RICHLAND, Wash. — The U.S. Department of Energy and its regulators have proposed extending the deadline to ship waste contaminated with plutonium off the decommissioned Hanford nuclear reservation in Washington state.
The proposal moves the deadline back 20 years — from 2030 to 2050 — to ship the waste to a national repository in New Mexico for permanent disposal, the Tri-City Herald reported Wednesday.
“We realized that the existing milestone dates were unachievable,” said John Price, a manager with the state Department of Ecology, which is a regulator for the nuclear site.
The Hanford nuclear reservation produced plutonium for nuclear weapons during the Cold War and World War II, leaving 56 million gallons (212 million litres) of radioactive waste in underground tanks. The 580-square-mile (1,500-square-kilometer) site is located in Richland, Washington about 200 miles (322 kilometers) southeast of Seattle.
Price also said there were some newly proposed deadlines that the Department of Ecology “enthusiastically” supports, including a commitment by the Department of Energy’s to start shipping some waste as early as 2028.
The federal agency and its regulators — the Department of Ecology and the Environmental Protection Agency — set waste cleanup plans and deadlines for the nuclear site.
The latest proposed deadlines cover suspected transuranic waste, or debris contaminated with plutonium, including about 11,000 containers stored at a Hanford complex.
Waste with artificially-made elements above uranium on the periodic table is also classified as transuranic.
A public meeting to discuss the latest proposed changes and answer questions was scheduled for Thursday.
