6th June 2023 – (Tokyo) Japan has begun sending seawater into an underwater tunnel built to release nuclear-contaminated water into the ocean from the Fukushima Daiichi nuclear power plant, according to local media reports. Tokyo Electric Power Company (TEPCO), the plant’s operator, said the process began on Monday afternoon and is expected to fill the tunnel with about 6,000 tons of seawater by Tuesday noon.
Once filled, the tunnel will guide the contaminated water from the plant to a point about 1 kilometre offshore. Japan’s plan to discharge radioactive water into the ocean has faced opposition from home and abroad, but the release system is almost complete and construction work is expected to be finished by the end of the month. The Fukushima Daiichi nuclear power plant suffered a level-7 nuclear accident in 2011, and has generated a large amount of water tainted with radioactive substances that is stored in about 1,000 storage tanks.
