Operational waste from the nuclear power plants

 

Operation of the nuclear power plants produces low-level waste such as protective suits, shoes, cleaning materials, contaminated metal components and air filters. Some low-level waste can be incinerated in the ZWILAG plasma furnace and solidified to form a slag-like mass, as seen in the photograph. (Image: Nagra)
