Japan’s nuclear watchdog, the Nuclear Regulation Authority, yesterday said the revealed leaking of an estimated 300 metric tons of radioactive water at the damaged Fukushima Nuclear Power Plant was a “serious incident”, level three on the seven-part international scale.
Tokyo Electric Power Company (TEPCO), who run the plant, announced the leak last week and the new accident’s level-three rating was made after consultation with the International Atomic Energy Agency. However, the Nuclear Regulation Authority notes this estimate may be overstated as it relies on the leaking tank being full before the leak began.
There is no gauge to measure water quantities inside the tank, used to store contaminated water after the initial accident. Water is being collected at a rate of 400 tons per day, and an unknown quantity of radioactive groundwater is flowing into the sea.
