Heating deposition for a specific nuclide and reaction

Dear all,

I would like to know the heating deposition for a specific nuclide of a specific reaction, in this case the heating deposition from the boron capture of neutrons in water, which release alpha particle 10 B(n, α ) 7Li. Here below, the tally that I use:

    tally_rrB=openmc.Tally(name="react. rates. B")
    cell_filt_cool=openmc.CellFilter([cCool])
    tally_rrB.filters.append(cell_filt_cool)
    tally_rrB.nuclides=['B10',]
    tally_rrB.scores=['heating', '(n,a)', 'absorption', '(n,gamma)']

In this case, the value of the heating generated in output, is the heating of all reactions (of neutrons, photon, electrons, positrons) with B10 ? If I use the particle filter with neutron selected, I would take only the heating of all neutron reactions (not only capture) with B10?

Thanks in advance for your time.
Best regards,

Christian

If you upload your tallies.xml I can help you better.

The neutron heating score will include all reactions. The nuclear data available does not separate out the different mechanisms of heating. But for B10, it’s going to be like 99% of the heating coming from the (n,a) reaction.
