TRP 36. Evaluation of Cs/Sr Waste Forms for Long Term Storage and Disposal
May 2007 - Current
Research Objectives & Methods
The goal is the development, characterization, and optimization of the proposed aluminosilicate waste form for a separated cesium and strontium waste stream. The research effort at UNLV will be divided into two subtasks:
- Materials compatibility, and
- Waste form optimization and performance.
The materials compatibility subtask will examine the potential for chemical interactions between the waste form material and proposed structural materials for the disposal container (carbon steel, stainless steel, etc.). The waste form performance task will examine the leach resistance of the waste form, with particular attention to barium retention.
The research objectives of this project are:
- To characterize the Cs/Sr-loaded aluminosilicate waste form ceramic,
- To examine the impact of fabrication process parameters on the product waste form,
- To evaluation the potential for waste form – container material chemical interactions, and
- to examine the degradation/alteration behavior of the waste form.
