A vitrification system, comprising: a vitrification container; a lid attached to the vitrification container, wherein the attached lid forms a sealed vitrification container; two or more electrodes wherein the two or more electrodes are operatively positioned through the lid and extend down into the vitrification container; two or more electrode seal assemblies (300, 400) affixed to the lid, wherein the two or more electrode seal assemblies (300, 400) provide insulation for the two or more electrodes and characterized in that each of the two or more electrode seal assemblies (300, 400) comprises: a housing (310, 410), wherein the housing (310, 410) comprises of two halves; two or more ring grooves (375, 475) recessed into the housing (310, 410) such that two or more sealing rings with a split can be placed into the two or more ring grooves (375, 475), and wherein the placement results in external faces of the two or more sealing rings recessed into the ring grooves (375, 475); one or more gas galleries (330, 430) at least one of machined and cast into the housing (310, 410) such that the gas galleries (330, 430) are adjacent to the two or more ring grooves (375, 475), wherein the one or more gas galleries (330, 430) distribute gas onto the external faces of the two or more sealing rings from interior faces of the two or more ring grooves (375, 475), wherein the distributed gas causes a change in pressure resulting in the two or more sealing rings compressing onto the electrodes and forming seals. a vitrification container; a lid attached to the vitrification container, wherein the attached lid forms a sealed vitrification container; two or more electrodes wherein the two or more electrodes are operatively positioned through the lid and extend down into the vitrification container; two or more electrode seal assemblies (300, 400) affixed to the lid, wherein the two or more electrode seal assemblies (300, 400) provide insulation for the two or more electrodes and characterized in that each of the two or more electrode seal assemblies (300, 400) comprises: a housing (310, 410), wherein the housing (310, 410) comprises of two halves; two or more ring grooves (375, 475) recessed into the housing (310, 410) such that two or more sealing rings with a split can be placed into the two or more ring grooves (375, 475), and wherein the placement results in external faces of the two or more sealing rings recessed into the ring grooves (375, 475); one or more gas galleries (330, 430) at least one of machined and cast into the housing (310, 410) such that the gas galleries (330, 430) are adjacent to the two or more ring grooves (375, 475), wherein the one or more gas galleries (330, 430) distribute gas onto the external faces of the two or more sealing rings from interior faces of the two or more ring grooves (375, 475), wherein the distributed gas causes a change in pressure resulting in the two or more sealing rings compressing onto the electrodes and forming seals. a housing (310, 410), wherein the housing (310, 410) comprises of two halves; two or more ring grooves (375, 475) recessed into the housing (310, 410) such that two or more sealing rings with a split can be placed into the two or more ring grooves (375, 475), and wherein the placement results in external faces of the two or more sealing rings recessed into the ring grooves (375, 475); one or more gas galleries (330, 430) at least one of machined and cast into the housing (310, 410) such that the gas galleries (330, 430) are adjacent to the two or more ring grooves (375, 475), wherein the one or more gas galleries (330, 430) distribute gas onto the external faces of the two or more sealing rings from interior faces of the two or more ring grooves (375, 475), wherein the distributed gas causes a change in pressure resulting in the two or more sealing rings compressing onto the electrodes and forming seals.
