摘　　要：“启明星”的次临界驱动堆是加速器驱动洁净核能系统(Accelerator Driven System,ADS)的原理验证装置．采用快-热耦合的堆芯组成方式,由天然金属铀组成快中子能谱区,低浓铀元件组成热中子能谱区。使用MCNP程序的U卡和Fill卡对次临界实验装置进行设计计算,根据k_(eff)在0．90～1．00之间的设计要求,确定了热区的燃料栅格。As the sub-critical reactor of the verification facility ＂Venus＂ of Accelerator Driven System, the fast-thermal coupling project is introduced in sub-critical core design. The fast neutron energy spectrum area is composed of natural metal uranium components; the thermal neutron energy spectrum area is composed of low-density uranium components. The critical calculation is carried out with Universe card and Fill card of 3-D Monte Carlo code（MCNP）. Based on the request of the verification facility （keff=0.90 - 1.00）, the core fuel grid of thermal area is schemed out.
