Hundreds of people marched in South Korea’s capital on Saturday demanding Japan to scrap its plans to release treated wastewater from the damaged Fukushima nuclear power plant as the head of the United Nations’ nuclear agency met with senior Seoul officials to discuss public concerns over foods safety. The protests came a day after South Korea’s government formally endorsed the safety of the Japanese plans, saying that the contamination levels of water pumped out from the plant would be within acceptable standards and wouldn’t meaningfully affect South Korea as long as the Japanese treatment systems work as designed.
