After Tokyo Electric Power Company reported that they had stopped the leak in Reactor 2’s pit, an NHK helicopter took video of the Fukushima Daiichi plant, showing not only smoke coming from the reactors, but water still pouring into the ocean.
Today, TEPCo admits that plugging the leak in the pit will only cause new leaks to show up. That’s because they don’t know exactly where the leaking water is coming from, or how it made its way to the pit.
