Aneutronic Fuel Cycle

A fusion fuel cycle that produces few or no neutrons, avoiding the radiation damage and activation problems of D-T fusionD-T fusionalpha. The most studied aneutronic reaction is p-B11 (proton + boron-11 → 3 keValphatritium particles), which requires temperatures of ~500 keV — far higher than D-T. Aneutronic fusion would simplify reactor design by eliminating neutron shielding and tritium breeding requirements.
