TRP 19. Dissolution, Reactor, and Environmental Behavior of ZrO2-MgO Inert Fuel Matrix
July 2004 - Current
Research Objectives & Methods
This project examines inert fuels containing ZrO2 and MgO as the inert matrix. Ceramics with this inert matrix, Ce, U and Pu will each be synthesized and examined. This project will provide the necessary data for evaluating the performance, reprocessing, and waste behavior of the MgO-ZrO2 fuels from a quantified, chemical perspective.
The research objectives of this project are as follows:
- To examine the neutronic behavior of MgO-ZrO2 inert fuels. Results will be used as parameters for fuel composition.
- To synthesize and characterize MgO-ZrO2 ceramics containing burnable poison and fissile composition. Synthesis is based on a precipitation method. Results will be applied to behavior in high temperature water, acid, and environmental conditions.
- To describe the chemical behavior of synthesized ceramics.
- To utilize project data in kinetic and thermodynamic modeling codes to evaluate the speciation of the elements in the ceramics under reactor, reprocessing, and repository conditions.
