Aneutronic Fuel Cycle

Glossary term: Aneutronic Fuel Cycle

CONCEPT Fusion Physics

01 Executive_Summary

A fusion fuel cycle that produces few or no neutrons, avoiding the radiation damage and activation problems of D-T fusion. The most studied aneutronic reaction is p-B11 (proton + boron-11 → 3 alpha 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.
