Burn up

[shimwell]

OpenMC is implementing a burn up feature for fixed source simulations.

openmc-dev/openmc#1628

Once this is merged in we should make an example that shows tbr as a function of time. Li6 burn up should mean tbr decreases as a function of time in regular blankets. Perhaps a layered solid blanket would be the best to highlight this effect

The burn up feature has now been merged into openmc development branch

to make this example there are some useful resources

The pin cell depletion example shows how to do burn up for fission sources

The example made for the workshop should do two things

1. show the number of Li6 and L7 atoms as a function of time

2. show the TBR as a function of time

[shimwell]

Andy D made a nice example that can obtain the number of atoms, thanks Andy

Ah that last line in the above screen shot should be results.get_atoms("1", "Co60")
