摘要
研制了一种适用于板状燃料堆芯的黄玉改色装置, 并对辐照装置的物理安全特性及结构安全特性进行了分析。利用CFD多孔介质模型, 获得了改色装置的流场和温度场, 确定了功率限制因素, 并对装置进行了优化, 增强了中子选择材料的冷却能力, 结果表明, 优化后可在额定功率下进行黄玉改色试验。开展了改色装置的堆外水力学特性实验及冲刷试验, 装置工作压差附近的流量试验数据与理论模拟结果差别为-3.6%~1.9%, 二者一致, 冲刷试验表明, 装置对黄玉残渣有很强的包容、收集效果, 不会导致燃料元件流道堵塞。
Abstract
A new topaz color-alteration device suitable for reactors with plate fuel is developed. The physical and structural safety features have been analyzed. With porous medium model in CFD, the flow and temperature field were got, also the factor limiting the reactor operating power. The device improvement of enhancing the function material cladding’s cooling capacity were done. The results shows that the color-alteration experiment could be done at rated power after device improvement. The hydrodynamic characteristic experiment and CFD simulation data by the operation differential pressure were compared, with -3.6%-1.9% difference. The device washing test shows good ability to collect topaz residue, and the flow channel blockage is avoided.
