Harm of nuclear sewage

The hazards of nuclear sewage are mainly marine environmental pollution, food safety problems and economic impact.

1, marine environmental pollution

The discharge of nuclear sewage from Japan will cause serious pollution to the ecological environment in the surrounding waters, and these pollutants may spread to China's waters through ocean currents, which will have an impact on China's marine ecological environment.

2. Food safety issues

The discharge of Japanese nuclear sewage may lead to the pollution of aquatic organisms in the surrounding waters, and may enter the China market after being caught and processed, posing a threat to food safety in China.

3. Economic impact

If China's marine ecological environment and food safety are affected by Japanese nuclear sewage discharge, it will have a serious impact on China's fisheries, tourism and other industries and bring losses to China's economy. Therefore, the harm of Japanese nuclear sewage discharge to China is very serious, and effective measures should be taken to prevent and treat it.

Sources of nuclear waste water in Japan;

After the 20021,10 Fukushima earthquake, the Japanese government officially decided to discharge the nuclear wastewater from the Fukushima Daiichi nuclear power plant into the sea, which was strongly opposed by many countries, including China. These nuclear wastes are a large amount of sewage produced by introducing seawater for cooling to avoid the meltdown of the reactor core after the earthquake. The total capacity of all water storage facilities is 6.5438+0.37 million tons, which is expected to reach its peak in autumn 2022. The Japanese government said that a large amount of radioactive materials had been removed with special equipment, but tritium could not be removed.

There are three main sources of nuclear wastewater in Japan: the original coolant of the reactor, the newly injected water for cooling the reactor core after the accident, and a large amount of groundwater infiltrating into the reactor. The nuclear reactor, the core component of the nuclear power plant, was damaged in the explosion accident that year, resulting in the leakage of 2 10 tons of cooling water inside.
