PORTLAND, Oregon - On Tuesday, an emergency was declared at the Hanford Nuclear site in Washington after a tunnel that collapsed containing rail cars full of nuclear waste.
The former nuclear production site was locked down at 8:30 a.m. Tuesday after a inspection revealed that soil had collapsed over a portion a 20-foot-long section of the tunnel. It was storing contaminated railcars.
There was no contamination or injuries reported at the site. Emergency workers said they would continue to monitor the area as a crew prepared to fill the hole with clean soil, energy officials said.
"The incident is moving from the emergency phase towards the recovery phase. The workforce has safely left the site, other than personnel essential to the recovery plan," the DOE said in a statement late Tuesday. "After extensive testing the site remains confident at this point that there has been no indication of worker exposure or an airborne radiological release."
Non-essential workers, who were initially advised to stay in place, have been released, but some workers were advised not to report for graveyard shift on Tuesday night.
