"Japanese authorities, now struggling to contain leaks of radioactive groundwater from the wrecked Fukushima nuclear plant, were urged two years ago by U.S. experts to take immediate steps to prevent groundwater contamination but decided not to act on the advice."

"LOS ALAMOS, N.M. -- At Los Alamos National Laboratory, a seven-year, $213 million upgrade to the security system that protects the lab's most sensitive nuclear bomb-making facilities doesn't work.

Ed Lyman, from the Union of Concerned Scientists, tells host Steve Curwood that the new ice wall plan is likely an act of desperation, and that some American reactors are at risk for the same kind of flooding disaster."

"More than 50 years into the age of nuclear energy, one of the biggest growth opportunities may be junking old reactors."
