Description

technical field [0001] The invention relates to the field of security detection of nuclear power plants, in particular to a method for realizing a reaction kinetics detection device of a hydrogen elimination catalytic plate. Background technique [0002] After the Fukushima nuclear accident in Japan, the international and domestic attention to the risk of hydrogen explosion in the containment of nuclear power plants has increased, and it is required that dozens of passive hydrogen recombiners (PARs) must be distributed in the containment of the second-generation and third-generation nuclear power plants. , so as to quickly consume the hydrogen concentration in the accident state, thereby reducing or avoiding the danger of hydrogen explosion in design basis accidents and severe accidents. The core component of this passive hydrogen recombiner is a catalytic plate with a catalyst on its surface. Its working principle can be summarized as follows: [0003] In an accident state...
