Within a tokamak reactor, which risk strongly increases when impurity ions enter the plasma core during deuterium-tritium fusion?

💡 Explanation

Impurity ions in a tokamak enhance energy loss via Bremsstrahlung radiation, because the increased charge causes stronger electromagnetic emission; therefore plasma confinement time diminishes, rather than a quench which requires instability or adjustments to the magnetic field strength or significantly shifting neutron rates.
