Fukushima water storage falls just 7% after 172,729-ton discharge

Three years after Tokyo Electric Power Company Holdings began releasing treated water from the Fukushima No. 1 nuclear power plant, about 172,729 metric tons have been discharged in 22 operations. Yet storage has declined only about 7%, from approximately 1.33 million tons before the first release in August 2023 to nearly 1.24 million tons today. Groundwater and rainwater continue entering reactor buildings, producing 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 a plan the International Atomic Energy Agency said in June was consistent with international nuclear safety standards. The utility plans eight operations this year and will begin secondary treatment for water that fails release standards, but it has not disclosed the scale of future discharges or a concrete plan to reduce the overall volume. Removing melted nuclear fuel debris, viewed as fundamental to solving the problem, is not expected to begin in earnest until 2037 or later, raising doubts about the target of completing releases and decommissioning by 2051. Seafood trade remains disrupted. China, Russia, Hong Kong and South Korea continue to impose restrictions of varying scope, and prices for sea cucumbers and abalones have fallen sharply even as scallop exports recover through alternative markets. Fukushima coastal fishery income reached 4.37 billion yen, or about $27.4 million, last year, roughly half its pre-2011 earthquake and nuclear accident level. Tepco had paid 96.7 billion yen, about $607.8 million, on roughly 1,100 claims as of Aug. 5, but processors say the claims process is difficult. The contrasting performance of scallops and sea cucumbers suggests that import restrictions, rather than measurable safety concerns, are driving the industry's uneven recovery.
