232Th 中子诱发裂变产额数据比对评价

232Th 中子诱发裂变产额在Th/U 燃料循环的核能开发中具有重要的意义，在现有国际评价产额数据库基础上，结合最新的实验数据，对产物核的质量分布和反应堆计算所需的重点产物核进行了比对。这些产物核包括95Mo，99Tc，101Ru，103Rh，109Ag，133Cs，147Sm，149Sm，150Sm，151Sm，152Sm，143Nd，145Nd 和153Eu 等，对有分歧的133Cs，152Sm 和153Eu 累积产额数据进行了评价调整。最后推荐给出了n+232Th 裂变的产额数据库，作为CENDL 库的组成部分。The yields of n+232Th fission are important in study of the Th/U fuel cycle. Based upon the evaluated nuclear data libraries and recent experimental data，comparison and evaluation for yield mass distribution and cumulativeyield were performed for those products are needed and important in reactor calculations，including 95Mo，99Tc，101Ru，103Rh，109Ag，133Cs，147Sm，149Sm，150Sm，151Sm，152Sm，143Nd，145Nd adn 153Eu etc. Adjustments were made for 133Cs, 152Sm and 153En which have discrepancies among the libraries. Database for n+233Th fission yield is recommended as a part of CENDL update.
