Where is the nuclear waste water discharge point in Japan?

Japan's nuclear wastewater discharge point is located in the deep-sea injection well of Fukushima nuclear power plant.

Fukushima nuclear power plant is one of the largest nuclear power plants in Japan, located in Fukushima Prefecture in the northeast of Japan. On 20 1 1 March11day, the Fukushima nuclear power plant was seriously damaged in the Great East Japan Earthquake, resulting in a large number of radioactive materials being released into the environment. In order to treat these radioactive substances, the Japanese government has taken various measures, including treating the wastewater containing radioactive substances by physical and chemical means such as filtration, precipitation and neutralization, and then discharging it into the sea.

According to the plan of the Japanese government and Tokyo Electric Power Company, the nuclear wastewater will be transported to the deep-sea injection well about 1 km away from the Fukushima nuclear power plant through specially built pipelines. The wastewater is injected into the underground rock about 50 meters below the seabed through the injection well. In short, although the Japanese government chose to discharge nuclear wastewater into deep-sea injection wells, this decision is still controversial and controversial internationally.

The difference between nuclear waste water and nuclear sewage;

Nuclear waste water and nuclear polluted water are two different concepts. Nuclear waste water refers to waste water generated by nuclear energy, including waste water for cooling nuclear reactors and waste water for treating radioactive waste. These wastewater contain different levels of radioactive substances and must be treated and purified before it can be safely discharged or reused. Nuclear polluted water refers to the water environment polluted by radioactive substances, such as water with high concentration of radioactive substances produced by nuclear leakage, nuclear accident and nuclear explosion.

Although nuclear waste water and nuclear polluted water have different meanings, the management and supervision of the government and society are very important for protecting the environment and human health. For nuclear waste water, comprehensive monitoring and purification must be carried out to ensure that its discharge meets national standards and regulations. For the nuclear polluted water body, stricter measures should be taken to urgently seal the polluted area to avoid the spread of radioactive substances and personal injury, and at the same time, the follow-up environmental restoration work should be actively implemented.
