How is the heat generated by the reactor core of a nuclear power plant used to provide power to buildings?

• It is used directly to heat homes and offices
• It generates steam, which turns a turbine, powering a generator
• It generates steam, which is then condensed back to water. This process produces energy
• All of the above

Which of these statements correctly describes how the chain reaction occurs in nuclear fission?

• Uranium releases electrons to create electricity

• When a nuclear fission reaction occurs, enough energy is created to force other uranium nuclei to fuse together into one single nucleus.

• When a nuclear fission reaction occurs, emitted neutrons can strike other uranium nuclei, and cause them to split

• Protons and neutrons change to electrons because the nuclei are so big
