IAEA confirms 24th ALPS water batch below Japan's 1,500 Bq/L tritium limit
TEPCO began discharging the batch from Fukushima Daiichi on October 5; about 180,600 cubic metres have been released in batches since August 2023.
Key facts
- IAEA tested samples from the batch at the site before release into the ocean
- First 23 batches also confirmed far below Japan's operational limits
- July 2023 IAEA report found negligible radiological impact on people and the environment
- IAEA maintains a presence at the site and monitors the discharge process
The IAEA said it independently tested samples from the 24th batch of ALPS-treated water before Tokyo Electric Power Company discharged it from the Fukushima Daiichi Nuclear Power Station on October 5. Analysis at the site showed tritium levels far below Japan's operational limit of 1,500 becquerels per litre and meeting international safety standards.
Japan has discharged roughly 180,600 cubic metres of ALPS-treated water in batches since August 2023. The IAEA has confirmed that tritium levels in the first 23 batches were far below the operational limits set by Japan.
In a comprehensive report issued in July 2023, the IAEA concluded that Japan's approach to the discharge of ALPS-treated water is consistent with relevant international safety standards and that the release, as planned and assessed, would have a negligible radiological impact on people and the environment. The agency maintains a presence at the site and carries out monitoring and verification activities throughout the discharge process.
