Workers wear protective masks as they work at the construction site of upper stream storage to release Advanced Liquid Processing System (ALPS) treated water into the sea, at the disabled Fukushima Dai-ichi nuclear power plant in Okuma town, Fukushima prefecture, Japan, March 8, 2023. The Tokyo Electric Power Co (TEPCO), which runs the crippled nuclear power station, plans to soon start releasing into the sea more than a million tons of radioactive water from the plant that was used to cool the reactors in the aftermath of the March 11, 2011 tsunami, assuring the water is treated, filtered, diluted and safe. "What we say to the fishermen is that we have equipment to treat the water safely," Tomohiko Mayuzumi, a Tepco spokesperson, told Reuters at the plant.
