Embodiment Construction

[0031] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0032] see figure 1 , a T-tube entrainment test system based on the reactor's fourth-stage decompression system of the present invention, comprising: a deionized water preparation system 1, a replenishment pump 2, a heating water tank 3, a filter 4, a high-temperature pump 5, a mass flow meter 6, Preheating section 7, boiler 8, cylinder 9, visualization test section 10, weighing water tank 11, weighing sensor 12 and return water pipeline 13.

[0033] The deionized water preparation system 1 is connected to the heating water tank 3 through the supplementary water pump 2. After being heated by the heating water tank 3, the liquid phase enters the preheating section 7 through the filter 4 and the high temperature pump 5, and then is sent to the test section 10; The water flowing out of the water preparation system 1 flows into the boiler 8 through a...

Abstract

The invention discloses a T-shaped tube entrainment test system and method based on a fourth-level automatic depressurization system of a nuclear power plant reactor. The system comprises a heating water tank, a high-temperature pump, a preheating section, a boiler, a visualization test section and a weighing water tank, wherein the heating water tank, the high-temperature pump and the preheating section are sequentially connected, and an outlet of the preheating section is connected with a liquid phase inlet of the visualization test section; a steam outlet of the boiler is connected with a gas phase inlet of the visualization test section; the visualization test section is a T-shaped tube comprising a horizontal main tube and a vertical branch tube; the branch tube of the visualization test section is connected with the weighing water tank. The system can be used for performing an entrainment test adopting steam / water as working media, and the condition in the reactor is reflected more really. With the adoption of the system, visualization research of a key experiment part is realized, and conditions are provided for further understanding and research of experiment phenomena. The test system can be applied to the entrainment test capable of adjusting double-end gas intake, the test more meets the real condition, and the simulated situation is more complicated.

Description

technical field [0001] The invention relates to the field of steam-water two-phase flow thermal-hydraulic test research, in particular to a T-tube entrainment test system and method based on the 4th-level automatic depressurization system (ADS-4) of a nuclear power plant reactor. Background technique [0002] In AP1000, the automatic depressurization system (Automatic Depressurization System, ADS) is divided into four stages, and its function is to reduce the pressure of the reactor coolant system during the accident in a controlled manner for safety injection. Among them, there are two sets of ADS-1 / 2 / 3 step-down pipelines, which are connected in parallel to form two groups and connected to the top of the regulator, and the outlet is connected to the sprinkler in the IRWsT through the same step-down pipeline; The pressure system pipelines are respectively connected to the top of the heat pipe section in the two loops of the reactor, and the outlet is directly connected to t...
