US government works to 'cocoon' old nuclear reactors

The decommissioned plutonium-producing DR reactor, left, and D reactor, right, are shown on the Hanford Nuclear Reservation, June 13, 2017, near Richland, Wash. The federal government is moving forward with the cost-saving "cocooning" of eight plutonium production reactors at Hanford that will place them in a state of long-term storage for decades to allow radiation inside to dissipate until they can be dismantled and buried.
