“…In order to improve the calculation of the d-Li neutron source term of IFMIF, an analysis of the elastic-scattering angular distributions of deuterons on 6,7 Li, for energies from 3 up to 50 MeV, using a phenomenological optical model potential (OMP) [29] was involved within an updated d+ 6,7 Li data evaluation [30,31]. The OMP analysis was completed by the coupled reaction channels (CRC) method within the code FRESCO [32] for consideration of the elastic transfer additional mechanism [33].…”

“…Also in connection with the IFMIF project, Ye et al analyzed in Ref. [34] the deuteron elastic scattering from 6,7 Li in the energy range from 10 to 50 MeV by the continuum discretized coupled channels (CDCC) method ( [35] and Refs. therein).…”

“…The design analyses of the high intensity accelerator-based neutron source International Fusion Materials Irradiation Facility (IFMIF) [1], for ITER fusion device [2] and European DEMO fusion reactor [3] material qualification, require also high-quality cross-section data of deuteron induced reactions. Related activities are currently conducted within the Power Plant Physics and Technology (PPPT) programme of the EUROfusion Consortium [4], following a previous partnership agreement of Fusion for Energy (F4E) [5] with the Consortium on Nuclear Data Development and Analysis [6]. A sub-library of the latest version 3.2 [7] of Fusion Evaluated Nuclear Data Library (FENDL) [8], developed at IAEA/NDS, is going to include the most recent corresponda e-mail: marilena.avrigeanu@nipne.ro (corresponding author) b e-mail: dimitri-alexandre.rochman@psi.ch c e-mail: a.koning@iaea.org ing results, while there is a world-wide use of the deuteron sub-library of the current TENDL-2019 evaluated nuclear data library [9] based on the output of the TALYS nuclear model code system [10] for direct use in both basic research and applications.…”

Following the EUROfusion PPPT-programme action for an advanced modeling approach of deuteron-induced reaction cross sections, as well as specific data evaluations in addition of the TENDL files, an assessment of the details and corresponding outcome for the latter option of TALYS for the breakup model has been carried out. The breakup enhancement obtained in the meantime within computer code TALYS, by using the evaluated nucleon-induced reaction data of TENDL-2019, is particularly concerned. Discussion of the corresponding results, for deuteron-induced reactions on $$^{58}$$ 58 Ni, $$^{96}$$ 96 Zr, and $$^{231}$$ 231 Pa target nuclei up to 200 MeV incident energy, includes limitations still existing with reference to the direct-reaction account.

“…The development of nuclear data for fusion technology in Europe has been previously organized by Fusion for Energy (F4E), Barcelona, through a framework partnership agreement with the Consortium on Nuclear Data De-velopment and Analysis [2]]. The related activities addressed the nuclear data needs of the key facilities ITER, IFMIF and DEMO and included the evaluation and validation of relevant nuclear cross-section data, the development/extension of codes and software tools required for nuclear model calculations and sensitivity/uncertainty assessments.…”

The activities of the EUROfusion consortiums on the development of high quality nuclear data for fusion applications are presented. The activities, implemented in the Power Plant Physics and Technology (PPPT) programme of EUROfusion, include nuclear data evaluations for neutron and deuteron induced reactions and the production of related data libraries which satisfy the needs for nuclear analyses of the DEMO fusion power plant and the IFMIF-DONES neutron source. The activities are closely linked to the JEFF initiative of the NEA Data Bank. The evaluation work is complemented by extensive benchmark, sensitivity and uncertainty analyses to check the performance of the evaluated cross-section data and libraries against integral experiments.

Analysis of the latest high–precision cross sections of (α,γ) and (α,n) reactions on 144Sm below the Coulomb barrier is carried out using a consistent parameter set of the statistical model. This prevents the need to use empirical rescaling factors of either γ or neutron widths. Particular attention is paid to uncertainties of the calculated cross sections which are related to the accuracy of the primary data that were used to set up the consistent input parameters. The calculated cross sections are found in good agreement with the new experimental data for the 144Sm(α,n)147Gd reaction; however, the same is not true for the excitation function of 144Sm(α,γ)148Gd which decreases faster at incident energies below ∼12 MeV. An increase of the α-particle direct collective inelastic scattering at lower energies is found responsible for this decrease of the (α,γ) reaction cross sections. The consequent lower nuclear effects may correspond to the Coulomb excitation effect assumed, although in a different manner, within the so-called “α-potential mystery” for the same optical–potential account of α-particle absorption and emission as well.
