Thermal Efficiency of Steam Turbine. In modern nuclear power plants the overall thermal efficiency is about one-third (33%), so 3000 MWth of thermal power from the fission reaction is needed to generate 1000 MWe of electrical power. The reason lies in relatively low steam temperature (6 MPa; 275.6°C).

Recirculating or indirect cooling. If the power plant does not have access to abundant water, cooling may be done by passing the steam through the condenser and then using a cooling tower, where an updraught of air through water droplets cools the water. Sometimes an on-site pond or canal may be sufficient for cooling the water.

Steam and Condensate - A basic overview of a steam system

Steam passes from the boiler into the steam mains. Initially the pipework is cold and heat is transferred to it from the steam. The air surrounding the pipes is also cooler than the steam, so the pipework will begin to lose heat to the air. Insulation fitted around the pipe will reduce this heat loss considerably.

Many newer power plants have cooling systems that reuse water

Once the steam has passed through the turbine at these plants, it must be cooled so it can condense back to a liquid and be returned to the boiler or steam generator. Plants that require the use of cooling water account for a little more than 70% of all the electricity in the nation and nearly 60% of the electric generating capacity.
