Abstract:
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.
