Abstract
Candidate high-temperature gas-cooled reactor fissile and fertile particles were irradiated in the High Flux Isotope Reactor removable beryllium reflector facility (RB-5) for eight reactor cycles. The experiment contained 18 different ''types'' of fissile particles and five different ''types'' of fertile particles. All uranium was 20% enriched in /sup 235/U. The loose particles were loaded into ''trays'' that resemble flat graphite washers, each having 116 drilled holes in one face. One hundred eighty-four trays were stacked in columns in an alternate fertile particle-fissile particle sequence. The particles were irradiated for 169.4 full power days. The report discusses methods used to specify particle loadings and contains thermal and neutronics results applicable to the irradiation test period.Keywords
