摘要
中国评价核数据库第二版（ＣＥＮＤＬ－２），包含从Ｈ到中的５４个重要核的全套评价中子核数据，中子能区为１０－５２０ＭｅＶ。它是在ＣＥＮＤＬ－１基础上，进行更新评价、扩展能区、扩充核素和数据种类；按国际标准格式建立计算机化核数据库；改进和发展理论计算、评价处理的有关方法和技术，研制配套相应的计算程序和基准检验程序系统；评价分析和理论计算细致，部分核的评价有自己的特色，较国际上先进的评价核数据库有所改进，有些评价数据还被这些先进库所采用。国际原子能机构已把ＣＥＮＤＬ－２作为国际上最先进的５个主要评价核数据库之一向世界各国发行，提供使用。
A complete set of neutron nuclear data . for 54 important nuclides from H to 249Cf has been e- valuated and recommended, with the incident neutron energy range from 1 0 - . eV to 20 MeV . The main features for CENDL-2 are as follows : on the basis of CENDL- 1 , was carried out the renewal evaluations, extended the energy region, supplemented the data type of evaluations, and added the new evaluations : established the computerized nuclear data library according to the in- ternational standard format : improved and developed the related theoretical methods and technolo. gy for nuclear data calculation. and evaluation processing : developed a complete set of the theoret- ical calculation codes with new ideas and our own distinguishing features : and formed a complete set of programs for nuclear. data processing and benchmark testing . With new experimental data, careful evaluation analysis and theoretical calculations, the evaluations for partial nuclides have our own distinguishing features to give significant improvement compared to the existing worldwide advanced nuclear data libraries. Some evaluations have been adopted by other ad- vanced libraries . The CENDL-2 has been released as one of the five main advanced evaluated nu- clear data libraries for users in the world by international Atomic Energy Agency .
