This is basic information about steam turbines, you can find them in both fossil and nuclear power plants. The basic principles are still the same, only nuclear turbines are bigger, as the inlet temperatures and pressures are lower and to keep same steam velocity you need to increase size. Steam turbine is still the most powerful machine build by mankind so far.
These parameters are only common values and there are turbines with different parameters.
Power:
up to 1900 MW
Efficiency: about 95% for IP Turbine, 88% for LP Turbine
Pressure ratio:
4000:1 for an average turbine
20 000:1 for an advanced turbine in cold climate
Steam speed: Mach 2.0
Steam Temperature: 580 Deg C
- 4% of the steam energy is consumed by turbine, 96% of the energy is used to generate the power.
