| Abstract Scope |
To best elucidate the microstructural evolution of materials under the complex extreme environments associated with advanced nuclear material needs for next generation reactors, fusion energy systems, and space nuclear propulsion concepts, a twenty first century tool set needs to be developed. The Tennessee Ion Beam Materials Laboratory is undergoing an evolution to meet these needs. This is done in two parts. First, the range of controlled thermal, irradiation, mechanical, magnetic, and corrosive environments have been expanded. Second, the ability to track the microstructural and subsequent property evolution during the exposure to controlled extreme environments has greatly advanced. This is made possible through advancements in integrating acoustic emission, transient grating spectroscopy, small-scale mechanical testing, ion beam induced luminescence, transmission electron microscopy with laser and ion irradiation capabilities. Better testing in controlled radiation environments will permit validation and refinement of predictive models and increased trust in materials for these emerging energy concepts. |
