← ScienceWhich energy loss risk increases during tokamak operation?
A)Increased plasma radiation losses✓
B)Enhanced ohmic heating efficiency
C)Reduced alpha particle confinement
D)Decreased neutral beam effectiveness
💡 Explanation
Increased impurities cause bremsstrahlung via Coulomb collisions, triggering increased plasma radiation losses, because energy is radiated. Therefore, radiation losses rise, rather than ohmic heating improving under impurity influence or confinement being unaffected at a given impurity density.
