← ScienceWhich consequence results when helium accumulates in a fusion reactor core?
A)Bremsstrahlung radiation increases proportionally
B)Neutron flux uniformly decreases
C)Plasma confinement time diminishes✓
D)Tritium breeding reactions escalate
💡 Explanation
Helium buildup increases plasma instability and turbulence; therefore plasma confinement time diminishes because momentum and energy transport quicken via increased collisionality, rather than the flux uniformly varying because other factors maintain the overall balance.
