DEVELOPMENT OF COMPAS, COMPUTER-AIDED PROCESS FLOWSHEET DESIGN AND ANALYSIS SYSTEM OF NUCLEAR-FUEL REPROCESSING

A computer aided process flowsheet design and analysis system, COMPAS has been developed in order to carry out the flowsheet calculation on the process flow diagram of nuclear fuel reprocessing. All of equipmen ts, such as dissolver, mixer-settler, and so on, in the process flowsh eet diagram are graphically visualized as icon on a bitmap display of UNIX workstation. Drawing of a flowsheet can be carried out easily by the mouse operation. Not only a published numerical simulation code bu t also a user's original one can be used on the COMPAS. Specifications of the equipment and the concentration of components in the stream di splayed as tables can be edited by a computer user. Results of calcula tion can be also displayed graphically. Two examples show that the COM PAS is applicable to decide operating conditions of Purex process and to analyze extraction behavior in a mixer-settler extractor.
