摘　　要：加速器驱动洁净核能系统(简称ADS)使用高能散裂中子驱动次临界反应堆,用于嬗变长寿命高放废物(LHW).ADS次临界反应堆中子能量较高,使用传统的ENDF截面数据库对ADS堆芯物理计算存在着能量上限低、部分数据缺失等问题.本文使用MAKXSF程序对IAEA-ADS截面数据库ADS Nuclear Data Library进行了加工,制作出专用于MCNP计算用的截面库ADSlib2.0,并与ENDF/B-VII.0,JEFF-3.1和JENDL-4.0库中238U裂变截面的比较,表明该截面数据库是可用的.Accelerator Driven System（ADS） is a sub-critical reactor driven by high energy spallation neutrons,which is used for Long-life High radioactive Waste（LHW） transmutation.Neutron energy in ADS is higher than traditional reactors,which limits in ENDF data is lower for ADS and some reaction cross-sections are missing.In this paper,ADSlib2.0 which is special ADS data for MCNP calculation is processed by MAKXSF using IAEA-ADS cross-section library.The comparison of fission cross-section of 238U between ADSlib2.0 and evaluated nuclear data libraries that include ENDF/B-VII.0,JEFF-3.1 and JENDL-4.0 shows that our cross-section library processing is applicable.
