加速器驱动次临界系统嬗变少锕系核素

MA Transmutation Using Accelerator DrivenSubcritical System

长寿命放射性废物的处置是影响核能发展的重要因素。在分析国外在这一领域的发展趋势的基础上，建议采用多用途加速器驱动铅冷快中子次临界系统嬗变少锕系核素（ＭＡ）的方案，并对ＭＡ嬗变链作了初步分析。这种系统在嬗变ＭＡ的同时，还能有效地生产电力和增殖核燃料，并且具有较好的安全特性。

Long lived radioactive waste disposal is an important issue for nuclear power development.Based on recent research in the field,a multi purpose accelerator driven,lead cooled fast neutron subcritical system is proposed,and MA transmutation chain is analysed.The system is able to transmute MA,generate energy,breed fissile materials,and has better safe characteristics.
