Beijing, September 12 (Reporter Feng Hua) Reporter learned from the State Atomic Energy Agency: On the 11th, the first high-level radioactive waste glass curing facility in China was officially put into operation in Guangyuan, Sichuan. This is a landmark project at the back end of China's nuclear industry chain, and its entry into operation marks that China has achieved a breakthrough in zero high waste liquid treatment capacity, becoming one of the few countries in the world with high waste liquid glass curing technology.

Radioactive waste treatment is the last link in the safe use of nuclear energy, of which the most difficult and technical content is the treatment of high-level radioactive waste liquid. Radioactive waste glass curing is at a temperature of 1100 degrees Celsius or higher, the radioactive waste liquid and glass raw materials are mixed and melted, and the glass body is formed after cooling. Due to the low leaching rate and high strength of the vitreous body, it can effectively contain radioactive materials and form a stable form, which is currently the most advanced waste liquid treatment method in the world.

After the facility is put into operation, it is expected that hundreds of cubic meters of high-level waste liquid can be safely disposed of every year, and the vitreous bodies produced by the treatment will be buried in the disposal depot hundreds of meters deep underground, achieving the goal of isolating radioactive materials from the biosphere.

Liu Yongde, chief engineer of the State Atomic Energy Agency, said that in the next step, the IAEA will further optimize the layout of the nuclear environmental protection industry, continue to improve the nuclear environmental protection capability system, and accelerate the process of radioactive waste treatment.
