How does nuclear fission produce energy

Developing technology to harness nuclear fusion as a source of energy for heat and electricity generation is the subject of ongoing research, but whether or not it will be a commercially viable technology is not yet clear because of the difficulty in controlling a fusion reaction. Uranium is the fuel most widely used by nuclear plants for nuclear fission. Uranium is considered a nonrenewable energy source, even though it is a common metal found in rocks worldwide.

Nuclear power plants use a certain kind of uranium, referred to as U, for fuel because its atoms are easily split apart. Although uranium is about times more common than silver, U is relatively rare. Most U. Once uranium is mined, the U must be extracted and processed before it can be used as a fuel. Nuclear explained. What is energy? Units and calculators. Use of energy.

One downside to the use of fission as a method of generating electricity is the resulting daughter nuclei are radioactive. Below is a simulation showing how neutrons in a reactor result in fission events inside a fuel bundle.

On the simulation, a red flash inside the fuel rod means a fission event occurred, while a blue flash indicates neutron absorption. When nuclear fission is used to generate electricity, it is referred to as nuclear power. In this case, uranium is used as the nuclear fuel and its fission is triggered by the absorption of a slow moving thermal neutron.

Other isotopes that can be induced to fission like this are plutonium , uranium, and thorium However, currently there is not a method that allows us to access the power that fusion could produce.
