3. DESCRIPTION OF FUNCTION
Contains Th-232 neutron interaction cross sections in the energy range below 20 MeV, evaluated starting from both recent experimental data and theoretical results obtained by using updated versions of the CIRCE, POLIFEMO and PENELOPE chain of codes for direct reaction, compound nucleus and direct scattering calculations. The angular distributions for inelastic scattering by the first three excited levels, taking into account the nuclear deformation up to the hexadecapole term, have been calculated and compared with experimental results. The data are provided for MCNP codes.
FORMAT: ACE
GROUP STRUCTURE: Continuous energy
NUCLIDE: Th-232
TEMPERATURE: 300 K

4. METHODS
The new data set has been tested in calculations performed on the THOR fast criticality experiment. The transport calculations were carried out in spherical geometry through the XSDRNPM transport module of the SCAMPI Data Processing System. The results were compared with the corresponding ones obtained with other Th data files (ENDFB VI-3, JEF-2.2 and JENDL-3.2).
