IAEA: Transparency key to public confidence on Fukushima water release

The International Atomic Energy Agency (IAEA) has confirmed that the latest discharge of treated water from Japan's Fukushima Daiichi Nuclear Power Station meets international safety standards. Tokyo Electric Power Company (TEPCO) began releasing its 19th batch of water on June 10, 2026.

Independent analysis conducted by the IAEA shows that tritium levels in the discharged water remain significantly below Japan's operational limit of 1,500 becquerels per litre. The agency's ongoing assessment indicates the process aligns with global safety benchmarks. The treated water is released into the Pacific Ocean through a one-kilometre underwater tunnel, a method designed to ensure controlled and diluted discharge.

Japan initiated the release of ALPS-treated water in August 2023 as part of a long-term strategy to manage contaminated water accumulated after the 2011 nuclear disaster. To date, approximately 140,500 cubic metres of treated water have been discharged. All previous batches have been verified by the IAEA as meeting safety standards. The Advanced Liquid Processing System (ALPS) removes most radioactive elements, leaving only trace amounts of tritium.

The Fukushima water release program continues to face international scrutiny, with neighbouring countries and stakeholders monitoring environmental and health impacts. The IAEA maintains a continuous presence and oversight role, providing independent verification to ensure transparency and adherence to safety guidelines. Experts emphasize that sustained monitoring and transparent reporting are critical as Japan proceeds with its multi-year discharge plan.
