介绍了群常数库ＴＰＬＩＢ－９４的临界实验分析．ＴＰＬＩＢ－９４库是为轻水堆燃料组件计算程序包ＴＰＦＡＰ制作的，它基于ＪＥＮＤＬ－３．１评价核数据库。本文给出了５个热堆基准问题和一批压水堆零功率临界实验的计算结果．同实验结果的比较表明，利用该库，堆芯Ｋｅｆｆ的计算值与实验值的偏差小于０．４％，明显地小于利用旧库的相应偏差．
The critical experimental analysis of the group constant library TPLIB-94 is introduced. The TPLIB-94 library is built for the light water reactor fuel assembly calculation package TPFAP and is based on the JENDL-3.1 Evaluation Nuclear Database. In this paper, five thermopile benchmarking problems and a batch of zero-power critical experiments for PWR are given. The comparison with the experimental results shows that the deviation between the calculated value and the experimental value of the core Keff is less than 0.4%, which is obviously smaller than the corresponding deviation of the old library.
