摘　　要：一体化快堆是一体化闭式循环快堆核能系统的简称,由钠冷快堆、金属燃料制造设施、乏燃料处理设施和废物整备设施组成,是快堆及其燃料循环系统的高级发展阶段,能够实现铀资源的高效利用和废物最小化,显著提升闭式核燃料循环的质量和效率。一体化快堆的最主要特征是核燃料的快速循环和多次循环,且核燃料的组成包括铀、钚和次锕系核素,可以称为全锕系核素循环。本文从反应堆核设计、燃料制造燃料成分控制方法、乏燃料处理回收率要求、燃料循环过程中物料辐射特性等方面,分析评估了一体化快堆全锕系核素循环的物理可行性。The Integral Fast Reactor(IFR)is a short form for the Integral Closed-cycle Fast Breeder Reactor nuclear energy system,which consists of a sodium-cooled fast reactor,metal fuel fabrication facilities,spent fuel reprocessing facilities,and waste conditioning facilities.It represents an advanced stage of development for fast reactors and their fuel cycle systems.It enables efficient use of uranium resources and minimization of waste,significantly improving the quality and efficiency of the closed nuclear fuel cycle.The most significant feature of the IFR is the rapid and multiple recycling of nuclear fuel,which includes uranium,plutonium,and minor actinides,allowing it to be referred to as the full-actinide nuclear fuel cycle.This paper analyzes and evaluates the physical feasibility of the full-actinide nuclear fuel cycle in the IFR from aspects such as reactor nuclear design,fuel manufacturing and control of fuel composition,requirements for the recovery rate of spent fuel processing,and material radiation characteristics during the fuel cycle.
