High-flow air fluid testing system for nuclear power plant MSR

The invention relates to a high-flow air fluid testing system for a nuclear power plant MSR. The high-flow air fluid testing system comprises a testing part, a fan system, a pipeline system and a measuring system, wherein the testing part is used for simulating the MSR shell pass, the fan system provides flowing air for the testing part for simulating steam, the pipeline system is connected with the fan system and the testing part, and the measuring system comprises a smoke generator installed on the pipeline system and a measuring device for detecting the working condition of the testing part. The testing part is used for simulating the MSR shell pass, the fan system is used for generating the compressed air for simulating the steam so as to provide simulated air for the testing part, the measuring device in the measuring system can measure the pressure drop of a tester, smoke particles generated by a smoke generator enter the testing part along with the compressed air, the measuring system detects the flowi
