Between 1946 and 1990, more than 200,000 tons of uranium ore were mined. When uranium mining was discontinued in 1990, huge areas of overburden rubble and sludge had to be remediated at a cost of around 8 billion euros. Old shafts had to be filled, dumps were secured and planted, radioactive equipment had to be brought underground.
