Carlstrom, R F

The primary objective of the final cesium purification process is to produce a cesium carbonate product suitable for the encapsulation process. The encapsulation specifications are designed to minimize the volume of material to be encapsulated and control corrosion rates by assuring that the salt remains in the solid form. The feed for the cesium purification process is transferred from storage in Cell 37 to Cell 38. The feed is diluted with demineralized water and is loaded onto the ion exchange bed. The impurity cations (sodium, potassium, and rubidium) are removed (scrubbed) from the bed with a dilute ammonium carbonate-ammonium hydroxide solution passed through the bed in the same flow direction as the loading step. The cesium is removed from the ion exchange bed with a concentrated ammonium carbonate-ammonium hydroxide solution passed counterflow through the bed and the resulting product is concentrated. The concentrated cesium product is transferred to storage as available feed for the cesium encapsulation process.
