How to get the jendl5-hdf5 crosssection library for multiple temperature?

Hello!
I am trying to use generate_jendl.py to create h5 file at different temperatures; But I found that there is only 294k in the. h5 file, and my question is how can I set the temperature I want?

Welcome to the community

Looking at the generate_jendl.py script and I see we don’t have any temperatures in there.

github.com

openmc-dev/data/blob/master/convert_jeff33.py

#!/usr/bin/env python

"""
Convert JEFF 3.3 ACE data distributed by OECD/NEA into an HDF5 library that can
be used by OpenMC. It will download archives containing all the ACE files,
extract them, convert them, and write HDF5 files into a destination directory.

import argparse
import tarfile
import sys
import os
from pathlib import Path
from shutil import rmtree
from urllib.parse import urljoin

import openmc.data

from utils import download

Here is an example of a processing script that does have temperatures https://github.com/openmc-dev/data/blob/master/convert_jeff32.py

I think the first step to getting temperature nuclear data files for JENDL but I had a quick look and didn’t see any here https://wwwndc.jaea.go.jp/jendl/j5/j5.html

Thanks Shimwell, very helpful.

Paul has kindly put in a PR to add temperatures to the JENDL script
