← ScienceWhich increased risk results when magnetized plasma within a tokamak reactor undergoes disruptive instability?
A)Accelerated divertor plate erosion✓
B)Cryopump failure due to helium
C)Increased ohmic heating losses
D)Loss of neutron shielding efficacy
💡 Explanation
Disruptions cause rapid energy loss and plasma current spikes; therefore, sputtering from increased heat flux drastically increases on divertor plates via the Sputtering mechanism because particle energy bombards the divertor target plates, rather than uniform plasma confinement.
