Sumario:Nuclear data obtained in the neutron induced fission of $^{232}$Th nucleus are of great importance for advanced fast reactors based on Th fuel cycle. Fission cross sections, mass and charge distributions, prompt emission in fission including neutron multiplicities, yields and cross-sections of some isotopes of interest for applications, isomer ratios were obtained. This paper presents the theoretical predictions and the first results on $^{232}$Th(n,f) by applying Talys and the author’s computer code for modeling of nuclear reaction mechanisms and the fission process. Theoretical evaluations of fission observables and produced isotopes are compared with existing experimental data and with similar data for neutrons induced fission of $^{233}$U nucleus. The present researches on $^{232}$Th(n,f) reaction are realized in the frame of nuclear data program running at Joint Institute for Nuclear Research (Dubna) basic facilities, IREN, and MT-25 Microtron.
