Steam Turbines for Nuclear Power Plants

Steam Turbines

Characteristics

Steam turbines for nuclear power plants employ an extremely long last stage blade (LSB), with the high pressure (HP) turbine, low pressure (LP) turbine and generator arranged along a single rotor, generating up to 1,800 MW. The turbines are designed to be extremely safe and reliable with efficiency among the highest in the industry.
