It is understood that tungsten alloy shielding irrigation is more suitable for storing nuclear waste, compared to lead and concrete, and other shielding materials. tungsten materials are of advantages, such as environmental protection, non-toxicity ,non-radioactive, a high proportion, high hardness, strong rigidity, corrosion resistance, antioxidant, wear, and high-temperature resistance.
High-emission waste (spent fuel) refers to radioactive waste with high levels of concentrations of radionuclides that require special shielding during operation and transportation, such as 137 radon, 90 radon, plutonium, uranium, etc. Compared with low and medium, the high-rise is not only more radioactive, but also very hot, so it is very difficult to deal with.
The shielding tank containing high-level radioactive nuclear waste is suitable for production with tungsten alloy. Tungsten is an alloy material based on transition metal tungsten and with metal elements such as cobalt, nickel, iron, and copper as additives. Due to its high density, the shielding effect is much better than lead alloy material under the same thickness, with good thermodynamic and chemical properties, and no toxicity like metal lead, it is more in line with the requirements of future development.
