采用环形燃料可显著提高铅铋反应堆的堆芯功率密度,对实现反应堆小型化设计和经济性提高具有重要意义。本文基于闭式并联多通道模型和量子遗传算法,通过流量分配和热量分配的解耦计算,开发了铅铋快堆环形燃料热工水力分析程序;然后以燃料芯块最高温度、燃料包壳最高温度、内外出口温差、压降、堆芯功率为评价指标,采用多目标综合评价法开展了环形燃料组件最佳排列方式研究。结果表明:开发的铅铋快堆环形燃料热工水力分析程序与新加坡南洋理工大学开发的同类程序计算对比,结果误差在3%以内,流量分配和热量分配的解耦计算可在确保计算精度的基础上,显著提高程序计算效率;对于环形燃料组件最佳排列...

Background: Annular fuel can significantly increase the power density of the lead-bismuth reactor core, which is of great significance to realize miniaturized design of the reactor and fuel economy improvement. Purpose: This study aims to develop an annular fuel calculation program to obtain key thermal and hydraulic parameters, so as to obtain the optimal arrangement of annular fuel under different objectives. Methods: First of all, based on the closed parallel multi-channel model and quantum genetic algorithm, the thermal-hydraulic analysis p...
