For anyone using the official data libraries for OpenMC — there was an error with these data libraries for some nuclides at temperatures of 600 K or higher due to a bug in NJOY. For full details, please see this issue. These data libraries have been regenerated with the latest version of NJOY in which the bug was fixed and I’ve uploaded them to openmc.org; we recommend redownloading the libraries for your use.
Many thanks for the updated library. Have you regenerated all ENDF/B-VII.1, VIII.0 and JEFF3.3?
@Jiankai Yes, each of the official libraries (ENDF/B-VII.1, ENDF/B-VIII.0, and JEFF 3.3) has been regenerated.
