3 Plutonium-Tainted Structures At High Risk Of Collapsing At Hanford

“Richland, WA — Three radioactively contaminated underground structures at high risk of collapse on the Hanford nuclear reservation could be filled with concrete-like grout within a year.

The Department of Energy has concluded they could fail and release radioactive contamination.

“A number of structures are overstressed and at risk of age-related failure, which could result in a release of contamination with impacts to human health and the environment,” DOE said in a letter last week to the Environmental Protection Agency, a Hanford regulator.”
