摘要： A method and apparatus for a Boiling Water Reactor (BWR) jet pump slip joint internal seal for an interface between an inlet mixer and a diffuser of a jet pump assembly. The internal seal effectively mitigates leakage and slip joint flow induced vibration (FIV) between the inlet mixer and diffuser to reduce damage to many of the jet pump assembly components. A metallic seal of the slip joint internal seal flares out to conform the internal seal to a range of gap sizes, and compresses or springs back to nominal dimensions as thermal expansion and contraction occurs. The internal seal is self-expanding/self-tightening, as the internal seal flares further outward as a result of the internal pressure caused by flowing fluids in an operating jet pump assembly.

摘要： A method and apparatus for providing a Boiling Water Reactor (BWR) jet pump slip joint internal seal in the interface between an inlet mixer and a diffuser of a jet pump assembly. The internal seal provides an effective means of mitigating leakage and slip joint flow induced vibration (FIV) between the inlet mixer and diffuser to reduce damage to many of the jet pump assembly components that may otherwise be damaged by FIV. A metallic seal of the slip joint internal seal flares out to conform the internal seal to a range of gap sizes, and may be compressed or spring back to nominal dimensions as thermal expansion and contraction occurs. The internal seal is also self-expanding/self-tightening, as the internal seal flares further outward as a result of the internal pressure caused by flowing fluids in an operating jet pump assembly.

摘要： An embodiment of the present invention may reduce the level of vibration experienced by a line, such as, but not limiting of, a pipe, a cable, tubing, or the like, that is connected to at least one separate structure. For example, but not limiting of, the structure includes: a reactor pressure vessel, a sparger pipe, steam generator, a pipe, a pressure vessel, a heat exchanger, a pump, a condenser, a tank, or the like. An embodiment of the present invention may provide support and a preload to the line at a new location or may replace an existing support, such as, but not limiting of, a weld; which may alter the natural frequencies to avoid resonance from occurring when the structure(s) is excited.
摘要翻译： 本发明的一个实施例可以降低与至少一个单独的结构连接的管线，电缆，管道等的管线（例如但不限于）所经历的振动水平。 例如但不限于，结构包括：反应堆压力容器，喷射管，蒸汽发生器，管道，压力容器，热交换器，泵，冷凝器，罐等。 本发明的一个实施例可以在新的位置处为线路提供支撑和预载荷，或者可以替换现有支撑件，例如但不限于焊接; 这可以改变固有频率以避免当结构被激发时发生共振。

摘要： A mechanical connection between adjacent components of a system may include a first component of the system, a second component of the system, and a multiple degree-of-freedom connection between the first and second components. The multiple degree-of-freedom connection may have at least four degrees of freedom. A method for establishing a mechanical connection between adjacent components of a system may include disposing a first component of the system adjacent to a second component of the system, and connecting the first component to the second component using a multiple degree-of-freedom connection. The multiple degree-of-freedom connection may have at least four degrees of freedom.
