摘要 在截面库研制过程中,着重考虑了在反应堆设计与运行温度范围的温度点;使用NJOY软件将ENDF格式的中子截面文件处理为ACE(A Compact ENDF)格式的点截面文件,供MCNP程序使用。验证过程应用了3种不同类型的临界基准题:简单的球形几何基准题、板式燃料元件实验装置和带有可燃毒物的堆芯。结果表明,3种临界基准题所得到的验证结果均较为理想,在精确度方面也达到了要求。证明了使用NJOY制作截面库方法的正确性。 In this paper, the processing method of NJOY which transfers ENDF files to ACE (A Compact ENDF) files (point-wise cross-Section file used for MCNP program) is discussed. Temperatures that cover the range for reactor design and operation are considered. Three benchmarks are used for testing the method: Jezebel Benchmark, 28cm-thick Slab Core Benchmark and LWR Benchmark with Burnable Ab- sorbers. The calculation results showed the precision of the neutron cross-section library and verified the correct processing methods in usage of N JOY.
