摘　　要：本文针对典型钠冷快堆,采用钠冷快堆系统分析程序FR-Sdaso对其丧失蒸汽发生器模块后的不对称运行工况进行了分析计算,基于两种流量分配方式及稳态非对称模型,计算得到不同功率水平下的工况特征参数,包括不同环路的功率分配、主热传输系统节点温度等。通过对比分析,从可接受的最高功率水平、环路的对称性等多方面,对两种流量分配方式的优缺点进行对比总结。研究成果可为钠冷快堆丧失蒸汽发生器模块后的目标运行工况设计方法提供参考。In this paper,the sodium-cooled fast reactor system analysis code,FR-Sdaso,was used to analyze and calculate the asymmetric operating conditions of a typical sodium-cooled fast reactor after the loss of steam generator module.Based on two flow distribution methods and the steady-state asymmetric model,the characteristic parameters of the operating conditions under different power levels were calculated,including the power distribution of the different loops,and the key temperatures of the main heat transfer system,etc.The advantages and disadvantages of the two flow distribution methods were compared and summarized in terms of the maximum acceptable power level,the symmetry of the loops,and other aspects.The study results can provide a reference for the design method of target operating conditions after the loss of the steam generator module for sodium-cooled fast reactors.
