International cooperation in the monitoring of radiation levels in seawater near the disabled Fukushima Daiichi nuclear power plant continues. Scientists from China, South Korea, and Switzerland were recently joined by International Atomic Energy Agency director general Rafael Mariano Grossi as they collected seawater samples under the “additional measures” framework, which was adapted in 2024 to increase the participation of other countries and enhance the transparency of the IAEA-led analyses.

An International Atomic Energy Agency team of experts said in a review published on April 2 that the two options for the controlled disposal of treated water stored at the Fukushima Daiichi nuclear power plant are “technically feasible.” A Japanese advisory subcommittee outlined the two options—vapor release and discharge to the sea—for the water that is being stored at the plant following the 2011 accident.
