Tokyo Electric Power Co, TEPCO, said 10,400 tons of low-level radioactive water, left by the tsunami, had been pumped back into the sea in order to free up storage capacity for highly contaminated water from the reactors.
The government announced earlier that because of accumulated radiation contamination, it would encourage people to leave certain areas beyond its 20 km (12 mile) exclusion zone around the plant. Thousands of people could be affected by the move.
