Since then, contaminated water has been pumped into storage units and gradually treated using the Advanced Liquid Processing System (ALPS) to eliminate most radionuclides, [3] [7] except notably tritium with a half-life of 12.32 years. [8] [9] In 2021, the Japanese cabinet approved the release of ALPS-treated water containing tritium.

Tepco says it intends to discharge approximately 460 tons of treated water daily
Japan began pumping more than a million metric tons of treated radioactive water from the destroyed Fukushima Daiichi nuclear power plant on Thursday, a process that will take decades to complete.
In 2020, the storage of contaminated water reached over a million tons, stored in large containers at the grounds of the plant. [85] It was predicted that in 2022, the storage capacity could be exceeded. Therefore, a proposal was made in spring 2020, to start discharging the cooling water into the ocean.
The release that began on Thursday morning will run for about 17 days, as about 7,800 cubic metres (275,454 cubic feet) of the water is discharged into the Pacific Ocean, Tepco said in a statement.
In July 2022, Japan's Nuclear Regulation Authority approved discharging the treated water into the sea. [205] Japan said the water is safe, many scientists agreed, and the decision came weeks after the UN's nuclear watchdog approved the plan; but critics say more studies need to be done and the release should be halted.
