Question about the units of AverageFissionHeat postprocessor block

[gamma-spectrum]

Dear all,

I have Moltres (version 2025.09.02) within a MOOSE installation (version 2025.09.04) and I'm interested to reproduce the Molten Salt Reactor Experiment (MSRE) results.

I have focus on the model of GitHub repository 2017_annals_pub_msre_compare.

I have launched my compiled version of Moltres following the instructions of the web page

cd moltres/problems/2017_annals_pub_msre_compare
../../moltres-opt -i 2group.i

and I have obtained the Exodus output file 2group.e and also the CSV file with the postprocessor information (2group_out.csv).

Regarding the postprocessor information, I'm looking for information about AverageFissionHeat postprocessor block. I have accessed to its source webpage but it has few information. My question is in which units the result is given and if that postprocessor can be used to obtain the value for the moderator and the value for the whole reactor.

Kind regards,
Juan García
