Stabilizing simulated ICPP waste calcine in a 10-cm fluidized bed

Abstract
Alumina, zirconia, and zirconia-sodium blend calcines simulating those produced from nuclear reprocessing waste at the Idaho Chemical Processing Plant were denitrated in a 10-cm fluidized bed at temperatures up to 720/sup 0/C. Nitrates present in the calcines were reduced from 5.23 wt% to 0.5 wt% for zirconia-sodium calcine, from 0.17 wt% to < 0.1 wt% for zirconia calcine, and from 1.31 wt% to < 0.3 wt% for alumina calcine.
