NE Colloquium. Kristian Myhre - "How Nuclear Materials Behave and Radiochemical Processes Function"
An in-depth understanding of how nuclear materials behave and radiochemical processes function is required for the advancement of nuclear energy, security, and medical technologies. Advanced spectroscopic techniques that use neutrons and photons to probe these materials and processes can provide a wealth of information. Neutrons offer a unique ability to penetrate high-Z materials, such as uranium, when x-rays would not. This allows neutrons to be used for imaging on various high-Z materials including uranium fuel. Advanced neutron sources and detectors have enabled the development of spectroscopic neutron imaging techniques. These techniques can provide a wealth of imaging in 3D including isotopic/elemental content and crystallographic information. Recent work at Oak Ridge National Laboratory on developing spectroscopic neutron imaging techniques, such as neutron energy resonance imaging, to study nuclear materials (e.g., TRISO fuel materials) will be presented. Additionally, photons offer a unique ability to be moved large distances through optical elements such as optical fibers. This allows many optical spectroscopy techniques to be used remotely, even within high-radiation environments like a hot cell. Efforts at the Radiochemical Engineering Development Center to stand up various optical spectroscopic techniques to monitor radiochemical process in high-radiation environments will be discussed.
