The International Fusion Materials Irradiation Facility (IFMIF) is a neutron source aimed at producing an intense high energy neutron flux for testing candidate materials to be used in the fusion demonstration reactor. Engineering Validation and Engineering Design Activities (EVEDA) on IFMIF started under Broader Approach. As a major Japanese activity for Li target tasks of EVEDA, EVEDA Li Test Loop is under construction. Feasibility of hydraulic stability of the Li target and purification systems of hot traps is major key issues to be validated. Toward the validation at the loop, laboratory-scale tests and design for diagnostics to the high-speed free-surface Li target and the hot traps to control nitrogen and hydrogen in Li are carried out along with the construction of the loop. Regarding to progress of the construction, all major components except a target assembly are installed in a mount of the loop. The construction is scheduled to be finished on Feb. 2011.
