During deuterium-tritium fusion within a tokamak reactor, which effect increases as the plasma density limit is approached along the Greenwald Limit?

💡 Explanation

Energy confinement degrades because Bremsstrahlung radiation (electromagnetic radiation produced by the deceleration of a charged particle when deflected by another charged particle) drastically increases near the Greenwald limit. Therefore, radiative power loss becomes significant, rather than current stabilization or fuel increase as density varies.
