← ScienceWhich stability risk increases when inertial confinement of a deuterium-tritium pellet decreases inside a fusion reactor?
A)Increased alpha particle self-heating✓
B)Enhanced magnetic field interference
C)Reduced bremsstrahlung radiation losses
D)Augmented Lawson criterion achievement
💡 Explanation
Reduced inertial confinement allows greater mean free path for alpha particles; fusion-produced alpha particles escape pellet volume, therefore reducing alpha particle self-heating of the fuel, because less energy is redeposited, leading to a faster quenching of the fusion reaction, rather than alternatives that improve efficiency at reaction temperature.
