Abstract

Abstract

After the leakage of high temperature sodium metal in the heat pipe cooled reactor, it will react with air to produce combustion and even explosion, which will endanger the safety of the reactor core. The research on sodium leakage of heat pipe at high temperature is faced with some problems, such as few experiments and unknown phenomena. In this paper, simulation experiments of sodium heat pipe top leakage was carried out. 15 g of sodium was put into a stainless steel pipe and heated to 904.8℃. The degree of danger was judged by measuring the pressure and temperature changes during the experiment. The results showed that the leakage of the heat pipe produced yellow flame and explosion sound. 0.081 MPa pressure pulse was detected in the reaction chamber, and the maximum temperature rise of the reaction chamber was 192.1℃. The experimental results include experimental phenomena and leakage process analysis, which provides a basis for the subsequent design and safety assessment of heat pipe cooling reactor.
