Japanese media quoted a relevant person from the Japanese government on the 24th local time and reported that the Japanese government and Tokyo Electric Power Company have basically finalized the construction of a route from the Fukushima Daiichi Nuclear Power Plant to the offshore waters regarding the discharge of nuclear polluted water from the Fukushima Daiichi Nuclear Power Plant into the sea. In the submarine tunnel, nuclear contaminated water is diluted by seawater and then drained into the sea 1 kilometer from the coast through the tunnel.
It is understood that the Japanese government and Tokyo Electric Power Company have been studying the method of discharging pollutants into the sea on the offshore discharge plan and the direct discharge into the sea from the outlets of the No. 5 and No. 6 generating units.
After comprehensive consideration, it was finally decided to formulate a specific plan for the offshore emission plan.
Tokyo Electric Power Company will submit an implementation plan including equipment design and operating procedures to the Japan Atomic Power Regulatory Commission in the near future, and wait for approval.
At present, the nuclear contaminated water stored in the storage tank of the Fukushima Daiichi Nuclear Power Plant has reached approximately 1.27 million cubic meters.
The concentration of radioactive substances in 70% of the water exceeds Japan's national emission standards, and a multi-nuclide removal device is required to reduce the concentration.
However, because the radioactive substance tritium cannot be removed by current technical means, Japan plans to use seawater to dilute the treated nuclear contaminated water.
In April of this year, the Japanese government formally decided to discharge nuclear contaminated water from the Fukushima Daiichi Nuclear Power Plant into the sea, which caused many dissatisfaction.
