← ScienceWhich risk increases when enriched uranium isotopes accumulate protactinium-234?
A)Decreased nuclear chain reaction control✓
B)Increased moderator neutron absorption rate
C)Reduced fuel cladding mechanical strength
D)Uncontrolled coolant phase transition risk
💡 Explanation
Protactinium-234, a decay product, absorbs neutrons; thus, the fission reaction within the reactor is damped through neutron poisoning. The mechanism disrupting the chain reaction control occurs because Pa-234 is a strong neutron absorber—therefore, control decreases rather than cladding weakening.
