In this study, while examining the operating ratio which took into consideration the operation characteristics of apparatus for the low decontamination pelltizing method, and apparatus exchange frequency as the 2nd fiscal year of phase II of FBR cycle utilization strategy investigation research, the system characteristics evaluation simmulator was modified to able to calculate waste amount generated by fixed exchange of the parts. A comparison study of the operating ratio in a few other fabrication system was also performed by applying the simulator to them, and the following result was obtained. (1)While arranging the setting plan of operation characteristics of apparatus in connection with the apparatus operating ratio, optimization of the buffer capacity, throughput, and the number which improve operating ratio was performed. (2)The calculation program of waste amount generated which can respond to the case of fixed exchange of the parts, and the case parts of exchange at the time of failure was made. (3)The comparison method of the system characteristics among fabrication systems was considered, and comparison examination of operating ratio was performed by applying to the other fuel fabrication systems. (4)The simpler method for data input of the characteristic evaluation simulator manufactured in the last fiscal year was examined, and the simulator modification was carried out.
