Gibbsite/Bayerite and Uranium in Tank 41H
A brainstorming session was held on September 10, 2002 to discuss the issue of the aluminum trihydroxide phase (gibbsite and/or bayerite) separation from uranium in Tank 41H inhibited-water-insoluble solids. If a Nuclear Criticality Safety Evaluation (NCSE) for salt dissolution is to credit the hydrogen atoms in aluminum trihydroxide for moderation, an assessment is needed to evaluate if conditions during salt dissolution, and preferably during heel removal, could adversely affect the moderating effects of gibbsite/bayerite with respect to uranium phases. This report outlines the potential mechanisms for the chemical and physical separation of gibbsite from that of uranium in the insoluble solids in Tank 41H.
