Zusammenfassung:	A steam turbine system (11) includes a steam turbine (10) having a casing (11), into which steam is fed from the outside, and a rotating shaft (15) that is provided within the casing (11) so as to be rotatable around a central axis (Ac); a deaerator (50) that is connected to the steam turbine (10) and configured to deaerate leaked steam that has leaked from a gap between the casing (11) and the rotating shaft (15) to the outside of the casing (11); and a vacuum pump (60) that is connected to the deaerator (50) and configured to lower a pressure within the deaerator (50).
