ABSTRACT:
A main steam line apparatus of a boiling water nuclear reactor plant including piping for introducing a steam produced in a pressure vessel into a turbine, a main steam valve for rapidly stopping the steam being supplied to the turbine through the piping, and a header. The header is located in the piping between the pressure vessel and the main steam valve. The header causes the pressure wave which occurs when the main steam valve is rapidly closed to be attenuated and an increase in pressure vessel pressure to be suppressed.
