The evaluation of neutron resonance parameters for Th-232 in the energy region from 0 to 200 eV

The thorium fuel cycle has been recently interested as an alternative fuel option in the aspect of non-proliferation. Therefore, more accurate nuclear data of the thorium became necessitated to support the research activities in the area of reactor physics and design on the reactor which uses the thorium as a fuel. In this study, neutron resonance parameters of Th-232 are evaluated using the weight average method, the Portor-Thomas distribution and the Bayesian approach in the energy region from 0 to 200 eV. It is shown that the evaluated capture and scattering cross sections in the thermal energy region are well agreed with ENDF/B-VI, JENDL-3. JEF-2 and CENDL-2 data. Also, the orbital angular momentum, spin and neutron strength function are assigned and the resonance parameters such as neutron widths, gamma widths and energy are prepared in the format of ENDF file
