How do the nuclear reactions that power the Sun compare to the nuclear reactions that occur in a reactor at a nuclear power facility?

• Power plants release radiation and the sun does not

• Nuclear reactions on the sun are less powerful than nuclear reactions in power plants

• The Sun is powered via nuclear fusion while a nuclear power facility harnesses energy from nuclear fission

• Fission occurs on the sun while fusion occurs in a nuclear power facility
