Which risk increases within a tokamak when fusion product confinement degrades?

A)Increased bremsstrahlung radiation heating
B)Reduced fuel confinement enhancement
C)Increased neutral beam backscattering
D)Reduced magnetohydrodynamic instability onset

💡 Explanation

Increased alpha particle losses deposit energy unevenly within the tokamak walls. This occurs because reduced Alpha particle thermalization leads to alpha particles striking plasma-facing components, rather than plasma core heating. Therefore, bremsstrahlung radiation increases, rather than net energy production.
