Celebration of Learning
The structure of very unstable atomic nuclides are still not completely understood. The unstable atomic nuclides in this study emit a neutron, which requires determining the energy of decay to better understand the structure. The energy of decay may be calculated from the energy and momentum of the remaining charged fragment and neutron. From the calculated decay energy, information about an isotope’s nuclear structure can be found. At the National Superconducting Cyclotron Laboratory experiment, a 27Ne ion beam hit a liquid deuterium target that resulted in many produced atomic nuclides. One of the isotopes produced was unstable 26F, …

This work aims to verify the correct implementation of an anisotropic grain boundary (GB) energy model for face-centered cubic (FCC) and fluorite materials in Idaho National Laboratory’s phase field fuel performance code MARMOT. The model was recently implemented in MARMOT with the purpose of enabling higher fidelity simulations of UO2 nuclear fuels. As part of verification, tests were performed to measure the energy dependence on misorientation of high symmetry GBs in an FCC metal (Cu). The energies of the [100], [110], and [111] twist boundaries result as predicted, as do the energies of the [111] symmetric tilt boundaries. However, …
