When the multiplication factor is greater than 1, the power increases linearly.

Nuclear fission is a nuclear reaction that splits the nucleus of an atom into lighter nuclei. Nuclear reactors are machines that control nuclear chain reactions and release heat at a controlled rate.  Here are some types of nuclear reactors: Thermal-neutron reactors: Use slowed or thermal neutrons to keep up the fission of their fuel. Fast-neutron reactors: Use fast neutrons to cause fission in their fuel.  Nuclear reactors are used in nuclear power plants for electricity generation and in propulsion of ships.  Here's how a nuclear reactor works: A particle (a "neutron") is fired at an...

Nuclear fission is a nuclear reaction that splits the nucleus of an atom into lighter nuclei. Nuclear reactors are machines that control nuclear chain reactions and release heat at a controlled rate. 

Here are some types of nuclear reactors:
Thermal-neutron reactors: Use slowed or thermal neutrons to keep up the fission of their fuel.
Fast-neutron reactors: Use fast neutrons to cause fission in their fuel. 
Nuclear reactors are used in nuclear power plants for electricity generation and in propulsion of ships. 

Here's how a nuclear reactor works:
A particle (a "neutron") is fired at an atom.
The atom fissions into two smaller atoms and some additional neutrons.
The heat produced by the fission process is used to turn water into steam.
The steam drives turbine generators that generate electricity.
The unused steam is then condensed back to water and reused in the heating process. 

Nuclear reactors convert one third of heat produced into electricity. The remaining heat is released to the environment.
