Hi,
I am trying to follow this notebook on OpenMC nuclear data, with the intent of modifying the nubar parameter for the isotope U-235 in the hdf5 ENDFB-VII.1 nuclear library:
https://docs.openmc.org/en/v0.12.2/examples/nuclear-data.html
however, the nubar MT=452 does not seem to be included in the U-235 reactions list. Where are these data stored and how should go about accessing them?
Many thanks,
Francesco
