ANALYSIS: How long will radioactive water leak from crippled reactors?

Water puddles with high levels of radioactivity detected in the basements of the turbine buildings at three reactors of the crippled Fukushima No. 1 nuclear power plant raise questions about the status of the pressure containers.
The contaminated water was likely due to a melting of fuel rods in the reactor cores.
The prevailing view among experts is that the fuel rods began collapsing within the No. 1, No. 2 and No. 3 reactors between March 12, a day after the Great East Japan Earthquake struck, and March 14. It probably did not take long for the fuel rods to lose their original form.
