摘要

为了提高快堆物理分析的准确性，在ENDF/B-VIII的基础上建立了两个包含1968群中子和21群光子的库。0和ENDF/B-VII。1数据采用NJOY2016。开发了一个名为TXMAT2.0的代码来处理这两个库，以生成超细群中子和光子截面以及材料中的动能释放(KERMA)因子。为了对这两个库进行验证，选择ICSBEP基准进行关键验证，并选择样本1D基准。一些结果与参考数据吻合良好。对于rbc - m基准测试，基于超细群库的功率分配良好。

Development and Verification of Neutron and Photon Ultrafine Group Library for Fast Reactor Physical Calculation

In order to improve the accuracy of fast reactor physical analysis, two libraries with 1968-group neutron and 21-group photon were generated based on ENDF/B-VIII.0 and ENDF/B-VII.1 data by using NJOY2016. A code, named TXMAT2.0, was developed to process the two libraries to generate ultrafine group neutron and photon cross sections and Kinetic Energy Release in Material (KERMA) factors. To perform the verification of the two libraries, ICSBEP benchmarks for critical verification, and the sample 1D benchmark were selected. Several results were in good agreement with reference data. For the RBEC-M benchmark, the power distribution based on the ultrafine group library was good.
