The ACE photon data library used in MCNP 6.2 by default (MCPLIB84) cannot be directly converted to HDF5 with openmc.data. Therefore, it is currently not possible to employ the same photon data library in OpenMC as the one that was used to run the MCNP benchmark simulations.
The generation pipelines of HDF5 data libraries that we currently use, fetch ENDF photon data from the official nuclear data webpages.
Additionally, the HDF5 photon data files from FENDL 3.2c (https://nds.iaea.org/fendl/data/atom/) are not compatible with OpenMC 0.15.3, which forced us to use a different photon data library even when using FENDL 3.2c for neutron cross sections.
All the differences between the photon data used for OpenMC or MCNP simulations, or even for a fixed transport code, between 2 different runs of the same benchmark (depending on the code version), should be somehow documented.
Describe the solution you'd like
The photon data library used in each simulation should be documented. An addition to the metadata could be the best place to record it.
