YokomineDuring the Engineering Validation and Engineering Design Activities (EVEDA) phase of the International Fusion Materials Irradiation Facility (IFMIF), major elements of the Lithium Target Facility (the neutron source) and the Test Facility (implementing the irradiation experiments) were prototyped and tested. These works were successfullyconcluded in the frame of the Japanese and European Broader approach activities between 2007 – 20015.The validation activities included basic research (SSTT, corrosion), components (irradiation modules)  and large scalefacilities (lithium and helium loops). The results were fed back to the EVEDA design process and support the ongoingdesign activities towards an IFMIF plant to be realized timely, as necessary element of the fusion roadmaps.The Lithium Loop suppliesa constant flow of Li to thetarget. The ELTL loopoperated 519 days, startupand operation scenarios aswell as Li puritymeasurements wereperformed.The IFMIF plant overviewThe Lithium Target operates at 15m/s, 250°C. The long termstability of the lithiumflow thickness 25+/-1mm was proven byLaser probe measurements.HELOKA-LP is theprototype lowpressure heliumloop for coolantsupply of the testmodules.Prototypes of twoHigh Flux Test Module versionswere built. The irradiationtemperature range(HFTM-V: 250-550°C, HFTM-H: up to1000°C) andtemperaturehomogeneity was demonstrated.The Small Specimen Test Technique isessential for theIFMIF mission. Specimenshapes, testsetups and dataanalysis werefurther developed.Remote handlingoperations werevalidated for a 1:1 Target Assemblymockup.An irradiation in theBR2 reactor servedto test the irradiationcapsules, fissionchambers andCherenkov fiberoptics for thecharacterization ofthe IFMIF source.Li-corrosion tests ofRAFM steels underrelevant conditions(15m/s, <30 wppm N, 330°C) showed erosion<0.3µm/year
