IFMIF Lithium Target Facility Design

Abstract: The Lithium target provides the neutrons for the irradiation of test specimens to generate property data for future fusion reactor materials. The (d,xn)-stripping reaction of 40 MeV deuterons was found to yield a spectrum representative of the fusion spectrum and a beam current of 250 mA a flux to create a damage rate similar to the first wall of future reactors. The beam power of 10 MW can only be mastered by a window-less liquid metal target in the cross-flow mode. The liquid metal is conducted in a concave shaped open channel past the beam. The concept imposes severe constraints with respect to flow stability and Lithium evaporation. The direct exposure to the accelerator vacuum affords a non-pressurized circulation loop and hence a specific layout. The IFMIF/EVEDA Project within the Broader Approach Agreement between the European Union and Japan is supposed to provide a detailed design of the irradiation facility and all necessary information for site selection and tendering for the construction. The design of the Lithium target facility is a joint undertaking of JAEA and ENEA supported by experimental validation of key issues relevant for a sound design. After a long preparation period, the design work has now started. The presentation will give an overview of the current status and organization of work. It will describe the design baseline and outline design rules for some of the key issues. Design details will also be compared to those in the EVEDA Li Test Loop, which has been built and commissioned in Japan within this project.
