For what is the heat of a nuclear reactor core used?

A) To begin the fusion reaction
B) To convert to DC energy
C) To begin the fission reaction
D) To convert water to steam

Nuclear Reactor Core

The central part of a nuclear reactor where nuclear fission occurs, producing heat to generate electricity in nuclear power plants.

Fusion Reaction

A nuclear reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles, releasing large amounts of energy.

Fission Reaction

A nuclear reaction in which a heavy nucleus splits into smaller nuclei, releasing energy and, often, neutrons.
