Development of Transport Technologies for High-temperature Fluid in Pyrometallurgical Reprocessing

The development of the engineering technology necessary for pyrometallurgical reprocessing is a key issue for industrial realization. The development of high-temperature transport technologies for molten salt and liquid cadmium is crucial for pyrometallurgical processing; however, there have been very few transport studies on high- temperature fluids. In CRIEPI, the transport technologies of molten salt and liquid cadmium have been developed for several types of transports methods. Based on the results of transport tests, engineering scale process equipments connected each other with the transport technology have been developed, and installed in the Ar atmosphere glove box for integrated tests.
