← ScienceWhich risk during tokamak operation increases due to lower nuclear binding energy?
A)Plasma disruption events increase rapidly✓
B)Neutron activation of vessel walls falls
C)Fuel burn fraction achieves stability
D)Helium ash removal experiences stagnation
💡 Explanation
Reduced binding energy near the plasma edge enhances instability and lowers the threshold for disruptions arising from magneto-hydrodynamic effects. Because disruption outcomes become easier to initiate, therefore plasma disruptions are more frequent, increasing damage risk, rather than other consequences.
