In an effort to speed up the draining of its Fukushima Dai-ichi nuclear plant, Tokyo Electric Power Co. said today that it will release 11,500 tons of low-level radioactive water into the Pacific Ocean. Ten thousand tons of water flooded a radioactive waste processing facility after last month's earthquake and tsunami; once drained, Tepco will use the facility to store the highly radioactive water currently in the basement near the No. 2 reactor. Japan's nuclear watchdog endorsed the plan and called it "inevitable," the Wall Street Journal reports. (More Tepco stories.)
