Abstract

The goal of the present invention is to efficiently absorb non-condensible gas and reduce the concentration of dissolved oxygen by lowering the level of the non-condensible gas such as dissolved oxygen in a water supply system of a boiling water reactor. The solution of the present invention is to send the steam generated in a reactor pressure vessel through a main steam line to a steam turbine in a boiling water reactor. The steam supplied for work is condensed in a condenser into water which is sent with a condensate pump through a heater and a deaerator to a feed water system. The boiling water reactor in which the reactor feed water circulates through the feed water system into the reactor pressure vessel includes a low pressure drain tank 213 for introducing part of steam/water heated with a heater through a steam/water inlet piping 1 and extracting non-condensible gas such as oxygen contained in the steam/water and sucking in an offgas extractor 216, so that steam water flowing into piping 1 penetrates through a tank wall into the low pressure drain tank 213. Around the piping 1 positioned in the tank, a plurality of flow holes 4 for discharging steam/water as droplets are provided with proper intervals.
