钍基重水核能系统燃料的物理特性研究

Research on Physics Characteristics of the Fuel for Thorium-based Heavy Water Nuclear Energy System

对全铀CANFLEX燃料和含钍CANFLEX燃料的物理特性进行了研究。用WIMS-AECL程序计算了参考栅元的冷却剂空泡反应性、燃耗等参数。通过与铀燃料的对比,展示了含钍燃料在安全性和经济性上的特点。还特别介绍了WIMS-AECL程序在使用过程中的参数选择方法。

This paper presents the research of physics characteristics of all-SEU and Thorium-SEU CANFLEX fuel. Some important parameters (coolant void reactivity, burn-up and etc.) are calculated using the code WIMS-AECL. Compared with uranium fuel, thorium fuel manifests its characteristics in safety and economics. This paper also introduces how to select the parameters when using WIMS-AECL code.
