Process of vitrifying radioactive liquid waste with suppressed formation of gaseous ruthenium
First Claim
1. A 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 said cartridge to vitrify said liquid waste, characterized in that a radioactive liquid waste containing ruthenium is absorbed together with a reducing agent in liquid form into said glass frit cartridge, thereby suppressing the formation of gaseous ruthenium during the heat melting.

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.

- 8. A 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 said cartridge to vitrify said liquid waste, characterized in that a reducing agent in solid form is previously incorporated in said glass frit cartridge made of molded glass fibers, and a radioactive liquid waste containing ruthenium is then absorbed in to said glass frit cartridge containing said reducing agent, thereby suppressing the formation of gaseous ruthenium during the heat-melting.
