How does nuclear fission produce energy? a controlled nuclear chain reaction produces heat, driving steam turbines to produce energy. moving water turns turbines to produce electricity. carbon atoms are bombarded by small neutrons. an uncontrolled nuclear reaction produces heat, driving steam turbines to 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.

The first option.

Option A

Explanation:

A controlled nuclear chain reaction produces heat, driving steam turbines to produce energy.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
