← ScienceWhich risk increases when a tokamak's magnetic field deviates?
A)Plasma current quench intensifies rapidly✓
B)Neutron flux exposure reduces
C)Tritium breeding ratio gets optimized
D)Helium ash confinement is sustainedlonger
💡 Explanation
Field deviations cause instabilities; therefore, the ITER plasma undergoes disruption via **magnetohydrodynamic instability** disrupting plasma equilibrium and causing a quench with severe thermal loads, rather than controlled fusion, because equilibrium is lost quickly.
