Nuclear waste is radioactive waste, which can be classified into high-level radioactive waste and low-level radioactive waste depending on the intensity of radioactivity.

Ninety percent of nuclear waste comes from nuclear power plants, and other sources such as medical and agricultural research units also produce nuclear waste.

The spent nuclear fuel from nuclear power plants is highly radioactive waste, and the international practice is to adopt a three-stage treatment.

he spent nuclear fuel is first placed in the in-plant pool for adequate cooling, then moved into a dry (intermediate) storage facility for about 40 years. Finally, the spent nuclear fuel is moved to the final disposal site and permanently isolated from the human life circle.

At present, Nuclear Power No. 1 Plant, No. 2 Plant, and No. 3 Plant have encountered resistance in dry (medium) storage settings.

The final disposal site for permanent isolation was also opposed by the local government and the location was not yet clear.

Therefore, the spent nuclear fuel from nuclear power plants can currently only be stored in the in-plant pool.
