TEPCO ends 2nd round of FY 2026 treated water release
Tokyo Electric Power Company Holdings Inc. said Saturday that it has completed the second round of the fiscal 2026 treated water release into the Pacific Ocean from its crippled Fukushima No. 1 nuclear power plant, a day later than planned, Jiji Press reports.
In the just ended round, about 7,900 tons of water containing small amounts of radioactive tritium was discharged about 1 kilometer off the 2011 meltdown-hit coastal power plant in Fukushima Prefecture, northeastern Japan, through an undersea tunnel after being diluted with large amounts of seawater.
In the fiscal year that began in April, TEPCO plans to release a total of about 62,400 tons of treated water in eight rounds.
The latest discharge, which began on June 1, was temporarily halted on June 10 and 13 after alarms indicating abnormalities in the process sounded, causing delays to the schedule.
Following the first alarm activation, TEPCO identified a tank outlet valve as the cause and resumed operations the following day after replacing it.
Earlier, Qazinform reported Tokyo Electric Power Company Holdings (TEPCO) had started removing nuclear fuel from the spent fuel pool of the No. 2 reactor at the Fukushima Daiichi nuclear power plant, marking a critical step in the site’s long-term decommissioning.
