Operations of a dry reprocessing plant are characterized by batch processing with remote-control material handling machines, so plant -wise simulation of their mechanical actions is required to evaluate the overall performance of the plant. Therefore a simulator has been developed using virtual engineering techniques. The results performed in JFY 2001 are as follows: (1)Construction of an operation simulator of a dry-reprocessing plant design. An operation simulator was developed based on the preliminarily conceptual design of the oxide-electrowinning reprocessing plant made at the phase one of the Feasibility Study on Commercialized Fast Reactor Cycle Systems. The simulator is able to correspond changes of the plant design in future. (2)Evaluation of the oxide-electrowinning reprocessing plant design Simulation was performed using the simulator of the preliminarily conceptual design of the oxide-electrowinning reprocessing plant. The results show that the capacity of the plant will be much lower than the designed one (50tHM/y) due to the speed of material handling machines. The results of the parametric survey of gripping and fixing time also show that the plant capacity can attain 94% of the required capacity even if the gripping and the fixing time decrease to zero. This indicates that only increasing the speed is not enough to dissolve the problem.
