The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity.

What is an example of fission producing electricity?
Uranium and plutonium are most commonly used for fission reactions in nuclear power reactors because they are easy to initiate and control. The energy released by fission in these reactors heats water into steam. The steam is used to spin a turbine to produce carbon-free electricity.
How long has nuclear fission been used to generate electricity?
A major goal of nuclear research in the mid-1950s was to show that nuclear energy could produce electricity for commercial use. The first commercial electricity-generating plant powered by nuclear energy was located in Shippingport, Pennsylvania. It reached its full design power in 1957.
Is fusion or fission used to generate electricity?
Fission happens quite easily – and is used to generate electricity in conventional nuclear power stations. Fusion on the other hand, is the process of sticking together light nuclei (typically hydrogen -like nuclei). The larger nuclei again needs less energy to hold it together – so energy is released.
Why do we use nuclear fission and not fusion to generate electricity?
While fission is used in nuclear power reactors since it can be controlled, fusion is not yet utilized to produce power. Some scientists believe there are opportunities to do so. Fusion offers an appealing opportunity, since fusion creates less radioactive material than fission and has a nearly unlimited fuel supply.
How does fission generate energy?
In nuclear fission, atoms are split apart, which releases energy. All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation.
Is nuclear fusion safer than fission?
Fusion: inherently safe but challenging
Unlike nuclear fission, the nuclear fusion reaction in a tokamak is an inherently safe reaction. ... This is why fusion is still in the research and development phase – and fission is already making electricity.
Why is nuclear energy not used more?
The role of this virtually carbon-free power source has shrunk since its peak in 1996. Nuclear reactors supply steady, low-carbon energy—a valuable commodity in a world confronting climate change. Yet nuclear power's role has been diminishing for two decades. Bottom line: it's just too expensive.
When was nuclear energy first used for electricity?
Electricity was generated for the first time by a nuclear reactor on December 20, 1951, at the EBR-I experimental station near Arco, Idaho, which initially produced about 100 kW.
How much electricity does a nuclear power plant produce per year?
In 2020, the R.E. Ginna nuclear power plant actually generated a total of 4,332,888 MWh, achieving an annual average capacity factor of about 85%. Nuclear power reactors generally operate at or near their rated generating capacity throughout the year and have relatively high annual capacity factors.
What's the difference between nuclear fission and fusion?
The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one.
Are nuclear bombs fission or fusion?
Nuclear fission produces the atomic bomb, a weapon of mass destruction that uses power released by the splitting of atomic nuclei. When a single free neutron strikes the nucleus of an atom of radioactive material like uranium or plutonium, it knocks two or three more neutrons free.
Which produces more energy fission or fusion?
Elements heavier than Iron produce more energy through fission. Fission is when a large nucleus divides into smaller nuclei releasing energy. ... So, the answer is fusion produces more energy if it involves light elements and fission produces more energy if it involves heavy elements.
Does nuclear fission give off radiation?
Nuclear fission products are the atomic fragments left after a large atomic nucleus undergoes nuclear fission. ... Thus, fission events normally result in beta and gamma radiation, even though this radiation is not produced directly by the fission event itself.
What is nuclear fission used for?
Nuclear fission produces energy for nuclear power and drives the explosion of nuclear weapons. Both uses are possible because certain substances called nuclear fuels undergo fission when struck by fission neutrons, and in turn emit neutrons when they break apart.
How much more powerful is fusion than fission?
So it is easy to see that fusion reactions give out more energy per reaction. However, the energy per unit mass is more relevant. This is 0.7MeV for fission and 6.2MeV for fusion so it is obvious that fusion is the more effective nuclear reaction.
Does nuclear fusion release energy?
In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy. ... DT fusion produces a neutron and a helium nucleus.
Why did Chernobyl explode?
The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the environment, with the deposition of radioactive materials in many parts of Europe.
