1. A single integrated system for recycling used nuclear fuel (UNF) emerging from a reactor comprising:
a decladding vessel separating fuel pellets from nuclear fuel rods via oxidation to produce U3O8;
a fluorination vessel coupled to the decladding vessel to remove hexafluorides from the U3O8 produced by the decladding vessel; and
an electrowinning vessel coupled to the fluorination vessel removing plutonium and actinides via electrowinning.
