Propagating Uncertainties from OpenMC MGXS into OpenMOC

[Hasan Ghotme]

Hello, dear developers. 

I’m wondering if there’s a way to estimate and carry over uncertainties from multi-group cross sections generated in OpenMC into OpenMOC calculations. 

Thank you!

Best regards,

Hello

It certainly is possible to do but there is nothing pre implemented that I know of.

If you end up implementing it, please feel free to contribute it back as an example. It should be possible to do strictly on the Python side.
