Abstract:
Seismic qualification test must be conducted for the valves which are used in the nuclear power stations. When the valves are qualified for the seismic qualification in the first time, the test method is available. Among the existence criterions of the seismic qualification for valves, the seismic qualification test includes single-frequency sine wave test, consecutive sine sweep wave test, multi-frequency wave method, and so on. In this paper, a type of valve is exampled by three methods of seismic qualification tests. Then, the results of the three methods are compared, which provide a wide ways and reference to improve seismic qualification for valves.
