Th/233U是核能发展中潜在的核材料。233U的中子数据在U-Th循环反应堆中是非常重要的数据。虽然已经评价给出了从10-5eV~20MeV的全套中子数据(CENDL-3.1),但是许多差别和矛盾仍然存在。为给出新的233U评价数据,首先调研了国内外233U实验测量和各国评价核数据库的现状,特别是最新发表的测量和评价数据,经过分析评价,改进和更新评价的CENDL-3.1。
Th / 233U is a potential nuclear material in the development of nuclear energy. The 233U neutron data is very important data in the U-Th Reactor. Although a complete set of neutron data (CENDL-3.1) from 10-5 eV to 20 MeV has been evaluated, many differences and inconsistencies still exist. In order to give a new 233U evaluation data, the author first investigated the current situation of 233U experimental measurement and nuclear evaluation database in different countries, especially the latest published measurement and evaluation data. After analyzing and evaluating, improving and updating CENDL-3.1.
