← ScienceWhich risk increases when deuterium-tritium fuel purity decreases within a fusion reactor?
A)Reduced achievable plasma temperatures offset✓
B)Increased neutron flux towards components
C)Enhanced fuel confinement properties change
D)Elevated alpha particle energy deposition location
💡 Explanation
Inert contaminants dissipate energy by Bremsstrahlung radiation, hindering ignition because increased radiation causes radiative energy loss, preventing plasma temperature from reaching necessary fusion thresholds; therefore the reaction is suppressed rather than intensified by other means.
