"They say the combined reaction will produce only 6% of its energy as neutron radiation, compared to 80% for D-T."
Neutrons are a design requirement for typical tritium breeding fusion reactors, but highly undesirable for Helion's D-He3 D-D reactor. I'd expect a 100x neutron flux reduction at activating energies over typical D-T.
