中文摘要：

为研究低浓铀燃料在加速器驱动的次临界系统（ADS）中的应用,阐述了IAEA基准装置IPEN-MB-01,并使用MCNP程序对次临界装载的IPEN-MB-01基准装置进行了初步模拟计算,对该装置在低浓铀（LEU）燃料装载下的keff,由D-D或D-T外源驱动下的ks、中子通量分布和中子能谱进行了计算,并简单说明参数的计算方法。计算结果与其他参与计算的国家的结果进行了比较,结果相近。

英文摘要：

In order to verify the utilization of low enrichment uranium （LEU） in accelerator driven sub-critical system （ADS）, the IAEA benchmark facility IPEN-MB-01 was introduced. The MCNP code was used to simulate and calculate the parameters of sub-critical configuration of IPEN-MB-01. The keff and ks, neutron flux distribution, neutron energy spectrum of the facility which is driven by D-D or D-T external source were researched. The calculation method of parameters was explained. The comparison of data from different countries was performed.
