加速器驱动先进核能系统及其研究进展

Accelerator-driven Advanced Nuclear Energy System and Its Research Progress

针对现有商业反应堆核燃料利用效率低和乏燃料安全处置难等问题,中国科学院原创性地提出了加速器驱动先进核能系统(ADANES)的概念。对ADANES进行了初步物理研究,对超导直线加速器、高功率散裂靶、堆芯结构材料、乏燃料处理和新型燃料制备等进行了大规模前期计算与关键参数实验,论证了系统的可行性。目前,加速器驱动嬗变研究装置已得到“十二五”国家重大科技基础设施的支持,计划于2019年动工。

To address these challenges,including the low utilization rate of nuclear fuel and difficulties in safe disposal of nuclear spent fuels,Chinese Academy of Sciences proposed an accelerator-driven advanced nuclear energy system (ADANES).A lot of large-scale preliminary calculations and tests were carried out on superconducting linear accelerator,high-power spallation target,core structural material,spent fuel reprocessing and new fuel preparation.The feasibility of the principle was proved,and a series of laboratory simulation validations were completed and breakthroughs were made.At present,China initiative Accelerator Driven System (CiADS) has been supported by the “Twelfth Five-Year Plan” national major scientific and technological infrastructure,and is scheduled to start construction in 2019.
