네거티브 배출 기술을 지원하기 위한 원자력 평가: 핵연료 주기 및 공급망 (Assessment of Nuclear Energy to Support Negative Emission Technologies: Nuclear Fuel Cycle and Supply Chain)
본 보고서는 네거티브 배출 기술(NET) 프로세스와 결합된 원자력 에너지의 실현 가능성과 성능을 조사하였습니다.
The feasibility and performance of nuclear energy coupled with Negative Emission Technology (NET) processes were investigated in this report. Three overarching questions from nuclear NET systems guided this research: which NET would be able to use heat and/or electricity from nuclear power plants (NPPs); what is the performance and cost of a nuclear NET system; and what would be the market outlook for this system?
Among the various NETs that are actively being developed, several were found to potentially benefit from coupling with an NPP via (1) large amounts of decarbonized and constant-output electricity; (2) free waste heat or cheap low-temperature heat; or (3) high-temperature heat. NPPs were found to be compatible with Direct Air Capture (DAC) systems, and a detailed techno-economic analysis of coupled NPP&DAC systems was performed. Preliminary analysis also indicated that biomass and water-based NETs are potentially compatible with NPPs, but further work is needed to quantify the performance of these nuclear NET systems.
