钍铀循环关键核素的多群数据库加工与初步验证
Processing and preliminary testing on multi-group data file of pivotal nuclides in thorium-uranium cycle
摘要
Abstract
The development of advanced thorium-based nuclear system raises new requirements on nuclear data.The multi-group data file of critical nuclides in the thorium-uranium recycle is the foundation of physical design,analysis and calculation of the reactor core.Based on authoritative nuclear data processing code NJOY,this paper obtains a WIMS format multi-group cross section data files through processing the ENDF/B-VII.1 evaluation nuclear data file,uses the specific update maintenance proce-dure WILLIE to get a WIMS format data file,and conducts a series of critical benchmarks on the data file using the multi-group reactor core calculation code WIMSD5B.The results show that the computed results of the WIMS file based on the processing of ENDF/B-VII.1 are basically the same as those of the latest WIMS-D file published on the websites of the “WIMS-D”library up-dating project (WLUP)with higher accuracy and reliability than those of the shipped WIMS-D file of the WIMSD5B code.Fur-thermore,the average deviation of the new WIMS file performing in the validation of 1 6 thorium-uranium cycle benchmarks is 0.225 3% smaller than that of the old WIMS file.关键词
