Prospects for the recovery of uranium from seawater. Final report. [URPE]
A computer program entitled URPE (Uranium Recovery Performance and Economics) has been developed for analysis of a plant recovering uranium from seawater. The conceptual system design consists of a floating oil-rig type platform, using seawater forced through hydrous titanium oxide. Uranium is recovered from the seawater by adsorption and eluted later. The equilibrium isotherm and the diffusion constant for the uranyl-HTO system, which are needed for bed performance calculations, have been calculated. The URPE program has been benchmarked against previous studies by ORNL and Exxon, and found to make comparable performance and economic estimates. The URPE code was then used to identify optimum bed operating conditions. Thin beds of small, thinly-coated particles are the preferred bed configuration, and actively pumped systems outperform current driven units. Based on URPE, the minimum expected costs of uranium recovered from seawater would be no lower than approx. 316 (1979$)/lb U/sub 3/O/sub 8/ for state-of-the-art adsorber material (capacity equal to 210 mg U/kg Ti), but might be reduced to the level of breakeven attractiveness of approx. 150 (1979$)/lb U/sub 3/U/sub 8/ if at least a four-fold increase in adsorption capacity could be achieved.
