The University of Michigan, in collaboration with the Oak Ridge National Laboratory (ORNL), proposes to assess the feasibility of re-irradiating existing neutron irradiated alloys 304SS and 316SS to high dose levels using ion irradiation, for the purpose of achieving microstructures that represent those from reactor irradiation to those doses. The irradiation stage for ion irradiation will be prepared in the hot cell. The irradiations will focus on self-ion (Ni++) irradiation. Proton irradiation will be used for smaller dose increments.
