ABSTRACT:
An improved process of vitrifying a radioactive liquid waste by absorbing a radioactive liquid waste into a glass frit cartridge made of molded glass fibers and heat-melting the cartridge to vitrify the liquid waste. The invention is characterized by absorbing a radioactive liquid waste containing ruthenium into the glass frit cartridge together with a reducing agent. By the process of the invention, the formation of gaseous ruthenium is effectively suppressed during the heat-melting.
