Japan officials now say it could take months to get Fukushima Daiichi under control, followed by years of cleanup and containment. Workers attempted to use concrete to seal a crack in a pit at the No. 2 reactor that was spewing radioactive fluid directly into the Pacific Ocean. When that method failed, they turned to water-absorbent polymers to stop the leak. But it now appears there may be another source of leakage. Meanwhile, the plant's operator discovered the bodies of two workers who had been missing since the day of the earthquake and tsunami. They are the first two workers at Fukushima Daiichi to have died in the aftermath of the disasters. TEPCO linked the deaths of Kazuhiro Kokubo, 24, and Yoshiki Terashima, 21, to the tsunami, saying the workers lost great amounts of blood and went into shock.
