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

Abstract

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 flowing state and the distribution uniformity of the air in the testing part, and therefore the reference basis is provided for the reliability of the actual product performance. The system can be applied to testing of the nuclear power plant MSR.

Description

technical field [0001] The invention relates to the field of nuclear power tests, in particular to a large-flow gas fluid test system for a nuclear power plant MSR. Background technique [0002] The CAP1400 large pressurized water reactor nuclear power plant is a nuclear power plant independently designed by my country with independent intellectual property rights. At present, it is necessary to independently design an applicable steam-water separation reheater (MSR) according to the technical conditions of this type of nuclear power plant. Steam shell side pressure drop and distribution uniformity are important indicators affecting MSR performance. Because CAP1400 MSR is the first new MSR product independently designed in China, its structure is very different from previous nuclear power plant MSR products. Therefore, in order to completely guarantee product performance The reliability of the system needs to fully grasp the laws of these two performance indicators. [0003...

AI Technical Summary

Problems solved by technology

[0003] However, there is no test system for detecting the above two performance indicators in MSR in China. Although there are some test systems for MSR in foreign countries, there are still some shortcomings:

This method has the disadvantages of a large number of measuring points, a large number of conduits, a large space occupied by the U-shaped tube, a large reading error, and the inability to record data in real time;

[0005] (2) The test piece cannot directly observe the flow state and distribution uniformity of the gas inside, and can only be evaluated indirectly by measuring the pressure distribution, with low accuracy
