【摘要】 2006年发布的ENDF/B-Ⅶ.0评价库较2001年发布的ENDF/B-Ⅵ.8有许多改进之处,与临界积分检验装置实验结果符合得更好。采用NJOY程序及ENDF/B-Ⅶ.0评价库中子入射子库,制作了MCNP系列程序使用的ACE格式参数。阐述了新评价库的特点和参数库的制作过程,重点叙述了对参数库的检验。结果表明,制作的参数库是正确的,可供用户使用。更多还原

【Abstract】 ENDF/B-Ⅶ.0,released by the USA Cross Section Evaluation Working Group(CSEWG) in December 2006,was developed in five years since the previous release of ENDF/B-Ⅵ.8 and was demonstrated to contain much better physical representations of the data and to perform much better than previus ENDF evaluations over a broad range of applications.We generated ACE-format pointwise cross section library from the ENDF/B-Ⅶ.0 neutron reaction sublibrary with the processing code NJOY.The paper provides an overview of ENDF/B-Ⅶ.0,a summary of the ACE-format files producing process and a detail description of the validation of the ACE-format library.The conclusion is that the ACE-format library produced is correct.更多还原
