A Glass Nightmare: Cleaning Up the Cold War’s Nuclear Legacy at Hanford


How to clean America’s most polluted place

The Hanford Site in Washington state has been called the most polluted place in the Western Hemisphere: during the Cold War, it produced plutonium for more than 60,000 nuclear weapons. Now, engineers are struggling to clean up the radioactive mess left behind — in particular, 177 ageing tanks, inside which “watery liquids rest atop goop as thick as peanut butter and salt cakes resembling wet beach sand”. A plan to secure the waste by turning it into glass has been in the works for decades, and could end up costing as much as US$550 billion and last 60 years.
