Nuclear reactors used to produce electricity are based on (a)nuclear fission (b)nuclear fusion (c)ColdFusion (d)superconductivity
option A. A nuclear reactor is a tool to provoke and manage a sustained nuclear chain reaction. Most usually they're used for producing power and for the propulsion of ships. Usually warmth from nuclear fission is surpassed to a running fluid (water or gas), which runs thru mills that energy both ship's propellers or generators.
