Hanford Nuclear Waste Cleanup Plant May Be Too Dangerous

[Bok]

The most toxic and voluminous nuclear waste in the U.S.--208 million liters --sits in decaying underground tanks at the Hanford Site (a nuclear reservation) in southeastern Washington State. It accumulated there from the middle of World War II, when the Manhattan Project invented the first nuclear weapon, to 1987, when the last reactor shut down. The federal government’s current attempt at a permanent solution for safely storing that waste for centuries--the Waste Treatment and Immobilization Plant here--has hit a major snag in the form of potential chain reactions, hydrogen explosions and leaks from metal corrosion. And the revelation last February that six more of the storage tanks are currently leaking has further ramped up the pressure for resolution.
