Production of 99Mo at the annular core research reactor-recent calculative results

Significant progress has been made over the past year in understanding the chemistry and processing challenges associated with 99Mo production using Cintichem-type targets. Targets fabricated at Los Alamos National Laboratory have been successfully irradiated in fuel element locations at the Annular Core Research Reactor (ACRR) and processed at the Sandia Hot Cell Facility. The next goal for the project is to remove the central cavity experiment tube from the reactor core, allowing for the irradiation of up to 37 targets. After the in-core work is complete, the reactor will be capable of producing significant quantities of 99Mo
