Under a hypothetical lost of coolant accident of nuclear reactor,it may cause critical flow due to the pressure down sharply and the coolant vapors at the break.The flow characteristics have a great influence on the accident sequences and coolant inventory of the reactor core.Then it has a significant influence to the temperature of components.So the study carried out critical flow steady state experiments at high pressure,and to
