Problems solved by technology

[0002] Most of the existing technologies focus on the demonstration or teaching of hydrogen combustion or explosion. Although some technologies are related to nuclear power, their scale is small or the response environment is very different from that of a severe accident in a nuclear power plant. The distribution of temperature and pressure in the hydrogen deflagration process in space, so the existing technology is very insufficient for the study of hydrogen deflagration process in severe accidents of nuclear power plants

Abstract

The invention relates to the technical field of nuclear power serious accident research, and discloses a testing device for simulating a nuclear power station serious accident hydrogen deflagration environment, which comprises a pressure container and also comprises a gas main pipeline, gas branch pipelines and a heating module arranged in the pressure container; a hydrogen main inlet communicated with the gas main pipelines is formed in the bottom of the pressure container, and a hydrogen branch inlet, an oxygen inlet, an air inlet, a nitrogen inlet and a water vapor inlet which are respectively communicated with the corresponding gas branch pipelines are formed in the side wall of the pressure container; one or more layers of simulation environments are arranged in an inner cavity of the pressure container, and each layer of simulation environment is provided with a temperature measuring point, a pressure measuring point, a sample gas taking point, a water vapor concentration measuring point and an igniter; and the heating module corresponds to the position of the hydrogen main inlet. The device can simulate the hydrogen deflagration process of the large space of the containment vessel under the condition of serious accidents of the nuclear power station, signal changes such as temperature and pressure in the deflagration process are obtained, and basic data are provided for evolution of the hydrogen deflagration process.

Description

technical field [0001] The invention relates to the technical field of nuclear power serious accident research, and more specifically relates to a test device for simulating a hydrogen deflagration environment in a serious nuclear power plant accident. Background technique [0002] Most of the existing technologies focus on the demonstration or teaching of hydrogen combustion or explosion. Although some technologies are related to nuclear power, their scale is small or the response environment is very different from that of a severe accident in a nuclear power plant. The distribution of temperature and pressure in the hydrogen deflagration process in space, so the existing technology is very insufficient for the study of the hydrogen deflagration process in severe nuclear power plant accidents. Contents of the invention [0003] The purpose of the present invention is to aim at the technical problems existing in the prior art, to provide a test device for simulating the hy...
