摘　　要：通过试验对不同内置换料水箱初始水温条件下非能动余热排出系统(PRHRS)投入后堆芯进出口温度、一回路压力、PRHRS自然循环流量和换热功率等试验数据进行了对比分析。试验结果表明:IRWST初始水温较低时,堆芯模拟体进出口水温和压力下降更快,PRHRS热交换器(HX)出口温度低,PRHRS自然循环流量变化趋势基本一致,但换热功率更高。The PRHRS operation characteristics have been experimentally studied under different initial IRWST temperature conditions. The experimental results are compared in this paper, such as core inlet/outlet temperature, system pressure, exchange power. The comparison of the experimental nature circulation flow rate of PRHRS, heat results showed that the lower initial IRWST temperature caused the core inlet/outlet temperature and system pressure drop faster, the PRHR HX outlet temperature is lower but the heat exchange power is higher, the trends of nature circulation flow rate of PRHRS is similar.
