Highly radioactive water flooding the Fukushima power plant's No. 3 reactor will be transferred to a waste-disposal facility Tuesday to prevent it from tainting the environment, Tepco said Monday. The move is essential to preventing the excess water from contaminating the environment and to repairing the reactor, which was damaged by the March 11 quake and tsunami. The water, which was sprayed into the building earlier to prevent the reactor's core from melting down, is preventing workers from entering and may also be leaking into the adjacent turbine building and other places.
