IAEA Confirms Third Batch Of ALPS Treated Water Released Today Has Tritium Level Far Below Japan's Operational Limit

The tritium concentration in the third batch of diluted ALPS treated water, which Japan’s Tokyo Electric Power Company (TEPCO) started discharging today, is far below the country’s operational limit, International Atomic Energy Agency (IAEA) experts present at the site confirmed.

IAEA experts stationed at the IAEA Fukushima NPS Office took samples from the third batch of diluted water on 30 October, after it was prepared for discharge. Using Agency equipment, the IAEA’s independent on-site analysis confirmed that the tritium concentration in the diluted water that is being discharged is far below the operational limit of 1,500 becquerels per litre.

Japan is discharging the ALPS treated water from the Fukushima Daiichi Nuclear Power Station (FDNPS) in batches. The IAEA has confirmed that both previous batches - which started on August 24 and October 5 – also contained tritium concentrations far below operational limits.

Last week, the IAEA Task Force conducting the ongoing safety review of the water discharge said that the release was progressing as planned and without any technical concerns.

All reports on sampling, independent analysis and data evaluation will be available on the IAEA website (https://www.iaea.org/topics/response/fukushima-daiichi-nuclear-accident/fukushima-daiichi-alps-treated-water-discharge/tepco-data).
