Nuclear turbine is an essential component of a nuclear turbine island. For the pressurized water reactor, the usual design of the steam turbine entails an in-line combination of three low-pressure turbines and one high-pressure turbine. The turbines are designed as double flow system, with steam entering at the center and flowing to the ends. The steam passes through the control stage and a number of reaction stages, converting thermal energy to mechanical energy. The high moisture content in the steam exiting the high-pressure turbine usually reduces on passing through the stages of reheat and moisture separation. The low-pressure turbine is provided with moisture separator-reheater (MSR) units in parallel. After passing though the moisture separator section, the wet steam returns to steam generators.
