Jeff3.3 Dataset in Jupyter Notebooks

User Support

Hello all,

I wanted to conduct simulations with various cells operating at different temperatures, however, I noticed that the default material data base only has information at 1 temperature for all nuclides. After some digging around the forum, I found and downloaded the Jeff 3.3 database. At this point, I am not sure how to apply the Jeff database to my current script in the Jupyter Notebook environment. Is it possible for someone to assist me on this?

Thanks in advance

Hi @alvinolay,

After expanding that downloaded data file (tar xvf nea_jeff33.tar.gz), you’ll want to set your OPENMC_CROSS_SECTIONS environment variable to point to the resulting directory. More details on cross section configuration can be found here in the documentation.

Best,

Patrick
