The conventional island (or turbine island) is the part of a nuclear power plant that is similar to a 'conventional' coal fired power station. It is non-nuclear and converts high pressure, high temperature steam to electricity, using one or more steam turbines and electrical generators. The essential parts of the conventional island are:
Steam Turbine converts steam into rotational energy. Electrical generator converts the rotational energy into alternating current electricity. Steam condenser condenses the exhaust steam back to water. Condensate-feedwater system collects the condensate and feeds the pressurised feedwater to the steam boilers in the nuclear island. Moisture separator fitted between the high pressure and low pressure turbines to remove droplets of condensed water that may cause damage to the low pressure turbine. cooling system removes residual heat from the steam condenser.
