In order to generate a multi-group constant library NuDa-SN for the 3D discrete ordinate (SN) transport program JSNT-S developed in CAEP Software Center for High Performance Numerical Simulation, a basic line of master library cooperating with work library was put forward. Based on the ENDF/B-Ⅶ.1, a master library was generated with NJOY2016 and CMiler codes. 455 nuclides are included in this master library which collapsed into 199 neutron energy groups and 42 photon energy groups. In order to verify the reliability of this master library, unit test, criticality benchmark test and shield benchmark test were carried out respectively. All the tests show that this master library can be used reliably in the criticality calculation and shielding calculation.

Key words: NuDa-SN, multi-group constant library, master library, benchmark test
