Which critical fuel constraint arises because density plateaus prevent sustained fusion in a Tokamak reactor?

💡 Explanation

Bremsstrahlung radiation dominates alpha heating causing plasma cooling; because the density limit curtails further fuel input, power breakeven is unattainable. Therefore, reactor efficiency plummets, rather than attaining higher stability by other hypothetical plasma behaviors.
