Deep geological disposal is the most common. But it requires high geological environment. For example, no water seepage, no earthquake, no nuclear pollution within 10 thousand years, how to safely transport nuclear waste to the designated storage place. At present, the major nuclear countries in the world have spent fuel treatment devices, including France, the United States, Britain, Russia and Japan, which basically adopt deep geological storage.
China National Nuclear Corporation (CNNC) is responsible for handling nuclear waste. According to the company's website, on September 1 day, 20265438, China's first "glass curing facility for high-level radioactive waste liquid" was officially put into operation in Guangyuan, Sichuan, which marked that China achieved a breakthrough in the treatment capacity of high-level radioactive waste liquid and became one of the few countries in the world with glass curing technology for high-level radioactive waste liquid.
Sources of nuclear waste water
Nuclear sewage mainly comes from the operation of nuclear reactors, but it also includes by-products and fission products of nuclear fuel. Next, we will introduce the process of producing nuclear sewage in detail. Nuclear sewage refers to the waste water containing radioactive substances produced in nuclear energy-related activities.
Nuclear power plants are the main source of nuclear wastewater. Nuclear power plants generate electricity through nuclear reaction, but some radioactive wastewater will be produced during the nuclear reaction. These nuclear waste waters mainly include cooling water, deteriorated water from light water reactors and radioactive waste liquid.
Nuclear waste water may be produced in the process of nuclear experiment and research, including waste water produced by cooling aqueous solution of experimental equipment. The treatment and discharge of nuclear wastewater is a challenge with technical and environmental risks.
