“…In addition, NRT dpa do not take into account the time-evolution of radiation damage in the materials, such as recombination, migration, and coalescence of radiation defects, and in this sense they represent an atom-based approximate measure of the irradiation exposure of the material to the fusion neutrons. The generation of He and H from transmuted elements together with displacement effects in the materials lattice under fusion-like neutron bombardement has inherent uncertainties on the effects on mechanical and physical properties that can only be overcome through testing in as close as possible conditions [2]. IFMIF, the International Fusion Materials Irradiation Facility, will generate a neutron flux with a peak at around 14 MeV by (d,Li) stripping reactions thanks to two parallel deuteron accelerators colliding in a liquid Li screen with a footprint of 20 cm x 5 cm.…”

Abstract. The Engineering Validation and Engineering Design Activities (EVEDA) for the International Fusion Materials Irradiation Facility (IFMIF), an international collaboration under the Broader Approach Agreement between Japan Government and EURATOM, aims at allowing a rapid construction phase of IFMIF in due time with an understanding of cost involved. The three main facilities of IFMIF: 1) the Accelerator facility, 2) the Target facility and 3) the Test facility are the subject of validation activities that include the construction of either full scale prototypes or smartly devised scaled down facilities that will allow a straightforward extrapolation to IFMIF needs. By July 2013, the engineering design activities of IFMIF matured with the delivery of an Intermediate IFMIF Engineering Design Report (IIEDR) supported by experimental results. The installation of a Linac of 1.125 MW (125 mA and 9 MeV) of deuterons started in March 2013 in Rokkasho (Japan). The world largest liquid Li test loop is running in Oarai (Japan) with an ambitious experimental programme for the years ahead. A full scale High Flux Test Module that will house ~1000 small specimens developed jointly in Europe and Japan for the Fusion programme has been constructed by KIT (Karlsruhe) together with its He gas cooling loop. A full scale Medium Flux Test Module to carry out on-line creep measurement has been constructed by CRPP (Villigen).

“…Finally, it should be mentioned that new developments to produce intense neutrons with E n 12 MeV are in progress at the SPIRAL-2 project at GANIL in France, in which intense neutrons of about 10 14 n/(cm 2 s) are planned to be produced using a 40 MeV linear accelerator, 22) and at the SARAF project in Israel. 23) At the International Fusion Materials Irradiation Facility (IFMIF), 24) intense neutrons greater than 10 15 n/(cm 2 s) with the energy spectrum peaking at around 14 MeV could be produced by bombarding a liquid lithium jet target with intense deuteron beams of about 35 -40 MeV. At Lawrence Berkeley National Laboratory, a new ion source by employing RF-induced discharge is being developed to produce intense deuterium ions, and thereby to obtain intense neutrons of 10 13 n/s via 3 H(d; n) 4 He.…”

A Review of Dangerous Dust in Fusion Reactors: from Its Creation to Its Resuspension in Case of LOCA and LOVA

Abstract:The choice of materials for the future nuclear fusion reactors is a crucial issue. In the fusion reactors, the combination of very high temperatures, high radiation levels, intense production of transmuting elements and high thermomechanical loads requires very high-performance materials. Erosion of PFCs (Plasma Facing Components) determines their lifetime and generates a source of impurities (i.e., in-vessel tritium and dust inventories), which cool down and dilute the plasma. The resuspension of dust could be a consequences of LOss of Coolant Accidents (LOCA) and LOss of Vacuum Accidents (LOVA) and it can be dangerous because of dust radioactivity, toxicity, and capable of causing an explosion. These characteristics can jeopardize the plant safety and pose a serious threat to the operators. The purpose of this work is to determine the experimental and numerical steeps to develop a numerical model to predict the dust resuspension consequences in case of accidents through a comparison between the experimental results taken from campaigns carried out with STARDUST-U and the numerical simulation developed with CFD codes. The authors in this work will analyze the candidate materials for the future nuclear plants and the consequences of the resuspension of its dust in case of accidents through the experience with STARDUST-U.
