The term "Reprocessing Unit" is misleading as no waste will be recycled there. Basically Plutonium will be produced in such a facility. For this the spent fuel (originally the fuel consists of Uranium-235 and Uranium-238) will be transformed into three main fractions:

  1. remaining Uranium (ca. 95 %),
  2. Plutonium (ca. 1 %; created not until before operation in the reactor), and
  3. fission products (ca. 4 %; Caesium-137, Strontium-90, Technetium-99, Iodine-129 etc. - all created not until before operation in the reactor).[1]

Usually the Plutonium will be used for the construction of nuclear bombs or as an addition for the production of so called MOX (mixed oxides) fuel elements.[1]
