Abstract

Describes the software used in the calculation, according to the KIR2 program and the algorithms developed by the MAGMA group module (Group modulus taking into account anisotropic scattering). The results of the verification stage of the KIR2 program with a group physical module are presented. For verification, we used the C5G7 mathematical benchmark test, in which the energy field is divided into 7 groups. The results of comparison with the MCNP benchmark program on the effective breeding coefficient, confidence intervals and deviations from the benchmark program are presented. A comparison with other programs based on the Monte Carlo method (VIM and UNKMK and other independent calculations using the MCNP program) is also given. In addition, the use of the calculated data of the KIR2 program with high statistics as reference data for deterministic class codes (ATTILA, MCCG3D, CRX, PARTISN, UNKGRO) and programs based on the Monte Carlo method is presented. The analysis of the effectiveness of using comparison methods by deviations and confidence intervals is presented. The results of the verification phase of the KIR2 program with the MAGMA group module are summarized.
基于基准测试c5g7的kir2中子能量计算程序动力学中的群物理模块验证
介绍了根据KIR2程序和MAGMA群模(考虑各向异性散射的群模)开发的算法进行计算的软件。给出了基于分组物理模块的KIR2程序验证阶段的结果。为了验证,我们使用C5G7数学基准测试,其中能量场分为7组。给出了与MCNP基准方案在有效育种系数、置信区间和与基准方案偏差等方面的比较结果。并与其他基于蒙特卡罗方法的程序(VIM和UNKMK以及使用MCNP程序进行的其他独立计算)进行了比较。此外,还介绍了利用具有高统计量的KIR2程序的计算数据作为确定性类代码(ATTILA、MCCG3D、CRX、PARTISN、UNKGRO)和基于蒙特卡罗方法的程序的参考数据。对采用偏差和置信区间比较方法的有效性进行了分析。总结了利用MAGMA组模块对KIR2程序进行验证阶段的结果。
