Prediction of the cross-sections of isotopes produced in deuteron-induced spallation of long-lived fission products *

Abstract

The spallation cross-section data for the long-lived fission products (LLFPs) are scarce but required for the design of accelerator driven systems. In this paper, the isospin dependent quantum molecular dynamics model and the statistical code GEMINI are applied to simulate deuteron-induced spallation in the energy region of GeV/nucleon. By comparing the calculations with the experimental data, the applicability of the model is verified. The model is then applied to simulate the spallation of 90Sr, 93Zr, 107Pd, and 137Cs induced by deuterons at 200, 500 and 1000 MeV/nucleon. The cross-sections of isotopes, the cross-sections of long-lived nuclei, and the reaction energy are presented. Using the above observables, the feasibility of LLFP transmutation by spallation is discussed.

“…On the other hand, data of the neutron-induced spallation are still required in the study of fast reactors and accelerator driven sub-critical systems (ADS) [29,30]. In addition, these data are still very limited at present because of the difficulty to obtain neutrons in the GeV region and the impossibility of inverse dynamics [31][32][33].…”
