Discussion of Nuclear Hydrogen Ignition Equipment Selection

In order to eliminate concentration hydrogen in the containment under the severe accidents of nuclear power plants, it is necessary to add Hydrogen Ignition Equipment. The paper analyzes the main theory of the hydrogen igniter and passive autocatalytic recombiner which are used mostly, and how to select the nuclear hydrogen ignition equipment, based on the improvement of adding the nuclear hydrogen recombiner of a nuclear plant. The improvement of the nuclear plant shows that it is very important to select the most suitable hydrogen ignition equipment for nuclear plants and society.
