为探索我国核裂变能可持续发展的新技术途径，利用MCNP5程序，建立了加速器驱动次临界系统（ADS）嬗变堆堆芯结构数学模型，模拟计算嬗变堆中分别使用氦气、液态铅、液态钠3种不同冷却剂对反应堆内局部中子能谱的影响，得出用液态铅作为ADS反应堆的冷却剂效果最佳的结论，提出了可提高嬗变堆内嬗变率的非均匀燃料组件排布的优化方案。

For exploring new technical approach of sustainable development of nuclear fission energy , the sub-ject used the MCNP5 program to establish mathematical model of accelerator driven system (ADS) transmuta-tion reactor core, and calculate influence on reactor local neutron spectrum of transmutation reactor , in which used three different coolant such as helium , liquid lead and liquid sodium.The results show that cooling effect of liquid lead is the best for ADS reactor , and then, a non-uniform optimization plan of fuel assembly is pro-posed to improve the reactor transmutation rate .
