Zusammenfassung:•China Nuclear Data Center developed China Evaluated Photonuclear Data Library CENDL/PD-b for nuclear engineering needs.•CENDL/PD-b contains 266 materials with photon incident energy range from photonuclear threshold energies to 200 MeV.•The nuclei in CENDL/PD-b are evaluated by the Chinese theoretical model codes to describe the experimental data available.•The global model parametersare applied to generate the photonuclear data, which exhibit good data systematic in physics.•For the first time this work systematically tests the CENDL/PD-b. This study generates the ACE-formatted library for the test edition of China Evaluated Photonuclear Data Library CENDL/PD-b by using NJOY2016, and verifies the applicability of the ACE-formatted library against the simple transport problem. This study also validates the performance of CENDL/PD-b on Barber and George benchmark, the photo-neutron yields of C, Al, Cu, Ta, and Pb targets were calculated by using the Monte Carlo code. The verification and benchmarking results show that CENDL/PD-b ACE-formatted library can be applied for Monte Carlo transport simulation, and the photo-neutron yields of C, Cu, Ta are in good agreement with the experimental values, all within the uncertainty of the experimental values. However, the photo-neutron yields of Al and Pb are lower than the experimental values, and more experimental validation for those photonuclear data are still needed in future.
