Depletion Chains

User Support

Hi everyone,

I am running depletion calculations on a CANDU reactor (PHWR), and I was wondering if the simple depletion chain files that are pre-generated by OpenMC would be applicable to my simulation as it says they were created for PWR which is a LWR, and I am not familiar enough to know if there is a significant difference if any at all. From my understanding there shouldn’t be a difference, but since it was specified that they were meant for PWRs I was wondering if there was a reason. If there is a significant difference then I would need to generate them myself, but I don’t see where the input is that would differentiate it from a PHWR or LWR, though this might be due to my lack of understanding. Thanks for you assistance.

Dear Jarret, welcome to the openmc community.
You might want to look at the pre-generated depletion chain and its description from openmc. You can also compare each chain if you want.

Since PHWR still counts as a thermal reactor, I think it will be close enough to use a thermal chain.
