The prototype fast breeder reactor MONJU resumed the System Startup Test (SST) on May 6th 2010 after five months and fourteen years shutdown since the sodium leakage of the secondary heat transport system on December 1995. Core Confirmation Test (CCT) is the first step of SST, which consists of three steps. CCT was finished on July 22nd after 78 days tests. CCT is composed 20 test items including control rods' worth evaluation, radiation dose measurement etc..

Successful introduction scenarios into the practical application of FBR cycle have been investigated taking into account not only a domestic view point but also a worldwide view point. Considerations are paid on the discrimination between the influence factors that lead to the nuclear power introduction and those that lead to the FBR cycle introduction. The economic competitiveness is one of the most important factors along with the limitation for the CO release. Five major scenarios have been induced on view points of economy, reduction of radioactive waste, utilization of small scale FBRs, and Iimitation of uranium resource.
