← ScienceDuring uranium enrichment, which risk increases when centrifuge rotor speed hits resonance?
A)Kinetic energy rapidly converts destructive vibration✓
B)Isotope separation becomes energetically unfavorable
C)Enriched fuel spontaneously undergoes fission
D)Gamma emission induces material transmutation
💡 Explanation
Synchronous vibration causes the kinetic energy to amplify through mechanical resonance, thereby risking structural failure of components, because the excitation frequency matches a natural frequency of the rotor; therefore, answer A is correct, rather than isotope changes which need more energy.
