How does a nuclear reactor produce energy?

• Atoms, such as uranium, undergo fusion in a reactor. This generates heat which turns water to steam in a turbine which generates electricity.

• Atoms, such as uranium, undergo fission in a reactor. This generates heat which turns water into steam in a turbine which generates electricity.

• Atoms, such as uranium, burn in a reactor. This generates heat which turns water to steam in a turbine which generates electricity.

• We do not currently have the technology to harness nuclear reactions to generate electricity.
