01 Definition
02 Detailed_Analysis
Low-neutron yield operation describes advanced fuel regimes (such as D-3He or p-11B) engineered to limit neutron power output to under 5% of total thermonuclear release. Achieved by tuning fuel ion ratios (e.g., 3He-rich mixtures) and maintaining high plasma operating temperatures, this regime minimizes activation of surrounding structural materials, avoids rapid material degradation, and eliminates heavy thermal cooling systems.
03 Key_Facts
- ▸ Restricts parasitic neutron energy output to <5% of total yield
- ▸ Reduces radiation damage and activation in reactor wall materials
- ▸ Enabled by helium-3 rich fuel balances or proton-boron-11 cycles
