Which risk increases when helium-3 concentration plateaus in DT fusion?

💡 Explanation

Thermal runaway risk increases because helium-3 accumulation reduces reactivity as DT fuel depletes. This mechanism results from neutron starvation because more efficient reactions fail to occur, therefore thermal energy concentrates, rather than neutrons increasing output efficiency.
