ABSTRACT:
A process is disclosed for volume reduction and solidification of a radioactive waste solution mainly composed of sodium borate and discharged from a pressurized water reactor. The process comprises adding to said radioactive waste solution, ZnO or a mixture of ZnO with Al.sub.2 O.sub.3 and/or CaO, and then subjecting the resulting mixture to dehydration and melting to produce a vitrified solid solution. Said process is safe and reliable. A vitrified solid solution produced by said process is safe and stable.
