Radioactive waste remains the most controversial issue in the use of nuclear energy, along with the fear of nuclear accidents such as Fukushima or Chernobyl.

Every year, nuclear reactors around the world produce energy that is considered clean, as well as more or less radioactive waste that is carefully processed, stored, and inventoried.
