Characterization of High Energy Xe Ion Irradiation Effects in Single Crystal Molybdenum with Depth Resolved Synchrotron Microbeam Diffraction

摘要

Heavy ion irradiation has long been used as an alternative to neutron irradiation to study irradiation effects in nuclear materials. Fission fragment induced irradiation damage is of great interest to nuclear fuel behaviors as it contributes to the majority of the damage done in the fuel materials. The formation and growth of fission gas bubbles in nuclear fuel materials and its implications are also of significant technical importance. The fuel swelling is strongly dependent on the evolution of fission gas bubble size and population.
