Strengthening the safety defense line of urban radioactive waste storage areas: The key mission of perimeter fence anti-corrosion technology is to ensure the proper disposal of urban radioactive waste in the vast system of urban operation. As a key place for storing these special wastes, the storage areas must not be compromised in terms of safety. The perimeter fence of the storage area and its anti-corrosion technology play a crucial role in safeguarding the safety of the storage area and maintaining urban public safety. 

Urban radioactive waste, due to its radioactivity, can cause incalculable harm to human health and the ecological environment once leaked or improperly exposed. As a centralized storage area for such hazardous waste, the warehouse area bears a huge responsibility for safety. The perimeter fence, as the first physical line of defense in the storage area, has extraordinary significance. It clearly defines the scope of the storage area, physically blocking the unauthorized entry of unrelated personnel and animals, and avoiding safety accidents caused by accidental contact with radioactive waste. 

However, the environment in which the storage area is located is often complex and ever-changing, which poses a severe challenge to the durability of the perimeter fence. Whether it is the scorching sun, the erosion of rainwater, or the corrosion of chemicals, the performance of the fence may gradually weaken. At this point, anti-corrosion technology has become a key support for the long-term stable functioning of perimeter fences. 

The advanced anti-corrosion technology is first reflected in the selection of materials. Metal materials with good corrosion resistance, such as stainless steel, are usually selected. The elements it contains, such as chromium and nickel, can form a dense oxide film on the metal surface, effectively resisting the erosion of external substances. For some storage areas that require extremely high corrosion resistance, specially treated alloy materials will be used to further enhance their corrosion resistance.

 In addition to high-quality materials, surface treatment technology is also a key step in anti-corrosion. The hot-dip galvanizing process is a common method of immersing fence components in molten zinc solution to cover their surface with a layer of zinc. The zinc layer can not only isolate the contact between air and moisture and the metal body, but also, when the zinc layer is partially damaged, it can be preferentially corroded through its sacrificial anode protection effect, thereby protecting the main structure of the fence. 

In addition, coating protection is also an indispensable means. High performance anti-corrosion coatings, such as epoxy resin coatings, polyurethane coatings, etc., can form a tough protective film on the surface of fences. These coatings have good adhesion, chemical corrosion resistance, and weather resistance, which can effectively block external factors such as ultraviolet radiation and acid rain from damaging the fence. 

The anti-corrosion process of the perimeter fence of the storage area is not a simple technical operation, but a key guarantee for maintaining the safety of the urban radioactive waste storage area. It ensures that the perimeter fence stands firm in complex environments for a long time, continuously playing its role in blocking and protecting, building a strong barrier for the safe storage of urban radioactive waste, safeguarding the public safety and ecological environment of the city, and allowing the city to operate smoothly on a safe track.
