Report of the working party on conversion of HIFAR to low enrichment uranium fuel.

This report states the effect on research reactor operations and applications of international and national political decisions relating to fuel enrichment. Technical work done in Australia and overseas to establish parameters for conversion of research reactors from High Enrichment Uranium (HEU) to Low Enrichment Uranium (LEU) have been considered in developing a strategy for HIFAR. The requirements of the research groups isotope production group and reactor operating staff have been considered. For HIFAR to continue to provide the required facilities in support of the national need it is concluded there should be no reduction of neutron flux
