CX-270191: Immobilization of High-Level Waste Salt in Dechlorinated Zeolite Waste Forms – University of Utah

The University of Utah, in collaboration with Idaho National Laboratory, proposes to evaluate the main challenges associated with the disposal of electrorefiner salt: maximization of fission products in a final waste form and the associated processing costs. The proposed research will focus on two main objectives to overcome these process- and economic-related challenges: 1) dechlorination of the electrorefiner salt and 2) synthesis of a sintered waste form. To accomplish the objectives, the research will work to optimize process conditions for dechlorination of salts using H-Y zeolite, validate the dechlorination process using simulated electrorefiner salt, and develop glass binder material and waste for sintering process.
