Abstract

In a method of separating neptunium and plutonium, a nitric acid solution containing a mixture of neptunium and plutonium is oxidized by irradiation of ultraviolet light in the presence of a reducing agent. As a result, different valences of neptunium are adjusted all into the valence 5, which can remain in water, and in the meantime, valences of plutonium are adjusted into the valence 4 or 6, which can be extracted in the organic phase. It is therefore possible to separate neptunium and plutonium from each other without difficulty.
