“…For resource utilization and sustainability goals, it is useful to compare the overall neutron "balance" of the transmutation process; a physics approach was developed in Ref. 4. The basic approach is to track the neutron balance for transmutation from the source isotope to extinction; fission and (n,2n) reactions produce neutrons while capture reactions consume neutrons.…”
