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。

Abstract: 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 com- posed 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（k_eff=0.90～1.00）,the core fuel grid of thermal area is schemed out.
