← ScienceWhich mechanism initiates uncontrolled escalation in a fusion reactor?
A)Increased alpha particle thermalization✓
B)Decreased plasma ion confinement
C)Elevated divertor heat dissipation
D)Reduced fuel pellet injection frequency
💡 Explanation
Increased alpha particle thermalization causes runaway as the energy is transferred directly into the plasma as kinetic energy via ohmic heating, therefore overheating the system rather than dissipating leading to instability.
