K-East Basin Filled with Sand

Posted: Updated:

RICHLAND, Wash.- A pool once considered the Hanford site's biggest danger to the Columbia River is full of sand.  

Workers pumped 514 truckloads of a cement-sand mix into the K-East Basin over the weekend in preparation to tear the building down.  

The sand filler will allow demolition equipment to drive over the nuclear fuel pool and rip down the surrounding building.

"All the risk right now to the public from the leaking water down through a leaky basin is now gone, it's stabilized and now we can do systematically work our way down to the waste site beneath and clean it up so we're getting close to having the river protected from this basin," said Bob Wilkinson with Fluor Hanford.

The basin once held much of Hanford's nuclear fuel.  

It is thought to have leaked radioactive water into the soil.  

Workers finished draining water from the pool earlier in the month.
