Nuclear supply chain and SCM code Figure 3 shows the relationship between the facilities in nuclear fleet. For example the effects from the differences of breeding ratio of FR reprocessing plant and Am-Cm recycling on characteristics from developmental targets influences the material flow from reprocessing plant. With the object oriented design feature and mechanism that conveys information and materials via the interface among highly independent facilities it is easy to place improvements on a facility by itself according to needs. Furthermore the SCM code enabled us to simulate nuclear fuel cycle overall in the process of procurement dispose and transportation of material from the upper to lower facilities without any major change with facility data that indicates basic characteristics of nuclear facilities according to the provided schemes and scenarios as the assumption of analyses by user in timely manners. 3. Characteristics evaluation of equilibrium FR cycle and scenario evaluation In this section evaluation on Japanese nuclear fleet in FaCT project is described mainly by SCM code code. It covers almost all the facilities in Japan from the beginning of the nuclear energy utilization and FR cycle equilibrium state in far future. Characteristics evaluation of equilibrium FR
