Production and testing of HENDL-2.1/CG coarse-group cross-section library based on ENDF/B-VII.0

Abstract A coarse-group coupled neutron and photon (27 n  + 21γ) cross-section library HENDL-2.1/CG, based on ENDF/B-VII.0 evaluate data source, has been produced by FDS Team in Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). HENDL-2.1/CG containing 350 nuclide cross-section files (from 1 H to 252 Cf) was generated in MATXS format with the NJOY processing system and then by compiling coarse-group problem-dependent format using the TRANSX code. In order to verify the availability and reliability of the HENDL-2.1/CG data library, requisite benchmark calculations were performed and compared with HENDL-2.0/MG fine-group coupled neutron and photon (175 n  + 42γ) cross-section library. In general, results using the coarse-group library showed similarly believable as fine-group library.
