The purpose of this work was to explore the use of fractional evaporative crystallization as a technology that can be used to separate medium-curie waste from the Hanford Site tank farms into a high-curie waste stream, which can be sent to a Waste Treatment and Immobilization Plant (WTP), and a low-curie waste stream, which can be sent to Bulk Vitrification. Experimental semi-batch crystallizations of sodium salts from simulant solutions of double-shell tank (DST) feed demonstrated that the recovered crystalline product met the purity requirement for exclusion of cesium and nearly met the requirement on sodium recovery. Batch fractional evaporative crystallization involves the removal of multiple solutes from a feed solution by the progressive achievement of supersaturation (through evaporation) and concomitant nucleation and growth of each species. The slurry collected from each of these crystallization stages was collected and introduced to filtration and washing steps. The product crystals obtained after washing were sampled for analysis by polarized light microscopy (PLM), dried, and sieved. The PLM results aided in identification of species crystallized in each stage. Carbonation was used as a supplemental method to evaporative crystallization in order to increase the sodium recovery in DST experiments. Carbonation was necessary due to the high aluminum ion concentration in the solution, which leads to formation of a viscous gel during evaporation. This gel was avoided by reacting carbon dioxide with hydroxyl ions, which modified the system behavior. Through two stages of carbonation, each followed by evaporation, the effect of carbonation on sodium recovery was demonstrated.

The scientific endeavors that took place at Hanford Engineer Works, beginning in World War II and continuing thereafter, are often overlooked in the literature on the Manhattan Project, the Atomic Energy Commission, and in regional histories. To historians of science, Hanford is described as an industrial facility that illustrates the perceived differences between academic scientists on the one hand and industrial scientists and engineers on the other. To historians of the West such as Gerald Nash, Richard White, and Patricia Limerick, Hanford has functioned as an example of the West's transformation during in World War II, the role of science in this transformation, and the recurring impacts of industrialization on the western landscape. This thesis describes the establishment and gradual expansion of a multi-disciplinary research program at Hanford whose purpose was to assess and manage the biological and environmental effects of plutonium production. By drawing attention to biological research, an area in which Hanford scientists gained distinction by the mid 1950s, this study explains the relative obscurity of Hanford's scientific research in relation to the prominent, physics-dominated national laboratories of the Atomic Energy Commission. By the mid 1960s, with growing public concern over radiation exposure and changes in the government's funding patterns for science, Hanford's ecologically relevant research provided a recognizable and valuable identity for the newly independent, regionally-based research laboratory. With funding shifts favoring the biological and environmental sciences in the latter half of the twentieth-century, Hanford scientists were well prepared to take advantage of expanding opportunities to carve out a permanent niche on the border of American science. / Graduation date: 2003
