Thermal scattering data processing and development of Thermc module

The incident energy of thermal neutron ranges from 110-5 eV to 5 eV, which is comparable to energy of thermal motion of nuclide in the reactor, the reactions between neutron and target have vastly different characteristic in this energy range. The considerable effect of chemical bond, crystal lattice structure and thermal motion need to be taken into account. Distinct theoretical and processing methods have to be employed for different materials to obtain thermal scattering data used for transport codes. Correlative processing methods for thermal scattering data are introduced in this paper, Thermc module used for processing thermal scattering data was developed based on some of these methods. In addition, thermal scattering data result from Thermc module of RXSP and Thermr module of NJOY were compared in detail, macro examination was also carried out base on benchmark, results of comparison and examination demonstrate that data from Thermc are accurate.
