Back in May, a train tunnel at the Hanford nuclear site partially collapsed. Federal contractors have now just finished filling it up with grout. It took about 520 truck loads of grout to fill the tunnel.

Crews had been doing the work mostly at night since early October.

At the Hanford Site, the job to seal in a tunnel full of radioactive waste is nearly half done according to the federal government. It became a high-priority project when the tunnel partially collapsed this past May, causing an emergency at Hanford.

This spring, an underground train tunnel full of radioactive waste was discovered partially collapsed at the Hanford Site in southeast Washington state. Now, federal contractors are prepping the site to fill the unstable tunnel with grout. They’re planning to start Tuesday night.

Crews at the Hanford Site in southeast Washington state are running through rehearsals and last minute details. In early October, they’ll begin pouring grout, a kind of thin cement, into a partially collapsed tunnel full of highly contaminated radioactive waste.

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:

In the wake of a tunnel collapse at the Hanford nuclear site in May, the U.S. Department of Energy plans to take public comments at a meeting in the Tri-Cities on July 20 on how it should proceed with the clean-up.

The Hanford nuclear reservation in southeast Washington state has two train tunnels full of very hot radioactive waste—and both tunnels are in danger of further collapse. That’s according to a new report commissioned by the U.S. Department of Energy.

Grouting up a tunnel that was found collapsed last month at Hanford is the best option according to Washington state’s top expert on Hanford. And it won’t preclude further cleanup of the radioactive waste inside.

Leaders and technical experts at the Hanford nuclear site have decided to fill a tunnel that partially collapsed last month with grout. That tunnel is full of radioactive waste.
