There are many kinds of nuclear fusion reactions

The lowest-threshold nuclear fusion reactions (deuterium–tritium (D–T) fusion, used by ITER, Commonwealth Fusion Systems) release up to 80% of their energy in the form of neutrons. These designs have to convert energy of the neutrons to electricity, indirectly using heat.
Since it is simpler to convert the energy of charged particles into electrical power than it is to convert energy from uncharged particles, an aneutronic reaction would be attractive for power systems. However, the conditions required to harness aneutronic fusion are much more extreme than those required for deuterium–tritium (D–T) fusion.
