Final answer:
The premise of a nuclear power plant is to use fuel rods to generate heat while using control rods to prevent a meltdown.
Step-by-step explanation:
The premise of a nuclear power plant is to use fuel rods to generate heat while using control rods to prevent a meltdown. The fuel rods contain uranium pellets, which are a source of nuclear fuel. The control rods, made of neutron-absorbing material, regulate the chain reaction and control the release of heat.
