CANDU反应堆物理程序和方法

Physics Codes and Methods for CANDU Reactor

简要介绍了加拿大原子能公司（ＡＥＣＬ） 目前用于ＣＡＮＤＵ 反应堆物理设计和分析的计算机程序和方法。对栅元、超栅元和堆芯三种计算方法及相应的计算机程序进行了讨论。对物理分析中每层物理过程的理论表达和应用的求解方法也作了说明。实验验证的例子显示， ＡＥＣＬ 目前所用的物理程序和方法有较好的精度和较高的置信度。

This paper presents an overview of the physics codes and methods that are in current use at AECL for physics design and analysis of CANDU reactors.The 3 levels of calculations lattice cell,'Supercell' and finite core calculations are discussed,with references to the computer codes used in each step.The theoretical formation and representation of the physical processes at each level of the analysis and the solution methods used are also explained.The sample results of code validation demonstrate the good accuracy and a high level of confidence of the physics codes and methods.
