Visit of IAEA officials and international experts for a review on the discharge of ALPS treated water from TEPCO’s Fukushima Daiichi Nuclear Power Station into the Sea
From May 26 to 30, the IAEA Task Force consisting of the IAEA officials and international experts will visit Japan for the review on the discharge of ALPS treated water from TEPCO’s Fukushima Daiichi Nuclear Power Station (FDNPS) into the sea.
This time, the review will focus on the monitoring programme on ALPS treated water and its results.
The Government of Japan will continue to provide necessary information to the IAEA. The Government of Japan also remains committed to making efforts to foster better understanding both domestically and internationally regarding the handling of ALPS treated water.

(Reference2) ALPS treated water
ALPS treated water is water that contained radioactive substances from inside the buildings of TEPCO’s FDNPS, and has been purified and treated through multiple treatment facilities, including ALPS (Advanced Liquid Processing System), until the concentrations of all radioactive substances besides tritium satisfy the safety regulatory standards. As for tritium, the water is significantly diluted with seawater before the discharge into the sea so that it fully satisfies safety regulatory standards.
