How does nuclear fission produce energy?

A nuclear reactor produces and controls the release of energy from splitting the atoms of uranium. 

Uranium-fuelled nuclear power is a clean and efficient way of boiling water to make steam which drives turbine generators. Except for the reactor itself, a nuclear power station works like most coal or gas-fired power stations.

uh two lol

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
