Saturated steam turbine SST-9000

for power generation

The SST5-9000 is a highly reliable steam turbine for applications in the conventional islands of advanced pressurized water reactors, with a power output up to 1,900 MW. The half-speed SST5-9000 features a double-flow saturated steam high-pressure (HP) turbine and up to three double-flow low-pressure (LP) turbines with shrunk-on disk rotors. Shrunk-on disk design features proven technology: no stress-corrosion cracking that will require replacement of the low-pressure rotors or disks during the design life-time. Frequency 50 or 60 Hz •Inlet pressure up to 80 bar / up to 1,160 psi Inlet temperature up to 310 °C / up to 590 ° F •Last stage blade length: 50 Hz – 117 cm to 183 cm / 46 inches to 72 inches 60 Hz – 107 cm to 142 cm / 42 inches to 56 inches
