TRP 16. Evaluation of Fluorapatite as a Waste-Form Material
August 2002 - December 2006
Research Objectives & Methods
The following were the specific research objectives:
- To develop a waste matrix for the disposal of the fission product waste stream from the Flouride Extraction (FLEX) Process;
- To develop a process to make synthetic fluorapatite that incorporates the FP-bearing ZrF4 salt;
- To develop a fundamental understanding of the chemistry of this new waste form in order to better predict its long term behavior in a repository environment;
- To develop a fundamental understanding of natural, fluoride-bearing mineral phases to use as natural analogs to bound the predicted behavior of the FLEX fission product waste stream.
The research effort was divided along two parallel paths: the Fabrication Path, led by collaborators at the Khlopin Radium Institute (KRI) in St. Petersburg, Russia; and the Characterization Path, led by researchers from UNLV.
