This paper argues the characteristics evaluation of Fast Reactor and fuel cycle concepts in the FS "Feasibility Study on commercialized fast reactor cycle systems" and the achievement of the performance evaluation conducted in FaCT (Fast Reactor Cycle System Technology Development) project in Japan. The methodologies and way of achievement evaluation has been changed according to the evaluation needs and objectives, etc. Some decision-making methodologies are tried to be applied in the FS, FaCT phase I evaluation put emphasis on the confirmation of the direction of FR cycle development. Although some items of respective facilities showed insufficient achievements because of the challenging design requirements to achieve higher performance, a comprehensive evaluation determined that the performance criteria set by the Japan Atomic Energy Commission were achieved in FaCT phase I evaluation in general.
