This repository contains part of the source code for neutron cross section plotting website xsplot.com which allows neutron cross sections for isotopes to be plotted.

This repository contains:

• A Python Plotly Dash based GUI 🐍
• A Dockerfile that provides the hosting environment 🐳

Run locally

You can view the hosted version of this repository here xsplot.com. However you might want to host your own version locally.

To host your own local version of xsplot.com you will need Docker installed and then can build and run the Dockerfile with the following commands.

First clone the repository

git clone https://github.com/openmc-data-storage/isotope-xs-plotter.git

Then navigate into the repository folder

cd isotope-xs-plotter

Then build the docker image

docker build -t isotope-xs-plotter .

Then run the docker image

docker run --network host -t isotope-xs-plotter

The URL of your locally hosted version should appear in the terminal, copy and paste this URL into a web browser address bar.

Maintenance

Pushing to the main branch of this repository triggers an automatic rebuild and deployment of the new code using Google Cloud build at the xsplot.com

The website makes use of a few other packages to process the nuclear data:

• openmc_data_downloader to download processed h5 nuclear data files.
• openmc_data_to_json to convert the h5 files (per isotope) into seperate reaction files.
• nuclear_data_base_docker to provide a dockerfile containing all the required nuclear data with an index / loop up file containing every reaction available.
