← ScienceWhich consequence results when increased deuterium concentration degrades plasma confinement in a tokamak?
A)Neutron flux decreases dramatically
B)Bremsstrahlung radiation increases sharply✓
C)Alpha particle confinement enhances
D)Ion cyclotron heating stabilizes further
💡 Explanation
Increased deuterium causes enhanced Bremsstrahlung radiation via the increased fusion reaction rate, specifically *radiative losses*, because increased fuel density elevates the electron-ion collision frequency and radiative emissions; therefore Bremsstrahlung increases rather than neutron flux decreasing or other confinement improving in that condition.
