"The Department of Energy has confirmed that its oldest double-shell tank is actively leaking radioactive and hazardous chemical waste from its inner shell."

"DOE made the announcement Monday after a video inspection of the area between the shells Sunday showed more waste in one place than a video taken Thursday showed.

"It's a very, very small volume," said Tom Fletcher, DOE assistant manager for the tank farms. Although there's no good way to measure the amount, it could be a couple of tablespoons of additional waste between the video inspections.

Tank AY-102 is the first of Hanford's double-shell tanks known to have leaked waste from its inner shell."
