SALT LAKE CITY — The Salt Lake Tribune - DOE: Trainloads of nuke waste on way to Utah

.

A Department of Energy official on Thursday informed U.S. Rep. Jim Matheson, D-Utah, that 11,000 tons of the low-level radioactive waste -- packed in 14,800 drums -- is ready to be shipped from the Savannah River cleanup in South Carolina.

.

Ultimately, about 10,000 metric tons of depleted uranium will make its way to Utah.
.
Depleted uranium is different from other waste disposed at EnergySolutions Inc.'s facility 70 miles west of Salt Lake City because it becomes more radioactive over time, for up to 1 million years. The material is a byproduct of the uranium enrichment process used to make nuclear weapons during the Cold War era.
