An experimental physics-neutronics study of materials and design concepts for proposed high-temperature fast reactors has been undertaken in support of the Argonne National Laboratory rocket-design effort. In the basic design, the fuel is highly enriched U²³⁵, the major diluent is a tungsten rhenium alloy, and the reflector material is a light metal or metal oxide. Initial studies have concerned specifically tungsten as a diluent in moderate volume (100- to 300-liter) fast-reactor cores and aluminum as the reflector. This report summarizes the results of measurements made on four fast critical experiments performed in ZPR-9. A major objective of these experiments was to provide the necessary data for selection of a single, multigroup, tungsten cross-section set from the several generated for this program.
