| 中文摘要: |
| 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 subchannel 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. |
