Abstract
In this project, systematic investigations on the Tc-Zr binary metal system will be evaluated for the first time. The synthesis of metallic Tc as well as its alloys with Zr will be evaluated. In order to provide valuable data to AFC R&D, the thermodynamic equilibrium phases, as well as their performance under repository conditions, will be examined.
The research objectives of this project are as follows:
• Evaluate anion exchange methods for achieving the separation of Tc from U.
• Synthesize metallic Tc from the separated product.
• Synthesize and characterize Tc alloys.
• Investigate Tc-corrosion and Tc-leaching of binary Tc-Zr phases under a range of conditions.
The following experimental techniques are used in the evaluation of the solutions and solids from the experiments: ultravioletvisible spectroscopy, time-resolved laser fluorescence spectroscopy, X-ray Absorption Fine-Structure Spectroscopy (XAFS), and microscopy.
