Minoru Takahashi1*1 Research Laboratory for Nuclear Reactors, Tokyo Institute of Technology, Tokyo, Japan*E-mail: mtakahas@nr.titech.ac.jp Thestatus and prospect of lead alloy-cooled fast reactor (LFR) have been explained for future development ofvarious types of LFRs that will be required for sustainable development of the world. Advantages of the LFRscompared with sodium-cooled fast reactors (SFR) are emphasized based on inherent safety features of the LFRs.Topics of research studies for the development of LFRs: compatibility of materials with lead alloy, oxygencontrol technique, etc., have been described referring recent studies. Long-term development plan and researchsubjects are described.Keywords: Lead, Lead-bismuth, Fast reactor, Neutronics, Material, Corrosion, Thermal-hydraulics, Safety
