Stevens, J.I. ed.

The progress of extensive pilot-plant work on the fluidized-bed process for the conversion of radioactive liquid wastes to solids and the progress of construction of a 60-gal/hr demonstrational facility are reported. Pilotplant studies for the reporting period were directed toward establishing opemability limits for a 2-ft-square calciner and determining basic data on the dynamics of fluidized beds, such as particle attrition rates and heat-transfer rate. A short run in a 6-iu.-diameter calciner using a simulated stainless-steel waste indicated no problems that could be attributed to the composition of the feed, when these results were compared with the results of calcining aluminum type wastes. Data for the leaching of cesium from calcined alumina were assembled from vanious sources. From these data it is shown that a dilute nitric acid leach can remove 99.99% of the cesium in less than eight theoretical stages. Also, the leaching of cesium is more difficult from alumina that was calcined at 650DEC than from that calcined at 4O0DEC. Construction of a 60-gal/hr facility for the demonstration of the fluidized-bed technique with alumina type wastes was approximately 88% complete and the completion date was estimated to be mid-July 1960. First, extraction-cycle waste storage tanks were sampled and then chemical and radiochemical analyses were beam. The results from one tank indicated a high degree of chemical homogeneity throughout the tank. A rate of temperature rise curve was established for one waste tank and the heat generation rate was estimated. (For preceding period see IDO-14526.) (auth)
