Chain.xml file for gfr

Hello everyone,

I want to do a depletion calculation, I’m doing a project designing a GFR. in openmc, there is a chain_casl_sfr.xml file for depletion. Can I also use that file to perform depletion calculations on my project or is there a chain.xml file for the GFR itself? Can anyone tell me what to do

chain = openmc.deplete.Chain.from_xml("./chain_casl_sfr.xml")

Thanks
Aldi

I would recommend using the SFR depletion chain (the one you listed above) since it is already intended for a fast spectrum. The only thing in the chain files that depends on the neutron spectrum are some of the capture branching ratios, and they should be very close for a GFR relative to an SFR.

Okay Paul, I get it. Thanks for your recommendation.
