How much heat needs to be discharged into the environment versus how much can be used by the plant is usually a matter of operating temperature in the steam generators. In a coal or gas-fired plant, the internal boilers may be run at a higher temperature than plants containing precisely engineered nuclear fuel assemblies which could be damaged by excess heat. When it comes designing such power plants, the most optimal conditions should be considered for the most efficient running of the plant during normal operations. Location and environment are often key factors in deciding whether a wet or dry cooling system is preferable.
