TP2008核数据库验证

TP2008是新研制的用于TPFAP程序的69群核数据库，本文利用IAEA压水堆棒状燃料组件基准问题和零功率临界实验结果对TP2008核数据库进行了验证分析。结果表明，燃料组件无限增殖因数k_∞与机构TUR的符合相对好；棒状燃料组件相对功率分布计算结果与参考程序的符合较好。零功率临界实验的堆芯有效增殖因数k_eff的相对偏差大部分在-0.5%以内，符合较好。

Verification of TP2008 Nuclear Data Library

TP2008 nuclear data library with 69 groups structure was generated for TPFAP code, and the verification of the TP2008 nuclear data library was made by analysis of IAEA benchmark problem with rod shape fuel assembly of PWR and zero power critical experiments. The numerical results indicate that the calculated values of fuel assembly infinite multiplication factor k_∞ are in good agreement with k_∞ of organization TUR, and the relative power distribution of PWR fuel assembly is in good agreement with that of referenced code. Most core k_eff relative deviations of the zero power critical experiments are less than -0.5%, and they are in good agreement with experiments.
