Future Climate Projections for Dry and Wet Condenser Cooling Options

This project will evaluate potential climate impacts in the northwestern United States from climate models and use those results to model plant performance using various cooling options. The results will be used to determine the range of plant performance and cost distributions to help understand the factors that need to influence the selection of a ultimate heat sink for a nuclear reactor in the region.
