The utility Tokyo Electric Power Co (Tepco), which operated the damaged Fukushima Daiichi nuclear power plant, has been given permission by Japan’s nuclear authority to begin discharging more than a million tonnes of radioactive water.
On Tuesday, the global watchdog, the International Atomic Energy Agency (IAEA), said a two-year review showed Japan’s plan for the release would have negligible environmental impact.
The Japanese regulator’s certificate is the final step the utility required to begin the process.
