摘要
针对先进栅格中子学程序KYLIN-2的输运计算模块,开展了多个基准题数值验证,包括均匀介质基准题、Postma基准题、沸水堆(BWR)栅元基准题和C5G7组件基准题等。验证结果表明:射线间距对程序计算结果影响相对较小;方位角数目越多,计算精度越高,推荐的方位角数目应大于6;在选择适当的计算参数的前提下,程序输运模块具有较高的计算精度。
Several benchmark problems were validated for the transport calculation module of the advanced neutronics lattice code KYLIN-2, including homogeneous medium problem, Postma problem, BWR cell problem and C5G7 assembly problem. The validation results show that： （1） the ray spacing has limited effect on the calculation results, （2） the more the numbers of azimuth angle, the higher accuracy of the calculation, and the recommended azimuth angle number is greater than 6, （3） with the appropriate choice of calculation parameters, the transport module of the code has a high calculation accuracy.
