Experiment system for simulating nuclear containment benchmark accident condition and realizing method of experiment system

Abstract

The invention discloses an experiment system for simulating a nuclear containment benchmark accident condition and a realizing method of the experiment system, and solves the problem that the nuclear containment benchmark accident condition cannot be simulated comprehensively in the prior art. The experiment system comprises an experiment container, a first pressure sensor, a data acquisition system, an exhaust pipeline, an air supply system, a hydrogen supply system and at least four sampling pipelines, wherein the experiment container is used for loading a complete machine of a passive hydrogen recombiner; the first pressure sensor is arranged in the experiment container and used for detecting inner pressure of the experiment container; the exhaust pipeline, the air supply system, the hydrogen supply system and at least four sampling pipelines are connected with the experiment container; and the experiment container is connected with the data acquisition system through a multi-point thermoelectric couple. According to the experiment system for simulating the nuclear containment benchmark accident condition and the realizing method of the experiment system, the structural design is reasonable, the nuclear containment benchmark accident condition can be simulated really and comprehensively, the hydrogen elimination performance of the passive hydrogen recombiner is tested, a test result is very close to the actual condition, and accordingly, a terrific reference standard is further provided for study and design of the recombiner.

Description

technical field [0001] The invention relates to an experimental system related to nuclear power hydrogen safety equipment, in particular to an experimental system for simulating a reference accident working condition of a nuclear power containment vessel and a realization method thereof. Background technique [0002] After the Fukushima nuclear accident in Japan, more and more attention has been paid to the hydrogen risk control in the containment of nuclear power plants, and the requirements for hydrogen safety equipment are getting higher and higher. In particular, passive hydrogen recombiners (PARs), which are the main means of hydrogen elimination, must be evaluated for their operational performance under accident conditions. As a standard performance assessment of the hydrogen recombiner, its hydrogen elimination performance under design basis accident conditions needs to be assessed. The design basis accident conditions are as follows: the initial temperature is norma...

AI Technical Summary

Problems solved by technology

Although there are researches in this area in China, due to technical limitations, the simulation test of the design basis accident conditions of the recombiner can only be used for laboratory research, and the passive hydrogen recombiner cannot be tested, so It is still in the stage of theoretical analysis, and the level of the recombiner studied is relatively low, which cannot fully reflect the real hydrogen elimination performance of the passive hydrogen recombiner under the benchmark accident conditions, so it is difficult to meet the needs of the current actual working conditions
