摘　　要：文中给出了位于上空腔的中小尺寸接管破裂或安全阀意外开启引起的小破口失水事故的模拟实验研究情况。在实验中研究了系统压力,温度、空泡份额的变化和总失水量。总失水量约为初始装水量的20%。A Simulation Experiment of Small Break LOCA is introduced,whichwas caused by the breakdown of a small or middle size pipe located atupper plenum,or by unexpected opening the safety valve.In the experi-ment,the system pressure,temperature,void fraction and tatal loss ofwater were studied.The total loss of water was nearly 20% of initialloading water.
