“…[161]. In the fast energy range the data for n + 52 Cr were evaluated up to 150 MeV using the GNASH code while the data for n+ 50,53,54 Cr were evaluated with TALYS-1.0 up to 200 MeV using the geometry dependent hybrid pre-equilibrium model [162]. Particular attention was paid to reproducing the available experimental data for the total cross section and the (n,xn), (n,xp) and (n,xα) channels especially when these lead to radioactive residual nuclei [160].…”

“…The nuclear model simulations of the n + 63,65 Cu reactions were performed using the TALYS-1.8 code [43] for neutron energies between 1 keV and 200 MeV [199]. In spite of the general predictive power of TALYS, certain improvements can be gained by inclusion of an extra model for preequilibrium reactions, known as the Geometry Dependent Hybrid model (GDH) [162]. With the GDH model added to TALYS-1.8, the system provides more accurate results for n+Cu reactions compared to the existing models within the code.…”

The joint evaluated fission and fusion nuclear data library 3.3 is described. New evaluations for neutroninduced interactions with the major actinides 235 U, 238 U and 239 Pu, on 241 Am and 23 Na, 59 Ni, Cr, Cu, Zr, Cd, Hf, W, Au, Pb and Bi are presented. It includes new fission yields, prompt fission neutron spectra and average number of neutrons per fission. In addition, new data for radioactive decay, thermal neutron scattering, gamma-ray emission, neutron activation, delayed neutrons and displacement damage are presented. JEFF-3.3 was complemented by files from the TENDL project. The libraries for photon, proton, deuteron, triton, helion and alpha-particle induced reactions are from TENDL-2017. The demands for uncertainty quantification in modeling led to many new covariance data for the evaluations. A comparison between results from model calculations using the JEFF-3.3 library and those from benchmark experiments for criticality, delayed neutron yields, shielding and decay heat, reveals that JEFF-3.3 performes very well for a wide range of nuclear technology applications, in particular nuclear energy.

“…In this work we have used the special version of the code, TALYS v.1.95G [11], in which also the Geometry Dependent Hybrid model is implemented for the description of the preequilibrium process [12]. The best results have been obtained by performing considerations both from the numerical and physical points of view, with the goal of reaching a deeper comprehension of the underlying physics and going beyond the mere execution of the code.…”

Four terbium radionuclides (149Tb, 152Tb, 155Tb and 161Tb) are promising key players in the field of radiopharmaceutical production: in particular 155Tb emits Auger-electrons and γ rays suitable respectively for therapy and for SPECT imaging. In this work we investigate and compare two 155Tb generators by considering reactions of protons on natTb and of alpha particles on natGd for energies E<70 MeV. Both routes can be studied using intermediate energy cyclotrons for the production of 155Dy, the precursor of 155Tb. The two production routes are analyzed with the nuclear reaction code TALYS by varying the parameters of the models to improve the agreement between the calculated cross sections and the available experimental data. Realistic theoretical simulations for the production of 155Tb are performed by optimizing the activity and the purity of the final product, with a full simulation of the radiochemical separation procedure.

Abstract. The European approach for the development of nuclear data for fusion technology applications is presented. Related R&D activities are conducted by the Consortium on Nuclear Data Development and Analysis for Fusion to satisfy the nuclear data needs of the major projects including ITER, the Early Neutron Source (ENS) and DEMO. Recent achievements are presented in the area of nuclear data evaluations, benchmarking and validation, nuclear model improvements, and uncertainty assessments.
