Embodiment 1

[0062] When doing science popularization manually:

[0063] 1) System initialization, primary circuit leakage valve 5, colored flue gas filling valve 6, air filling valve 7, and containment venting valve 8 are all in the disconnected state; fuel cladding 2 is illuminated; "the first safety barrier is valid" indication Lamp 12 emits light; speaker 18 voice prompts: "The reactor is operating normally, and the first safety barrier is effective."

[0064] 2) Check the "manual / automatic" button 16 to confirm that the system is running in manual mode.

[0065] 3) Press the "accident development" button 15 and release it, indicating that an accident begins to develop. The button is a self-resetting button, which automatically returns to the pop-up state.

[0066] 4) The indicator light 12 of "the first safety barrier is effective" is off; the colored smoke filling valve 6 is turned on, and the colored smoke enters the pressure boundary 3 of the primary circuit. As time goes on, th...

[0074] When doing science popularization automatically:

[0075] 1) System initialization, primary circuit leakage valve 5, colored flue gas filling valve 6, air filling valve 7, and containment venting valve 8 are all in the disconnected state; fuel cladding 2 is illuminated; "the first safety barrier is valid" indication Lamp 12 emits light; speaker 18 voice prompts: "The reactor is operating normally, and the first safety barrier is effective."

[0076] 2) Check the "manual / automatic" button 16 to confirm that the system is running in automatic mode.

[0077] 3) The system waits for a period of time (set in advance), and the accident begins to develop.

[0078] 4) The indicator light 12 of "the first safety barrier is effective" is off; the colored smoke filling valve 6 is turned on, and the colored smoke enters the pressure boundary 3 of the primary circuit. As time goes on, the smoke concentration in the pressure boundary 3 of the primary circuit is getting higher and h...

Abstract

The invention provides a science popularization teaching aid and a science popularization method about the safety of nuclear power station reactors. The science popularization teaching aid comprises a sealed containment vessel, a loop pressure boundary arranged in the containment vessel in a sealed manner, and a fuel jacket arranged in the loop pressure boundary in a sealed manner, the science popularization teaching aid also comprises a containment vessel evacuation valve, a colored smoke generator, a colored smoke filling valve arranged on a pipeline between the colored smoke generator and the loop pressure boundary, and a loop leakage valve arranged on a pipeline between the loop pressure boundary and the containment vessel, the containment vessel discharges internal gas via the containment vessel evacuation valve, the containment vessel and the loop pressure boundary are at least partly transparent, and light bands are arranged in the fuel jacket. According to the above science popularization teaching aid, colored gas is employed to simulate the diffusion process of radioactive materials during accidents in a nuclear power station, and the effect of three safety barriers of the nuclear power station is visually and vividly displayed to the public.

Description

technical field [0001] The invention relates to popular science teaching aids, in particular to a science popularization teaching aid and a science popularization method about the safety of nuclear power plant reactors. Background technique [0002] Due to the ignorance of the safety of nuclear power plants, the public generally has a sense of fear of nuclear power plants. Introducing the basic knowledge of nuclear power to the public, promoting nuclear safety culture, and eliminating the public's "nuclear fear" psychology is an important task for my country's nuclear power industry, and it is also the responsibility and obligation of every nuclear power practitioner. [0003] In fact, to prevent radioactive fission products from escaping, nuclear power plants have three safety barriers (sometimes separating the fuel pellets from the fuel cladding, called four safety barriers): [0004] The first barrier is "fuel pellets and fuel cladding". The radioactive substances produ...
