摘要： The condenser which has a thin heat transfer pipe group, a main body trunk, and an intermediate trunk, and which generates condensed water by causing steam discharged from a steam turbine to flow from an upper section of the intermediate trunk, and by bringing the steam into contact with the thin heat transfer pipe group. In the intermediate trunk, upstream side heaters and downstream side heaters are arranged so as to be parallel to each other in a steam flowing direction. The downstream side heaters and turbine bypass pipes are arranged at the same position in the steam flowing direction. The length of a gap between the upstream side heaters and the downstream side heaters, and the turbine bypass pipes is set to be equal to or shorter than the radius of the turbine bypass pipes.
