Theoretical assessment and targeted modeling of TiO in reactor towards the scandium radioisotopes estimation.

Sc radioisotope with beta particle emission can be used for targeted radionuclide therapy in nuclear medicine and can be produced by nuclear reactor (with high activities) and accelerator. In this work, the specific activity of Sc with the isotopic impurities produced through irradiating the enriched Tio and natural TiO targets have been calculated by the MCNPX-2.6 and the TALYS-1.8 codes and also theoretical approach in a fast neutron flux 3×10ncms in the reactor. In addition, the cross sections of Ti(n,p)Sc reaction have been interpolated in the 1-10MeV energy range and compared with the corresponding experimental data, as well. Moreover, the average cross sections of Ti(n,p)Sc, Ti(n,p)Sc and Ti(n,p)Sc reactions were reproduced. Acceptable agreement between the experimental data and calculated results confirms the ability of the used methods to design and predict the production process in reactor.
