TOKYO (Reuters) - Tokyo Electric Power Co is struggling to stop groundwater flooding into damaged reactors at its wrecked Fukushima plant and it may take four years to fix the problem, possibly delaying the removal of melted uranium fuel.
A March 11, 2011, earthquake and tsunami knocked out cooling equipment at the company's Fukushima Daiichi plant north of Tokyo, triggering the worst atomic disaster since Chernobyl in 1986. More than 160,000 people were forced from their homes.
