OLYMPIA, Wash. (AP) - Radioactive waste tanks may be leaking some 1,000 gallons per year at Hanford Nuclear Reservation, and Washington Gov. Jay Inslee said Wednesday officials are still evaluating how to effectively remove the remaining material from the problematic tanks.
The 1,000-gallon figure is a rough estimate based on the early assessment of six identified leakers. Inslee said the leakage numbers are still being evaluated to determine exactly how much has been lost and how fast the waste is leaving the tanks.
Inslee said there's no available technology to plug the leaks, so federal and state officials are working to find the best available solution to remove the sludge. Inslee said that solution could come in weeks or months.

Hanford has 177 aging tanks that store millions of gallons of radioactive sludge. Inslee said faulty data analysis meant officials did not properly catch signs of leaking before now, and Inslee expressed concern about the other tanks at the reservation.
