Errors/Standard Deviations in Depletion Calculations (Atom Number/Density)

Hi everyone,

I wanted to know if it is possible to obtain the standard deviations in the atom number of isotopes at each timestep during depletion calculations. I know the depletion module provides uncertainties in k_eff, but is it possible to get the same for atom densities or quantities of isotopes?

Recently, I received the first review for a paper I’m working on, which pertains to nuclide transmutation. The reviewer requested that I include the uncertainties in the transmutation amounts. For this, I need the uncertainties in the isotopic quantities of the relevant nuclides at each timestep.

Is there a mechanism in OpenMC (similar to SERPENT, where the output file lists uncertainties in all calculations) to obtain these uncertainties?

I would genuinely appreciate any help, especially from the developers. Thanks in advance!
