Utility steam turbine package SST-9000

Evaluate this Device

The SST5-9000 is an exceptionally reliable steam turbine for applications in the conventional part of modern nuclear power plants (pressurized water reactors) with a capacity of 1000 MW to 1,900 MW.

The half-turn (25 turns per second) SST5-9000 consists of a double-flow high-pressure saturated steam turbine (HD) and up to three twin-flow low-pressure turbines (ND) with shrunk-on wheel disc rotors. Siemens low-pressure turbines with shrunk-on wheel discs represent technology that has been proven over decades. The result: no stress corrosion cracking and thus no replacement of the low-pressure rotor or wheel discs during the excepted service life.

  • Maximum reliability and availability

  • High operational flexibility

  • Low life cycle costs due to long inspection intervals

  • Extended lifetime, thanks to stateof-the-art engineering and proven service concepts
