摘要
改进型快谱超临界水冷堆(SCFR-M)具有紧凑的堆芯设计,堆芯内采用增殖组件与点火组件混合排布.增殖组件采用内冷式的圆形冷却剂通道,点火组件则采用典型三角形通道.本文基于CFD软件FLUENT采用流固共轭传热方式,分别对SCFR-M两种冷却剂通道内流动状态进行数值模拟计算,研究了稳态工况下SCFR-M堆芯设计的热工水力特性,计算结果表明:两种子通道中包壳表面温度均小于650℃、燃料芯块中心线温度均小于1 900℃,且流致振动程度在可接受范围内,符合安全设计限值.
An improved fast spectrum supercritical water cooled reactor （SCFR-M） with tight fuel pin arrangement is divided into seed and blanket region. The cylindrical water rod is used for the blanket assembly, and the triangular-array fuel rod bundle is used in the seed assembly. In this paper, thermal-hydraulic behavior of supercritical water in subchan- nel of SCFR-M has been investigated using computational fluid dynamics （CFD） code FLUENT. Results show that the maximum cladding surface temperature is below 650℃ and the fuel centerline temperature is below 1900 ℃ in two kinds of subchannel. And the level of flow-induced vibration is in the acceptable range.
