。固定到套筒的支撑板具有一对向上延伸的凸台，该凸台与适配器板中的狭槽接合。具有一对直径相对的向外突出的闩锁的闩锁构件在套筒之间在第一位置之间旋转，在第一位置中，闩锁耳与插槽对准，并且定位在凸台上方，使得适配器板可以被提起，并且第二位置与锁定耳覆盖肩膀，以将适配器板锁定到套管。具有圆柱形主体的弹簧构件具有一对直径相对的径向柔性突起，该凸起形成为由与圆柱体的底部边缘间隔开的圆周狭缝限定的凸起，其接合凸台中的棘爪，以将闩锁构件闩锁在第一未锁定即使在适配器板被移除的情况下，位置也接合在适配器板中的开口中的卡定位置以将闩锁构件锁定在第二锁定位置。
