Atom probe tomography (APT) provides three-dimensional compositional mapping with sub-
nanometre resolution. The sensitivity of APT is in the range of parts per million for all …

To efficiently capture the energy of the nuclear bond, advanced nuclear reactor concepts
seek solid fuels that must withstand unprecedented temperature and radiation extremes. In …

Experimental work aimed at understanding the role of dislocation loops in limiting phonon
mediated thermal transport in ceramics is presented. Faulted dislocation loops, having …

The early stage of microstructural evolution of ThO2, under krypton irradiation at 600, 800,
and 1000° C, was investigated using in situ transmission electron microscopy (TEM) …

The Mg alloys with combination of high strength and excellent irradiation resistance are
currently required for research reactors. In this work, the novel Mg-3Mn-0.5 Ca alloy with a …

In situ characterization of defects, microstructure, and properties will provide new
perspectives regarding the structure-property relationship of materials in extreme …

Thermal transport in materials used for energy applications is a physical process directly tied
to performance and reliability. As a result, a great deal of effort has been devoted to …

As an alternative to traditional uranium dioxide (UO 2) fuels, mixed oxide (MOX) fuels were
developed to dispose of industrial and military stores of plutonium (Pu) through the …

Transmission electron microscopy experiments coupled with 4 MeV Au and 390 keV Xe
implantations were conducted on polycrystalline UO 2 thin foils in order to study the void …

The coupled effects of nuclear and electronic energy losses were investigated in uranium
dioxide (UO 2). Single and sequential ion irradiations were carried out with 92 MeV Xe ions …
