Independent sampling and analysis conducted by the International Atomic Energy Agency (IAEA) have confirmed that the tritium concentration in the 13th batch of ALPS-treated water, which Tokyo Electric Power Company (TEPCO)?began discharging today from the Fukushima Daiichi Nuclear Power Station (FDNPS), is far below Japan’s operational limit.

As part of its ongoing safety review, the IAEA collected and analyzed samples onsite of the diluted water that was being prepared for discharge as part of this latest batch. The results confirmed that the tritium concentration is far below the operational limit of 1,500 becquerels per litre and is in line with international safety standards.

Japan is releasing the ALPS-treated water in a series of batches over the next decades, following the start of the discharge in August 2023. The treated water is diluted with seawater prior to discharge. Of the 93.500 cubic meters of water already released in the first 12 batches, the IAEA confirmed that the tritium concentrations were far below the international safety standards and operational limits.

In a comprehensive report issued on 4 July 2023 before the discharge began, the IAEA’s safety review found that Japan’s plan for handling the treated water was consistent with international safety standards and that the release as planned would have a negligible radiological impact to people and the environment.

Reports on sampling, independent analysis, data evaluation, as well as timeline, are available on the?IAEA website.
