  • Mitigation of secondary phase formation during waste vitrification
    Patent number: 8951182
    Abstract: A method for vitrification of waste to reduce the formation of persistent secondary phases comprising separating at least one glass frit constituent from an initial glass frit to form a modified glass frit. The waste, modified glass frit, and the at least one glass frit constituent are mixed together with the modified glass frit and the at least one glass frit constituent being added as separate components. The resulting mixture is vitrified.
    Type: Grant
    Filed: September 9, 2013
    Date of Patent: February 10, 2015
    Assignee: EnergySolutions, LLC

  • Mitigation of secondary phase formation during waste vitrification
    Patent number: 8530718
    Abstract: A method for vitrification of high level waste to reduce the formation of persistent secondary phases comprising the steps of providing a high level waste for vitrification; providing a glass frit additive for mixing with said high level waste; redistributing selected constituents of said glass frit for mixing separately as raw chemicals with said high level waste; and, feeding said high level waste, said glass frit additive, and the redistributed glass frit constituents to a melter for vitrification of said high level waste so that formation of secondary phases is suppressed.
