Fukushima Daiichi Nuclear Power Station begins 23rd discharge of treated nuclear-contaminated water
At 11:29 on August 31, Fukushima Daiichi Nuclear Power Station began its fifth discharge of treated nuclear-contaminated water in fiscal year 2026 and the 23rd overall. The operation is scheduled to last 19 days, concluding on September 18, with an estimated discharge of approximately 7,800 tonnes of nuclear-contaminated water diluted with seawater, equivalent to the capacity of about 8 storage tanks. The total tritium content is estimated at approximately 1.2 trillion becquerels. The reactors of Units 1 to 3 at Fukushima Daiichi still contain nuclear fuel that melted and solidified during the accident, known as fuel debris. Groundwater and rainwater that come into contact with this fuel debris form contaminated water. Since the discharge of treated nuclear-contaminated water began in August 2023, Fukushima Daiichi has cumulatively released approximately 173,000 tonnes, equivalent to about 173 storage tanks' capacity.

Three Years Since Japan Began Discharging Nuclear-Contaminated Water: Over 170,000 Tons Released Across 22 Rounds
Since August 24, 2023, Japan has been discharging nuclear-contaminated water from the Fukushima Daiichi Nuclear Power Station into the Pacific Ocean. As of August 24, 2026, Japan has completed a total of 22 rounds of discharge, with a cumulative volume of approximately 173,000 tons. It is understood that the volume of water stored in on-site tanks has decreased by about 7% compared to before the discharge began. Tokyo Electric Power Company plans to increase the discharge volume of nuclear-contaminated water starting from the current fiscal year and has set a target to complete the decommissioning of the nuclear power plant by 2051. ...
