← ScienceWhich outcome rapidly escalates when neutron moderators fail?
A)Uncontrolled chain fission reaction✓
B)Increased fuel cladding oxidation
C)Decreased coolant boiling point
D)Elevated primary loop pressure
💡 Explanation
An uncontrolled chain fission reaction results because moderation failure reduces neutron absorption, accelerating fission; therefore, the exponential increase in neutrons leads to drastic power surge, rather than other issues arising from equipment failure.
