APFIVE Nuclear Reactor Fuel Depletion
A nuclear power plant uses uranium-235 (half-life 704 million years) as fuel. Why must the plant periodically replace its fuel rods despite the extremely long half-life?
A
The uranium-235 spontaneously transforms into fusion fuel
B
The half-life accelerates due to the chain reaction
C
Radiation damage to the fuel occurs independently of half-life
D
The concentration of fissile material decreases below critical levels
