“Japan’s nuclear agency has upgraded the severity level of a radioactive water leak at the Fukushima plant from one to three on an international scale. Japanese reports say it is a provisional move that had to be confirmed with the IAEA, the UN’s nuclear agency. This week is the first time that Japan has declared an event on the Ines scale since the 2011 earthquake and tsunami. The move was announced in a document on the agency’s website and was subsequently approved at a weekly meeting of the regulatory body. Shares of plant operator Tokyo Electric Power Company (Tepco) fell as much as 13% to 537 yen.”
