Development of High Temperature Molten Salt Transport Technology for Pyrometallurgical Reprocessing

摘要: Pyrometallurgical reprocessing technology is currently being focused in many countries for closing actinide fuel cycle because of its favorable economic potential and an intrinsic proliferation-resistant feature due to the inherent difficulty extracting weapons-usable plutonium. The feasibility pyrometallurgical has been demonstrated through laboratory scale experiments. Hence development engineering necessary a key issue industrial realization. high-temperature transport technologies molten salt liquid cadmium crucial processing; however, there have very few studies on fluids. In this study, test rig was installed argon glove box with aim developing transporting at approximately 773 K. gravitation K could be well controlled velocity from 0.1 1.2 m/s by adjusting valve. Consequently, flow can laminar turbulent flow. It that; using centrifugal pump, transported rate 2.5 8 dm3/min against 1 m head.
