TEPCO discharges 172,700 tons of treated Fukushima water over three years

Tokyo Electric Power Company Holdings Inc. reported that 172,700 tons of treated radioactive water have been released from the Fukushima plant over three years, spread across 22 discharge events. The volume stored in tanks dropped 7.6 percent to around 1.24 million tons, allowing 17 empty tanks to be removed. The International Atomic Energy Agency, together with Japanese authorities, continues to monitor the process and has found no abnormal tritium concentrations in surrounding sea or marine products.

The company plans to complete all releases by 2051, coinciding with the plant’s overall decommissioning schedule. China imposed a blanket ban on Japanese seafood imports when the releases began and has kept restrictions despite a partial lift announcement, while Russia and other regions also maintain limits. TEPCO has compensated affected businesses, paying roughly 92.8 billion yen for losses such as halted scallop and sea cucumber exports. Chief decommissioning officer Akira Ono affirmed the safety of the releases and pledged ongoing transparent information and compensation.
