“…An ADS consists of an accelerator, a spallation target and a subcritical reactor core [1,2]. Liquid lead-bismuth eutectic (LBE) is a possible target and coolant material due to its favourable nuclear, thermophysical and chemical properties [3,4]. In the target, radioactive and stable nuclides with masses up to one mass unit higher than the mass of the target components are generated by different proton induced nuclear reactions like for instance spallation and fission.…”

Abstract:The concentrations of the long-lived nuclear reaction products 129 I and 36 Cl have been measured in samples from the MEGAPIE liquid metal spallation target. Samples from the bulk target material (lead-bismuth eutectic, LBE), from the interface of the metal free surface with the cover gas, from LBE/steel interfaces and from noble metal absorber foils installed in the cover gas system were analysed using Accelerator Mass Spectrometry at the Laboratory of Ion beam Physics at ETH Zürich. The major part of 129 I and 36 Cl was found accumulated on the interfaces, particularly at the interface of LBE and the steel walls of the target container, while bulk LBE samples contain only a minor fraction of these nuclides. Both nuclides were also detected on the absorber foils to a certain extent (≪ 1% of the total amount). The latter number is negligible concerning the radio-hazard of the irradiated target material; however it indicates a certain affinity of the absorber foils for halogens, thus proving the principle of using noble metal foils for catching these volatile radionuclides. The total amounts of 129 I and 36 Cl in the target were estimated from the analytical data by averaging within the different groups of samples and summing up these averages over the total target. This estimation could account for about half of the amount of 129 I and 36 Cl predicted to be produced using nuclear physics modelling codes for both nuclides. The significance of the results and the associated uncertainties are discussed.

“…It has many advantages as a good spallation neutron target material, e.g., a very high yield of about 28 neutrons for every 1 GeV proton, an extremely small neutron absorption cross-section and very little moderation of neutrons. The drawbacks of LBE are: possible interactions between steels and LBE, which might lead to liquid metal embrittlement [4][5][6], production of polonium isotopes and volatile elements during irradiation that can give problems during reactor operation [7,8]. A physical phenomenon is the expansion of solidified LBE after freezing, which can give high stresses on the walls of a vessel [3][4][5].…”

“…Such facilities address horizontal technologies that could be of interest in other scientific areas, creating worthy synergies in the energy field. In particular, that is the case of liquid metals, that are planned to be used in Accelerator Driven Systems for transmutation of nuclear wastes, or Generation IV reactors [1][2][3].…”

The application of liquid metal technology in fusion devices requires R&D related to many phenomena: interaction between liquid metals and structural material as corrosion, erosion and passivation techniques; magneto-hydrodynamics; free surface fluid-dynamics and any other physical aspect that will be needed for their safe reliable operation. In particular, there is a significant shortage of experimental facilities dedicated to the development of the lithium technology. In the framework of the TECHNOFU-SION project, an experimental laboratory devoted to the lithium technology development is proposed, in order to shed some light in the path to IFMIF and the design of chamber's first wall and divertors. The conceptual design foresee a development in two stages, the first one consisting on a material testing loop. The second stage proposes the construction of a mock-up of the IFMIF target that will allow to assess the behaviour of a free-surface lithium target under vacuum conditions. In this paper, such conceptual design is addressed.
