JAEA is now conducting Fast Reactor Cycle Technology Development (FaCT) project for the commercialization before 2050s. A demonstration reactor of Japan Sodium-cooled Fast Reactor (JSFR) is planned to start operation around 2025. In the FaCT project, conceptual design study on the demonstration reactor has been performed from 2007 to determine the referential reactor specifications for the next stage design work of the licensing and construction study. 750 MWe and 500 MWe plant designs are conducting to compare the plant performance as a demonstration reactor for the 1.5 GWe commercial reactor of JSFR. In this paper, current status of the conceptual design study of the demonstration reactor will be summarized.
