Embodiment Construction

[0060] A method for measuring aerosol concentration and behavior under test conditions, the method specifically comprises the steps of:

[0061] Step 1. Preheat the aerosol measurement system;

[0062] Step 1.1, preheating the steam generator connected to the test container;

[0063] The steam generator is a stainless steel container with a heater installed inside, which can generate high-temperature and high-pressure steam, and transport it to the lower part of the water jacket area on the side wall of the test container. The water supply tank is connected with the steam generator through a water pump, and the steam is generated through the water supply tank The generator supplies deionized water; the steam generator is preheated to 150°C to 200°C through the heater;

[0064] Step 1.2, start the water temperature control system connected to the test vessel, and control the temperature of the test vessel;

[0065] The side wall of the aerosol test container is a sandwich str...

Abstract

The invention relates to the technical field of aerosol test in a containment vessel, and specifically discloses a method for measuring aerosol concentration and behavior under test conditions. The method includes: 1. Preheating the aerosol measurement system; 2. Transporting the aerosol to the test container and depositing it; 3. Using the aerosol measurement system connected to the test container to measure the aerosol; 4. Conducting Aerosol resuspension and re-entrainment measurement; 5. Perform aerosol measurement; 6. After completing the aerosol measurement, perform pressure release of the test container and emptying of exhaust gas and waste liquid. This measurement method can systematically and comprehensively carry out test model research on the aerosol migration behavior in the passive containment of the third-generation nuclear power plant, and use the test simulation of the real aerosol environment to facilitate the aerosol behavior test under severe accident conditions.

Description

technical field [0001] The invention belongs to the technical field of aerosol test in a containment vessel, and in particular relates to a method for measuring aerosol concentration and behavior under test conditions. Background technique [0002] In traditional second-generation PWRs, dry-sealed containment vessels are generally used. The containment vessel is made of reinforced concrete, and a containment spray system is specially set up to reduce the pressure and temperature inside the containment vessel under accident conditions. The passive containment cooling system is installed in the third-generation large-scale advanced pressurized water reactor AP1000. The system consists of a water storage tank integrated with the containment shielding structure, and the water is delivered from the water tank to the containment shell through the flow distribution device. The piping of the body, as well as related instruments, piping and valves. [0003] In the case of severe ac...
