The Facility for Rare Isotope Beams (FRIB) will be a new national user facility at Michigan State University (MSU) and funded by the Department of Energy Office of Science Office of Nuclear Physics (DOE-SC). FRIB will have the ability to accelerate uranium to 200 MeV/nucleon. Many long-lived, rare isotopes will be generated at FRIB that could potentially be harvested for off-line use. This study will use current conditions at the National Superconducting Cyclotron Laboratory (NSCL) to determine the production and extraction yields of four radioisotopes: 24Na, 67Cu, 48V, 85Kr. All of these radioisotopes will eventually be collected in an aqueous beam dump at FRIB. A water target apparatus has been constructed at Hope College that replicates the collection of isotopes in an aqueous beam dump. Modeling of the nuclear reactions at NSCL and subsequent decay products was done using two programs, LISE++ and Nucleonica. The information from these programs is being used to streamline the isolation and extraction procedures for the radioisotopes of interest from the aqueous beam dump at FRIB. 24Na and 67Cu have already been successfully harvested using a purified beam (~75% 67Cu) at the NSCL. Preliminary results from a revised extraction procedure and end station modifications will be presented to describe the successful harvesting at the NSCL from a more intense, less purified beam (~3% 67Cu).
