Why don't power plants use salt water when producing

Power plants use distilled water (pure as possible) in their steam turbines. Impurities, especially salt, would corrode the turbines at the high temperatures and pressures at which they operate. These plants generally use some manner of heat exchanger to cool off the fresh water steam and condense it back into water so that it can be recycled back into the boilers.
