Scenarios of Nuclear Energy Use in the U.S. for the 21st Century

This analysis investigates the potential range and timing of future nuclear energy contributions to the US energy system. The interactions of improved nuclear competitiveness through nuclear reactor capital cost reductions and alternative climate mitigation policies are explored to assess the potential expansion of nuclear power throughout the 21st century. Multiple long-term scenarios of the US energy system are generated using the PNNL GCAM model for clarifying the role of nuclear capital cost reductions, the role of carbon penalties and emission constraints, and their combined impact on the deployment of nuclear power and on carbon emissions in the US.
