TL;DRAbstract

Various laboratory studies have been conducted in an effort to predict the behavior of fission product iodine in the EBR-II melt refining process.Both highly irradiated EBR-II-type fuel and uranium-fis slum alloys that had been spiked with iodine were used.When these materials were melt refined in lime-stabilized zirconia crucibles for one hour at 1400°C under an argon atmosphere, over 99% of the iodine was removed from the product ingot by volatilization.The volatilized iodine was collected primarily as Csl.These results confirmed earlier data obtained with unirradiated and low-activity-level fuel alloys, inasmuch as the iodine that had been volatilized during melt refining was not in the elemental form.''Gram-atom quantities of elements are baseo on perceniages found in the volatilized fraction and calculated concentrations in the fuel charge.c Uranium concentration was near the limit of detection for tne fluorophofometric techf'ique employed.*l Activities not detectable in the gamna
