摘要
针对第四代国际核能论坛提出的新概念熔盐堆堆芯的具体特点,采用DRAGON程序计算了堆芯轴向和径向功率分布因子,并对熔盐堆的燃料盐和石墨慢化剂分别建立数学模型,通过数值方法对新概念熔盐堆的稳态热工水力特性进行了模拟。计算得到了堆芯燃料盐的流量分配,代表元件内燃料盐和内外壁温度沿轴向的变化。
The Molten Salt Reactor （MSR） researched in this paper is one of the ＇Generation IV International Forum＇ concepts. The DRAGON code was adopted to calculate its axial and radial percent of the core power firstly. By founding the fuel salt model and graphite model respectively, the steady thermal-hydraulic characteristics of this Molten Salt Reactor core was simulated by numerical method. The results show the detailed flow distribution in the core, the temperature of the fuel salt, inner and outer wall in the representative elements.
