dc.description.abstractThe study of neutron-induced reactions on actinides is of considerable importance for the design of advanced nuclear systems and alternative fuel cycles. Specifically, Th-230 is produced from the alpha-decay of U-234 as a byproduct of the Th-232/U-233 fuel cycle, thus the accurate knowledge of its fission cross section is strongly required. However, few experimental datasets exist in literature with large deviations among them, covering the energy range between 0.2 to 25 MeV. In addition, the study of the Th-230(n,f) cross-section is of great interest in the research on the fission process related to the structure of the fission barriers. Previous measurements have revealed a large resonance at E-n=715 keV and additional fine structures, but with high discrepancies among the cross-section values of these measurements. This contribution presents preliminary results of the Th-230(n,f) cross-section measurements at the CERN n_TOF facility. The high purity targets of the natural, but very rare isotope Th-230, were produced at JRC-Geel in Belgium. The measurements were performed at both experimental areas (EAR-1 and EAR-2) of the n_TOF facility, covering a very broad energy range from thermal up to at least 100 MeV. The experimental setup was based on Micromegas detectors with the U-235(n,f) and U-238(n,f) reaction cross-sections used as reference.es_ES
