Nuclear wastewater refers to wastewater generated from the use of nuclear energy, including wastewater used to cool nuclear reactors and wastewater used to treat radioactive waste. This wastewater contains different levels of radioactive material and must be treated and purified before it can be safely discharged or reused.
Nuclear contaminated water refers to the water environment contaminated by radioactive substances, such as nuclear leakage, nuclear accident, nuclear explosion caused by the environment with relatively high concentration of radioactive substances in the water. Nuclear wastewater refers to the waste water produced in the production process, its production is inevitable, but also controllable and manageable, which means that we can purify it through appropriate treatment methods, and reasonable treatment of these waste water.

On August 22, 2023, the Japanese government announced that it would start the discharge of Fukushima nuclear contaminated water into the sea on August 24. The release of contaminated water from Japan will continue for at least 30 years and will affect the entire Pacific Ocean and even global waters. Due to the large time span and wide scope of impact, the Japanese government's decision once announced has caused many objections.
On August 24, 2023, Tokyo Electric Power Company said it had taken samples of nuclear-contaminated water to be discharged into the ocean, and the concentration of tritium was "up to standard". If the weather conditions allow, Japan's nuclear contaminated water will be discharged into the ocean on the afternoon of the 24th local time, and the discharge work will start at 13 o 'clock. According to the plan, the drainage time will last at least 30 years.
At 13:00 local time on August 24, 2023, Japan's Fukushima First nuclear power plant started to discharge nuclear contaminated water into the sea.

On August 26, 2023, according to Japan's TBS television station, TEPCO admitted that about 66% of the nuclear contaminated water in the current storage tank contains excessive radioactive substances. When asked when the nuclear contaminated water can be completely discharged, the head of the crisis public relations of Tepco said that when the nuclear contaminated water can be completely discharged, Tepco does not have any specific plans at present.
August 28, 2023, Japan's Fukushima nuclear contaminated water into the sea has entered the fifth day. According to data released by Tokyo Electric Power Company, as of midnight local time yesterday (27), the total amount of nuclear contaminated water discharge has reached about 1,095 tons.
