With a sodium material at ~ 977K, the model I’m running is throwing the following error:
RuntimeError: Nuclear data library does not contain cross sections for Na23 at or near 977.59440 K.
According to this post (Using high temperature cross-sections in OpenMC - #5 by Julien), this error can come from using HDF5 data that was produced using an older version of OpenMC than the running version. As far as I know, I’m using the latest version of both OpenMC and the nuclear data (see below), so I’m not sure what the issue is. Thoughts?
OpenMC version: 0.13.0-dev
Nuclear data: https://openmc.org/official-data-libraries/ (ENDF/B-VII.1)
I will also try running with the other available libraries.
