The 56 million gallons of radioactive waste created from decades of plutonium enrichment at Hanford are stored in 177 massive, underground tanks on 18 different "farms" spread out over the 580 square miles of the nuclear reservation in Washington state. Most of the tanks are single-shelled, but 28 of them are double-shelled, which helps prevent waste from getting into the ground. Each tank holds between 55,000 and a million gallons of toxic waste.
