Evaluation of neutron cross-sections for fission product nuclei in the energy range up to 50 MeV

In this paper, the neutron cross-sections for unstable fission product nuclei for neutron energies up to 50 MeV are evaluated. These long-lived fission products have high yields and therefore constitute a complex problem in the fuel reprocessing cycle. The evaluation is based on the calculations of reaction cross-sections applying the statistical nuclear reaction model taking into account the pre-equilibrium mechanism and using the ALICE-87 code. The comparison, wherever possible, with the available experimental data proved that these results can serve as initial data for different kinds of calculations on environmental aspects of the utilization of radioactive waste and its transmutation.
