SPOKANE, Wash. — Staff on the Hanford Nuclear Reservation in Washington state have completed stabilizing a partially-collapsed tunnel containing radioactive wastes left over from the manufacturing of plutonium for nuclear weapons.

The U.S. Division of Power stated Tuesday the tunnel was full of greater than four,four hundred cubic yards of grout meant to stop any further collapse.

The tunnel partially collapsed earlier this yr, prompting a quick alarm on the website that required some three,000 staff to shelter in place. Nobody was injured.

Since early October, crews labored principally at night time to inject the grout, which is meant to scale back the danger of additional collapse.

Hanford is situated close to Richland and was created in the course of the Manhattan Venture in World Struggle II. It made a lot of the plutonium for the nation’s nuclear stockpile.
