摘　　要：作为加速器驱动洁净核能系统(ADS)原理验证装置“启明星”一号的次临界驱动堆,堆芯采用快- 热耦合方式组成,由天然金属铀组成快中子能谱区能有效地嬗变锕系元素(MA),低浓铀元件组成热中子能谱区能有效地嬗变裂变产物(FP)。使用MCNP程序对次临界实验装置进行设计计算,确保keff在 0．90-1．00之间。As the sub-critical reactor of the verification facility “Venus I ” of Accelerator Driven System, the fast-thermal coupling project is introduced in its sub-critical core de- sign. The fast neutron energy spectrum area is composed of natural metal uranium com- ponents, the MA can be transmuted in this area; the thermal neutron energy spectrum area is composed of low density uranium components, the PF can be transmuted in this area. The critical calculation is carried out with 3-D Monte Carlo code （MCNP）. The calculating result （keff=0.90~1.00） shows that the facility design is reliable.
