DESIGN AND SITING CRITERIA FOR ONCE-THROUGH COOLING SYSTEMS BASED ON A FIRST-ORDER THERMAL PLUME MODEL

摘要

The processes which control the distribution of excess temper-ature in the heated plume resulting from the discharge of a heated effluent into a natural waterbody are discussed, and the relative importance of each process for various plant design and environmental conditions is assessed. The distributions of excess temperature, and the time-temperature history of exposure of organisms entrained into the thermal plume resulting from the discharge of condenser cooling water from a 1000 MWE nuclear power plant, are given for several alternate sets of design criteria for the discharge structure.
