摘要
简要介绍了国际上发展中的核科学和技术及其应用对微观核数据的需求和核数据理论计算中现有标准程序的基本情况 ,并做了相应的分析和比对 .
Developing nuclear data needs towards to sustainable development on fission reactor design and many nuclear applications out the field of fission reactor technology that are growing economic significance and that have substantial data requirements are introduced. International standard codes used in nuclear data evaluation and calculation are presented and compared with each other. Generally speaking, three rather wide groups of nuclear reaction models used usually are also described. They are the formal theories of resonance reactions, generalized statistical models including fission, pre equilibrium and direct processes and combined with the optical model, and the intra nuclear cascade models. Recent progress of these nuclear reaction theories are given briefly, specially the recent progress of multi step compound and direct and state density are introduced in more detail.
