hey anas this is how you get the concentration of u235 with burnup time .
u can write this in the same file where you have your main program .

Thank you abdel, but i wanna plot core time operation (years) in x axis and burn up level (MWd/Kg) in y-axis. I don’t know how to do that. I hope you can help me :slight_smile:

You’ll have to do some small calculation.Burnup unit in OpenMC is ‘s’.you are also providing power density. After the depletion calculation u’ll be able to get time from result file. After that burnup is (MWd/KgHM)

B=( P*time/(seconds in a day))/(fuel weight)

After that u can simply plot B in X axis & time in Y axis.
Hope this helps.
