Estimating the term…
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 feedwater 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.
An apparatus for dampening vibration experienced by an object integrated with a structure within a reactor pressure vessel (RPV) of a nuclear power plant;
A system for reducing the vibration experienced by a pipe within a nuclear reactor pressure vessel (RPV), the system comprising:
