Hanford:a site crucial to the secret Manhattan Project. Plutonium for weapons produced there for 4 decades. NOT nuclear power plant. pic.twitter.com/Uq2Pce0QX4— Susannah Frame (@SFrameK5) May 11, 2017
On 9 May 2017, a 20-foot-long section of a nuclear waste storage tunnel collapsed at the Hanford Site in Washington State, USA. The collapse occurred at the 20-foot-wide join of two tunnels, possibly exposing the contents to the open air, although Hanford denied this. Hanford is famous for producing plutonium for nuclear weapons during the Cold War. It is also famous for its contamination and leaking tanks of waste, making it one of the most toxic sites in the United States.
