“…IFMIF presents three technological challenges that the EVEDA phase aims to overcome: (1) the Accelerator Facility, (2) the Target Facility, and (3) the Test Facility. Three major prototypes have been designed and are either presently operating or being manufactured: (1) an Accelerator Prototype (LIPAc) at Rokkasho, cloning those of IFMIF up to its first superconductive accelerating stage (9 MeV energy, 125 mA of D + continuous wave current) to be completed in June 2017 [22]; (2) a Li Test Loop (ELTL) at Oarai, integrating all elements of the IFMIF Li Target Facility, commissioned in February 2011 [23], complemented by corrosion experiments performed at a Li loop (Lifus6) in Brasimone [24]; and (3) the High Flux Test Module (two different designs to accommodate either RAFM or SiC) [25,26] with a prototype of the capsules housing the small specimens to be irradiated in the BR2 fission reactor of SCK/CEN Mol [27] and tested in the cooling helium loop HELOKA of KIT, Karlsruhe [28]; complemented with the Creep Fatigue Test Module [29] manufactured and tested in full scale at PSI, Villigen. The validation activities and its most recent status have been described elsewhere [20][21][22].…”
