Evolution of Defects and Interfaces in Ceramics under Irradiation
EMSL Project ID
34899
Abstract
The proposed work is to develop atomic-level understanding of the production and evolution of defects and interfaces in ceramics under ion and electron irradiation. Research will also focus on the role of interfaces on dynamic defect recovery, phase transitions, and diffusion in materials relevant to environmental, energy and national security missions. The work will focus on atomic-level properties of surfaces and interfaces and their roles as defect sinks and traps for gas and impurity atoms. This work is relevant to nuclear waste immobilization, the hydrogen economy, fuel cell technology, materials for a closed nuclear fuel cycle, materials for advanced nuclear power technology, and advanced radiation detector technology. The proposal will employ multiple experimental facilities and techniques in EMSL. Much of the work will be performed in situ using ion-beam analysis, electron microscopy techniques, or optical spectroscopy. This proposed work will include a theoretical and computation effort that is integrated and closely coupled to the experimental effort. The defect processes of primary interest are defect production and formation, defect migration, defect interactions, and defect mechanisms related to the kinetics of irradiation effects, ion implantation, ionic transport, and phase transformations in ceramics. The research approach and management philosophy are based on a team of highly-motivated experimental at PNNL and external collaborators who perform highly-integrated studies with computational scientists on defect evolution in related materials.
