Abstract: High level liquid waste generates hydrogen gas during storage. If the hydrogen in the high-level liquid waste tank is not discharged or diluted in time, and when the concentration of hydrogen in the mixed gas reaches the explosion threshold, an explosion will possibly occur. In this paper, the explosion pressure and wall temperature of hydrogen in the high-level liquid waste tank are studied by using the experimental device. The test results show that the maximum explosion over-pressure is about 0.596 5 MPa, and the maximum wall temperature is about 110 ℃ when the hydrogen concentration is 30%(vol), and the ignition position is near the top center of the tank.

Key words: high level liquid waste tank, hydrogen, explosion, accident, test
