Cooling Power Plants Power Plant Water Use for Cooling ...

Most nuclear power (and other thermal) plants with recirculating cooling are cooled by water in a condenser circuit with the hot water then going to a cooling tower. This may employ either natural draft (chimney effect) or mechanical draft using large fans (enabling a much lower profile but using power*).

A simple model to help understand water use at power

heat that needs to be rejected; and therefore, less cooling water is required per kWh produced. Since between 85% and 95% of the total water needs in a thermal power plant are for cooling purposes [10] [11] [3], we can get a good estimate of the total water needs just by knowing the heat rate and the HR = Heat Input of Fuel Net Power Output ...

Cooling tower - Wikipedia

A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near ...
