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.

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 is nuclear fission not possible?
Normally, fusion is not possible because the strongly repulsive electrostatic forces between the positively charged nuclei prevent them from getting close enough together to collide and for fusion to occur.
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.
How is electricity generated from a fission reaction?
The heat from the fission reaction heats the water and the water is pumped into a heat exchanger container where the heated water boils the water in the heat exchanger. The steam from there is forced through a turbine which spins a generator and produces electricity.
Do nuclear reactors use fission or fusion?
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.
Is nuclear fission better than nuclear fusion?
Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass).
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.
How is the energy produced by nuclear fission used?
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 sources use fission as a source of power?
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.
Why can't fusion produce electricity?
One of the biggest reasons why we haven't been able to harness power from fusion is that its energy requirements are unbelievably, terribly high. In order for fusion to occur, you need a temperature of at least 100,000,000 degrees Celsius. That's slightly more than 6 times the temperature of the Sun's core.
Is 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 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.
How can we use the nuclear fission of uranium 235 to produce electricity?
In a nuclear reactor the uranium fuel is assembled in such a way that a controlled fission chain reaction can be achieved. The heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity.
