b'Developing Multi-Scale,Integrating multiple characterization technologies accelerates materials Rapid, and Comprehensivedevelopment through faster data acquisition and correlation.Post-Irradiation ExaminationT he current qualification cycle for nuclear fuels and materials is a multi-decade process that must be accelerated to bring many advanced reactor using the Focused Ionconcepts into reality. This research focused on accelerating comprehensive BeamMicroscope characterizations of the microstructure and physical properties of irradiated fuels and materials providing higher quality correlated data. Current approaches to post-irradiation examination of materials are based on the use of single-purpose instruments, proceeding through a sequential process that provides incomplete characterization. Multiple samples are laboriously prepared and moved from instrument to instrument in an inefficient and uncorrelated process flow. Modern instrumentation TOTAL APPROVED AMOUNT:with the capability for multi-modal analysis and automation offers the potential to $821,500 over 3 years radically improve the characterization data acquisition rate, the breadth of the data streams produced, and the data correlation. We developed technology based on dual-PROJECT NUMBER:beam FIB and scanning electron microscopy platforms. These instruments incorporate 19A39-024 separate ion and electron beams and include sample micromanipulation devices and PRINCIPAL INVESTIGATOR:tomographic imaging capabilities that provide the unique potential to incorporate Daniel Murray many different characterization techniques into a single instrument. The resulting data streams are essential for understanding irradiation effects on materials and are ideal CO-INVESTIGATORS: for the development and validation of mesoscale models, which are necessary for the Mukesh Bachhav, INL development of accurate engineering-scale models.Wade Marcum, Oregon State University TALENT PIPELINE:Robert Powers, student at Oregon State UniversityPRESENTATION:Murray, D., F.
