ABSTRACT:
A process for reducing and dissolving PuO.sub.2 comprises contacting the plutonium dioxide with a hydrazine-free, acid aqueous solution containing a reducing agent, whose redox potential is below +0.5 V/ENH in order to reduce and dissolve the plutonium. The reducing agent can be Cr.sup.2+ or U.sup.4+.
