【摘要】 为满足堆内或核爆中链式反应过程的燃耗值的计算需要,对裂变谱中子和14 MeV中子诱发238U裂变的短寿命产物核的累积产额进行了评价。评价利用了所有可利用的实验数据,经物理分析后,使用AVERAGE程序加权平均,用ZOTT程序进行同时评价,给出了所要求能点的唯一最佳推荐数据,并将评价结果与ENDF/B-VII ,JEF-2 .2 ,JENDL-3 .2和CENDL-2的推荐数据进行了比较。评价结果将用于CENDL-2的更新与升级。更多还原

【Abstract】 For reliable and consistent nuclear calculation,the cumulative yields for short-lived fission products are evaluated based on the available experimental data for 238U fission induced by fission spectrum neutrons and ~14 MeV neutrons.The data are processed using codes AVERAGE for weighed average and ZOOT for simultaneous evaluation.The evaluated data are compared with those in the major international nuclear data libraries,including ENDF/B-VII,JEF-2.2,JENDL-3.2 and CENDL-2.The present evaluation will be used to improve and update the CENDL-2 library.更多还原
