Tokyo Electric Power Company (TEPCO) announced on December 22 that the 17th discharge of contaminated water from the Fukushima Daiichi Nuclear Power Plant into the sea had concluded that day.
Ignoring strong international criticism and opposition, Japan unilaterally and forcibly initiated the discharge of contaminated water from the Fukushima Daiichi Nuclear Power Plant into the sea in August 2023. With the completion of the 17th discharge, the cumulative amount of contaminated water discharged from the Fukushima Daiichi plant has reached approximately 133,000 tons.
Data released by TEPCO on the 22nd shows that the 17th discharge began on December 4th. Discharge was temporarily suspended due to an earthquake that occurred in the sea east of Aomori Prefecture on the evening of December 8th, but resumed on December 9th. A total of 7,833 tons of contaminated water, containing approximately 2.4 trillion becquerels of radioactive tritium, was discharged.
Data shows that TEPCO plans to conduct seven more discharges in fiscal year 2025 (April of 2025 to March of the following year), with a total discharge of approximately 54,600 tons. The final discharge in fiscal year 2025 will be conducted in March 2026.
