TPLIB－94库的临界实验检验

Critical Experiment Testing of TPLIB-94 Library

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．

This paper introduces the critical experiment testing of TPLIB-94 library. The TPLIB-94 was produced for LWR fuel assembly calculation program TPFAP, based on the JENDL-3. 1evaluated nuclear data library. In this paper, the calculation results and the measurement values of the 5 thermal reactor benchmark problems and a set of PWR critical experiments are presented. The comparison of these results show that the deviations of the core Reff values calculated using TPLIB-94 and the experiment values are less than 0. 4%, they are obviously less than that of the values using old library.
