탈탄소화된 미국 전력 시스템에서 원자력의 미래 역할 (Nuclear Power’s Future Role in a Decarbonized U.S. Electricity System)
본 보고서는 탈탄소화된 미국 전력 시스템 내 기존 및 차세대 원자력 기술의 역할을 탐구합니다.
This study explores the roles of existing and next-generation nuclear power technologies in a decarbonized U.S. electricity system. Scenario analysis in four state-of-the-art electricity planning models explores the relative competitiveness of nuclear power across a wide range of policy and technology futures. Results from across the four models and scenarios reveal that disparate projections for nuclear power plant retirements are explained by different cost assumptions, and the economic deployment of new nuclear capacity requires a stringent emissions target or significant capital cost reductions. The combination of these drivers could result in substantial expansion of new nuclear power, which is operated more flexibly to complement widespread deployment of variable renewable energy technologies. Increasingly stringent emissions targets drive an evolution in the revenue streams for nuclear power plants and a pronounced increase in the cost point at which new nuclear capacity achieves competitiveness. More work is needed to refine cost projections and noneconomic factors that will influence the deployment of next-generation nuclear technologies.
