OpenMC currently handles photoatomic interactions and atomic relaxation but isn't capable of handling photonuclear reactions. To be clear, there are no current plans to implement this that I am aware...
After #1171 is merged, we no longer have any Fortran code in OpenMC. However, there are still some things that need cleaning up on the C++ side. I wanted to...
One of OpenMC's "bad" behaviors right now is that when it encounters an error, it most circumstances it will call `std::exit` (or `MPI_Abort` when using MPI). This is not a...
I met with similar issue as well. Take an example for B-10 (n, alpha) reaction rate at BOC of VERA 2E testing case,  This will cause significantly increased B-11...
Right now heating tallies rely on tabulated data in the MT=301 or MT=901 cross sections. When multipole is turned on, a check for the temperature index (which is -1 when...
A [user](https://openmc.discourse.group/t/iterations-of-volumecalculation/826/3) made two good suggestions regarding volume calculations: 1. Add a `max_iteration` attribute for the user to set that prevents volume calculations from running forever if the trigger threshold...
A user [reported](https://openmc.discourse.group/t/segmentation-fault-in-volume-calculation/816) a segfault when trying to run a volume calculation with multigroup cross sections in their materials. The problem it runs into is that it tries to access...
Right now, we have an option for determining fission product yields (FPYs) by tallying the average energy causing fission and then linearly interpolating between tabulated yields. Right now, this is...
Although our depletion chain files do list spontaneous fission as a decay mode, we don't utilize ENDF spontaneous fission product yield sublibrary files, so no fission products are produced from...
Our `search_for_keff` Python function currently uses optimization functions from SciPy that do not take into account the uncertainty in keff estimates. A few papers in the literature have proposed methods...
