摘　　要：本文以船用反应堆为研究对象,利用RELAP5/MOD3.2程序建立一维系统模型,对蒸汽发生器给水故障引起的反应堆温度不对称偏环路运行进行计算分析。计算结果表明:蒸汽发生器给水故障时,反应堆压力容器的左、右环路进口冷却剂温差会出现大于10℃的情况;当蒸汽发生器维持给水流量小于40%时,反应堆的温度不对称偏环路运行会导致异常环路的蒸汽发生器压力、温度存在较大波动,不利于系统的运行控制和稳定。This article takes marine reactors as the research object and uses the RELAP5/MOD3.2 program to establish a one-dimensional system model to calculate and analyze the reactor temperature asymmetry partial loop operation caused by the steam generator feed-water failure.The calculation results show that:when the steam generator feed-water fails,the temperature difference between the inlet coolant of the reactor’s left and right loops will be greater than 10℃;when the steam generator maintains the feed-water flow rate of lea than 40%,the reactor temperature asymmetric partial loop operation will result in large fluctuations in the steam generator pressure and temperature of the abnormal loop,which is not conducive to the operation control and stability of the system.
