The International Fusion Materials Irradiation Facility (IFMIF) is presently in its engineering validation and engineering design activities phase. The engineering design phase was successfully accomplished. The engineering validation activity has focused on validating the Accelerator Facility, the Target Facility and the Test Facility by constructing prototypes. The EVEDA Lithium Test Loop (ELTL) at JAEA successfully demonstrated the long-term stability of a Li flow under the IFMIF's nominal operational conditions keeping the specified free-surface fluctuations below 1 mm in a continuous manner for 25 days. A full-scale prototype of the high flux test module was successfully tested in the Helium Loop Karlsruhe (HELOKA), where it was demonstrated that the irradiation temperature can be set individually and kept uniform. LIPAc Accelerator, designed and constructed in European labs under the coordination of F4E and JAEA, presently under installation and commissioning in the Rokkasho Fusion Institute, aims at validating the concept of IFMIF accelerators with a D beam of 125 mA continuous wave and 9 MeV. The commissioning phases of the H/D beams at 100 keV were progressing and should be concluded in 2017; in turn, the commissioning of the 5 MeV beam was due to start during 2017. The D beam through the superconducting cavities is expected to be achieved with the superconducting cryomodule being assembled in Rokkasho.
