Status of Activities on the Lithium Target Activities in Key Element Technology Phase of IFMIF

This paper describes the status of liquid lithium (Li) target facility in Key Element technology Phase (KEP) of International Fusion Materials Irradiation Facility (IFMIF). The IFMIF is being jointly developed by European Union (EU), Japan (JA), Russian Federation (RF) and US to provide an accelerator-based D-Li neutron source for testing the candidate materials for fusion reactor. Key issue of the Li target is to obtain a stable liquid Li flow with a speed of 20 m/s under a deuterium beam deposition of 10 MW. In the KEP, 19 tasks for the Li target are proposed and shared by EU, JA and RF. These tasks are Li flow experiment, Li simulation experiment by water jet, corrosion/erosion, remote handling, and safety analysis. In addition to the KEP tasks, detailed design of the target is being performed on transient thermal analysis of the Li , remote handling of the target assembly and safety analysis of the Li loop.
