摘要： A method and apparatus for providing a Boiling Water Reactor (BWR) jet pump three point slip joint clamp to mitigate sleep joint leakage flow induced vibration of a BWR jet pump assembly. A collar, provided as one seamless component or in separate portions, is installed on the upper crown of a diffuser. The collar includes a lower set of fasteners and an upper set of fasteners that contact the inlet mixer and diffuser, respectively, to horizontally stabilize the inlet mixer in a fixed position inside of the diffuser. The upper fasteners may be anchored by bosses that ensure a light-weight design of the collar. An optional cantilevered seal (including a cantilevered overhang and a lip) may mitigate leakage from the slip joint interface.

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。
