Question

The source of energy in nuclear power reactor is :
A Nuclear fission reaction
B Exothermic chemical reaction
Nuclear fusion reaction
D
Controlled nuclear fission chain reaction​

Answer 1

Answer:

The fuel that nuclear reactors use to produce nuclear fission is pellets of the element uranium. ... Fission products cause other uranium atoms to split, starting a chain reaction. The energy released from this chain reaction creates heat. The heat created by nuclear fission warms the reactor's cooling agent.
