Abstract: To research plutonium conversion process information on nuclear fuel recycle plant and compare the difference from intermittent and successive process, it is suggested that the successive process is better for the large nuclear fuel recycle plant in the future. There are strict requests to the equipments in successive process, for example throughput, stability, sealed identity and servicing based on it. According to the function and technologic requests, there is a preliminary plan about the key equipments, such as successive precipitator, the successive filtrator, the successive calcinator, the successive homogenizer and so on.
