TEPCO completes third year of Fukushima water releases, totaling 172,729 tons

Tokyo Electric Power Company Holdings Inc. (TEPCO) has completed three years of releasing treated radioactive water from the Fukushima No. 1 nuclear plant into the sea, discharging about 172,729 metric tons in 22 operations. Storage has declined only about 7%, from approximately 1.33 million tons before releases began on Aug. 24, 2023, to nearly 1.24 million tons. Groundwater and rainwater still enter the reactor buildings, generating an average of 60 tons of newly contaminated water each day. TEPCO purifies the water through the Advanced Liquid Processing System, dilutes it with seawater and releases it under monitoring by the International Atomic Energy Agency (IAEA), the Japanese government and TEPCO. The IAEA said in June that the process was consistent with international nuclear safety standards, and no abnormal tritium levels have been detected in nearby waters or seafood. TEPCO plans eight release operations this year and aims to complete discharges alongside decommissioning by 2051, but the target faces uncertainty because melted fuel-debris removal is not expected to begin in earnest until 2037 or later. Only 17 of 1,046 storage tanks have been dismantled. China, Russia, Hong Kong and South Korea continue to impose import restrictions of varying scope, depressing prices for sea cucumbers and abalones even as scallop exports recover through alternative markets. Fukushima coastal fishery income reached 4.37 billion yen, about $27.4 million, last year, roughly half its pre-2011 earthquake and nuclear accident level. TEPCO reported compensation payments of either 96.7 billion yen ($607.8 million) or about 92.8 billion yen ($585 million), depending on the cited company update, across roughly 1,100 claims as of Aug. 5.
