Tunnel collapses at Hanford; no radiation released, officials say | KING5.com: Hundreds of workers were told to take cover at the Hanford Nuclear Reservation after a tunnel full of highly contaminated materials collapsed Tuesday morning. But officials say no radiation was released and no workers were hurt.
Officials say a collapsed patch of ground above the tunnel was larger than first believed. The U.S. Department of Energy said the collapse covered about 400 square feet (37.1 square meters) instead of the 16 square feet (1.4 square meters) first reported.
