Question

to generate power, uranium atoms in fuel rods
a are hit by tiny particles so that they split apart
b are safe as long as the uranium stays in the rods
c fuses into lead, which releases energy
d all of the above

Explanation:

In nuclear power generation, uranium atoms in fuel rods undergo fission. They are hit by neutrons (tiny particles) causing them to split apart. Uranium in fuel - rods is relatively safe as long as it remains contained. Uranium does not fuse into lead in a nuclear power - plant process; it undergoes fission.

Answer:

A. Are hit by tiny particles so that they split apart
