On May 18, 2022, the Japan Atomic Energy Regulatory Commission granted initial approval for TEPCO’s ocean dumping plan.Īfter the Fukushima nuclear accident, the Japanese government set up the “Nuclear Damage Compensation and Decommissioning Facilitation Corporation” (NDF), which is an official agency with 50.1 percent of TEPCO’s voting rights, in order to prevent TEPCO from going bankrupt. So in April 2021, the Japanese government announced that the problem of increasing amounts of nuclear contaminated wastewater would be addressed by dumping it into the sea.

A decade on, the nuclear contaminated water generated by the Fukushima Daiichi Nuclear Power Plant are about 150 tons per day in 2021, and will reach the upper limit of the storage tank capacity of 1.37 million tons in the spring of 2023.Īccording to estimates by the Japan Centre for Economic Research, it will cost 50-70 trillion yen (about $400-550 billion) to scrap and decontaminate the reactor, the bulk of which goes to the treatment of contaminated water. And because the used seawater became highly contaminated with radioactive material, TEPCO had to put it in storage tanks.

The operator of the plant, Tokyo Electric Power Company (TEPCO), decided to pour in seawater to cool the reactor and contain the leakage. In 2011, the “3/11” earthquake in Japan caused the meltdown of the Fukushima Daiichi Nuclear Power Plant reactor core, unleashing enormous amounts of radioactive material.
