There is a problem that analysis work tends to become inefficient for lack of functionality suitable for analysis of composition change due to burnup since the conventional analysis system is targeted to critical assembly systems. Therefore development of burnup analysis system for fast reactors with modularity and flexibility can contribute actual core design work and improvement of prediction accuracy. In the previous study on "Development of Burnup Analysis System (for Fast Reactors)" in FY2005, basic design was conducted to define each component in the system(input, solver, edit) and how to drive them. In this study, detailed design of the system and implementation of the I/O component were conducted according to the results in the basic design followed by proto-typing implementation.
