Chain file management / depletion execution

I am sequential depletion operations on a materials file, with a “purification” step after each run which consists of stripping all the noble gases - which gets rid of the xenon isotopes. Is there a way to keep the chain file resident in memory to reduce the amount of time taken to reload the chain file data?

Alternatively, I have worked through how to restart a depletion - can do that successfully. Is there a way to “fudge” the last material result in the depletion results file?

Thanks. Brian

@Brian729 you might be interested in the pull request into OpenMC

I’m sure any feedback would be appreciated on the pull request as it is currently open and being reviewed.

Thanks for this input. I am not very familiar with github - if I do a build with the default source do I get this added capability? (Guess I can test to find out)

you would have to checkout that branch and build from that branch

the commands would be something like this.

But be careful with these as I don’t want to mess up your current python / openmc environment. Perhaps best in a different python environment

git clone https://github.com/openmsr/openmc.git
cd openmc
git checkout msr_13.2_cont
mkdir build
cd build
cmake ..
make -j
make -j install
cd ..
pip install .
