Proliferation-resistant Recycling
of Used Nuclear Fuel using Molten Salts

Concerns about proliferation have restricted the treatment or conditioning of used nuclear fuel before disposal or recycling, despite the benefits of reduced environmental footprint. We want to reinvent proliferation resistance in molten salt pyroprocessing for the safer, smaller, and cost-effective disposal of used nuclear fuel and radioactive waste as well as for the optimized fuel supply of advanced nuclear reactors.

생태발자국 감소의 이점에도 불구하고, 핵확산에 대한 우려로 인해 처분 혹은 재활용 이전의 사용후핵연료 처리와 관리는 제한적인 실정이다. 이에 본 연구팀은 용융염 파이로프로세싱의 핵확산 저항성을 재조명함으로써 개량형 원자로의 연료 공급 최적화에 더하여 더욱 안전하고, 소형화되었으며, 비용 효율적인 사용후핵연료와 방사성폐기물 처분을 달성하고자 한다.
