摘　　要：在验证加速器驱动系统的启明星实验装置的设计方案中,利用蒙特卡罗程序(MCNP)对有效增殖系数Keff进行了计算,并对与Keff密切相关的热区燃料元件栅距和热区厚度进行了最优参数的计算。结果表明,启明星实验装置的Keff能够达到设计的目标。Qimingxing experimental facility is designed to validate the principle of accelerator driven systems (ADS).Monte Carlo Code (MCNP) is used to carry out K_(eff) calculations.The thickness of thermal zone and the pitch of fuel rods in thermal zone are optimized.Calculation results show that the optimized design can meet the K_(eff) requirement of the facility.
