摘要： A method and apparatus for a boiling water reactor (BWR) jet pump inlet mixer compliant stop. The inlet mixer compliant stop may be installed in a pocket area between a riser pipe and an inlet mixer of a BWR jet pump assembly. The inlet mixer compliant stop includes a main body and a foot that are separated via the tightening of one or more jacking bolts used to connect the main body and the foot. A cold spring attached to the main body provides a lateral force that is imparted on the inlet mixer, to force the inlet mixer away from a centerline of the riser pipe. A precise lateral force may be imparted on the inlet mixer by gauging a width of a gap between opposing bosses on a front face of the main body and a distal end of the cold spring. The inlet mixer compliant stop imparts a greater lateral force on the inlet mixer as the jacking bolts are tightened, further separating the main body from the foot, as the gap between the opposing bosses is reduced.
摘要翻译： 沸水反应堆（BWR）喷射泵入口混合器顺应停止的方法和装置。 入口混合器兼容止动件可以安装在提升管和BWR喷射泵组件的入口混合器之间的口袋区域中。 入口混合器兼容止动件包括主体和脚，其通过紧固用于连接主体和脚的一个或多个顶起螺栓而分离。 附着在主体上的冷弹簧提供了一个在入口混合器上施加的横向力，以迫使入口混合器远离提升管的中心线。 可以通过测量主体前表面和冷弹簧的远端上相对的凸台之间的间隙的宽度来在入口混合器上施加精确的横向力。 入口混合器顺序停止在入口混合器上施加更大的横向力，因为顶起螺栓被紧固，当相对的凸台之间的间隙减小时，进一步将主体与脚分离。

摘要： Apparatus for supporting the lower elbow assembly of a jet pump in a reactor pressure vessel (RPV) of a nuclear reactor are described. The clamp apparatus includes a lower clamp element and an upper clamp element. The upper and lower elements are configured to be positioned at the interface between the thermal sleeve and the jet pump riser elbow. The upper and lower elements include extended ridges that are configured to fit in circumferential grooves precisely machined into the sleeve-elbow assembly on opposing sides of the interface.

摘要： A T-box assembly to facilitate attaching a core spray line to a reactor core spray nozzle safe end without welding is described. In one embodiment, the T-box assembly includes a T-box housing, a cruciform wedge, and a draw bolt. The T-box housing is configured to be positioned so that a first end is located inside a core spray nozzle and engages the core spray nozzle safe end. Two other ends are configured to be in substantial alignment and configured to couple to core spray line header pipes. The T-box housing also includes a cover opening configured to receive a T-box cover plate. The T-box cover plate includes a draw bolt opening configured to receive the draw bolt. The first end of the T-box also includes a plurality of positioning lugs configured to engage the core spray nozzle to center the T-box housing in the nozzle bore. The cruciform wedge includes four web members extending from a central member and configured so as to form an X shaped configuration. Two support members extend between the ends of adjacent web members and are configured to conform to the bore of the core spray nozzle safe end. The draw bolt is configured to extend through a cruciform wedge bore and the draw bolt opening in the T-box cover plate and to threadenly engage a draw bolt nut.

摘要： The weld reinforcement includes a generally dogbone-shaped pocket having laterally enlarged end portions and a reduced intermediate portion spanning a weld seam. A complementary-shaped reinforcing element is received in the pocket. The pocket includes a projection which is received in an opening in the overlying reinforcing element. A wedge-type clamp retainer is received about the projection within the opening to secure the element within the pocket.
