Comparative evaluation of system characteristics such as system safety, economics, environmental burden reduction, etc. concerning candidate fuel fabrication systems are carrying out in the feasibility study on commercialized FBR cycle systems. In its phase II study, a study on characteristics evaluation techniques which focused attention on operating rate of the plant and waste generation started. In last fiscal year, the relationship between operating rate of the plant and waste generation amount was investigated in consideration of failure frequency and periodic replacement of equipments, and perspectives of characteristics comparison between multiple fuel fabrication systems were made clear. In this fiscal year, system characteristics evaluation of each low DF fuel fabrication system was conducted and characteristics comparison between those systems was carried out on the bases of perspectives which made clear last fiscal year. Plant design data obtained for each characteristics evaluation were linked to a database in order to make use of future system design investigation. In addition, system safety represented by operating rate and environmental burden reduction represented by waste generation were chosen as the intended characteristics in this study. In addition to this, programs of the characteristics evaluation simulator which designed until last fiscal year were modified in order to make more accurate calculation possible.
