“…The mechanistic understanding on the difference of the irradiation effects by fission-neutron, ion and electron irradiations will enhance accuracy of the prediction of D-T fusion neutron irradiation effects to be established based on the surrogate irradiation means. In this case, the validation of the prediction is foreseen by the irradiation facilities of neutrons whose spectrum closely resembles that of D-T fusion neutrons, such as IFMIF (International Fusion Materials Irradiation Facility) [16].…”

The evolution of interstitial dislocation loops in V-4Cr-4Ti during heavy ion and neutron irradiation was investigated in comparison with that during electron irradiation at temperature ranging from 407 K to 673 K. Temperature and damage rate dependence of the loop number density by heavy ion and neutron irradiations agreed well with those by electron irradiation obeying Sink and Recombination Dominant kinetics at low and high temperature, respectively. Heavy ion and neutron irradiations induced higher loop number density than that of electron irradiation at 563-673 K. The difference may be attributed to cascade-enhanced vacancy loop formation.

“…A schematic view of the A-FNS is given in Figure 3 5,13 . The A-FNS project plans to use an accelerator system to be established by the IFMIF/EVEDA Project which will be completed at the end of 2019 7 . The IFMIF/EVEDA accelerator system has a capability to accelerate deuterium ions to 9 MeV with a current of 125 mA.…”

This paper reports Japanese strategy for developing blanket structural materials for DEMO. In the Japanese program, the candidate materials are categorized into Primary Option (RAFM) and Advanced Options (V-alloy, SiC/SiC, ODS-RAFM etc.). A staged development is planned corresponding to the three decision-making points (DPs), DP1 : Intermediate check and review (C&R), DP2 : Decision of transition of research and development (R&D) focus to DEMO, and DP3 : Decision of DEMO construction. The near-term D-Li neutron source (A-FNS) and IFMIF are regarded as key facilities for the development. The strategy emphasizes "standardization" as an important step toward DEMO design qualification and licensing. The procedure to standard materials specifications by way of establishing structural design criteria and materials property requirements, and the procedure's interaction with the schedule of irradiation data acquisition are discussed.

“…Whereas the Engineering Validation Activity (EVA) phase has involved three major prototypes to validate the continuous operation of the facility: (1) the Linear IFMIF Prototype Accelerator (LIPAc) under installation in Rokkasho, the world highest beam average current linac; (2) the EVEDA Lithium Test Loop (ELTL) in operation in Oarai until November 2014, the world biggest liquid lithium loop; and (3) the High Flux Test Module constructed in KIT, cooled with He in the HELOKA loop (details of all the validation activities that is wider than the aforementioned major prototypes can be found elsewhere [21]), in turn the Engineering Design Activity (EDA) phase was successfully accomplished within the allocated time [22]. IFMIF [23] will consist of two 125 mA deuteron accelerators operating in CW (Continuous Wave, i.e. 100% duty cycle) and with a 200 mm × 50 mm beam cross section colliding on a 25 mm lithium screen flowing at 15 m/s with ±1 mm surface waves amplitudes, that will generate a neutron flux capable to provide >20 dpa per year to 1000 small specimens (whose feasibility has been also successfully demonstrated in the EVEDA phase) housed in 12 capsules independently cooled within T < 3%.…”
