“…These are, in particular: The Linear IFMIF Prototype Accelerator (LIPAc) which is presentlyunder commissioning at Rokkasho, Japan, cloning the IFMIF components up to its first superconductive accelerating stage (9 MeV, 125 mA of D+ beam in CW operation). Tiered-commissioning of the accelerator systems started in November 2014 and is planned to be completed by integral commissioning and long-pulsed operational testing in the next few years [ 42 ]; The Experimental Lithium Test Loop (ELTL) built at Oarai, Japan [ 43 ], integrating all the elements of the IFMIF lithium target facility. It was commissioned in February 2011 and the test programme was completed in 2014 with the successful proof of the long-time stability of the liquid lithium jet forming the target [ 40 , 44 ], complemented by corrosion experiments performed on the Lifus 6 lithium loop constructed at ENEA Brasimone Research Centre in Italy [ 45 ]; The HFTM prototype along with a prototype of the specimen capsules.…”

International Fusion Materials Irradiation Facility-DEMO-Oriented NEutron Source (IFMIF-DONES) is a high-intensity neutron irradiation facility for qualification of fusion reactor materials, which is being designed as part of the European roadmap to fusion-generated electricity. Its main purpose is to study the behavior of materials properties under irradiation in a neutron flux able to simulate the same effects in terms of relevant nuclear responses as those expected in the first wall of the DEMO reactor which is envisaged to follow ITER. It is thus a key facility to support the design, licensing and safe operation of DEMO as well as of the fusion power plants that will be developed afterwards. The start of its construction is foreseen in the next few years. In this contribution, an overview of the IFMIF-DONES neutron source is presented together with a snapshot of the current engineering design status and of the relevant key results achieved within the EUROfusion Work Package Early Neutron Source (WPENS) as part of the 2014–2020 EURATOM Research and Training Programme, complementary to the EU Horizon 2020 Framework Programme (FP8). Moreover, some information on the future developments of the project are given.

“…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].…”

“…To validate the operational conditions of IFMIF’s Target Facility, a lithium loop was constructed in the JAEA premises of Oarai as one of the validation activities under EVEDA phase [8], the EVEDA Lithium Test Loop (ELTL), which started its operation in March 2011 [22]. Unfortunately, the Great East Japan Earthquake damaged the ELTL just few days after its successful commissioning; thus the operation was suspended for 16 months to allow for a careful inspection and repair.…”

The flowing lithium target of a Li(d,xn) fusion relevant neutron source must evacuate the deuteron beam power and generate in a stable manner a flux of neutrons with a broad peak at 14 MeV capable to cause similar phenomena as would undergo the structural materials of plasma facing components of a DEMO like reactors. Whereas the physics of the beam-target interaction are understood and the stability of the lithium screen flowing at the nominal conditions of IFMIF (25 mm thick screen with +/–1 mm surface amplitudes flowing at 15 m/s and 523 K) has been demonstrated, a conclusive assessment of the evaporation and condensation of lithium during operation was missing. First attempts to determine evaporation rates started by Hertz in 1882 and have since been subject of continuous efforts driven by its practical importance; however intense surface evaporation is essentially a non-equilibrium process with its inherent theoretical difficulties. Hertz-Knudsen-Langmuir (HKL) equation with Schrage’s ‘accommodation factor’ η = 1.66 provide excellent agreement with experiments for weak evaporation under certain conditions, which are present during a Li(d,xn) facility operation. An assessment of the impact under the known operational conditions for IFMIF (574 K and 10−3Pa on the free surface), with the sticking probability of 1 inherent to a hot lithium gas contained in room temperature steel walls, is carried out. An explanation of the main physical concepts to adequately place needed assumptions is included.
