The U.S. Department of Energy rolled out several options at a public meeting Thursday night to stabilize what’s known as Tunnel 2 at the Hanford nuclear reservation in southeast Washington. Stabilizing the tunnel became a priority after nearby Tunnel 1 was found partially collapsed this spring.

Tunnel 2 is filled with highly-radioactive equipment leftover from a plutonium plant, and the feds say it's also in danger of collapse.

At the meeting, they presented a raft of ideas to stabilize it:
