Nuclear energy can be used to create electricity, but it must first be released from the atom. ... As they split, the atoms release tiny particles called fission products. Fission products cause other uranium atoms to split, starting a chain reaction. The energy released from this chain reaction creates heat.

What must happen for a nuclear reactor to make electricity?
The water in the core is heated by nuclear fission and then pumped into tubes inside a heat exchanger. Those tubes heat a separate water source to create steam. The steam then turns an electric generator to produce electricity. The core water cycles back to the reactor to be reheated and the process is repeated.
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 is a nuclear fuel source used to generate electricity?
Nuclear power plants use heat produced during nuclear fission to heat water. ... 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.
How is nuclear energy used?
Nuclear energy can be used to create electricity, but it must first be released from the atom. ... A nuclear reactor, or power plant, is a series of machines that can control nuclear fission to produce electricity. The fuel that nuclear reactors use to produce nuclear fission is pellets of the element uranium.
What must happen for a nuclear reactor to make electricity apex?
They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity.
How is nuclear energy generated during nuclear fusion?
Nuclear Fusion reactions power the Sun and other stars. 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.
What are alternative methods to generate electricity using nuclear?
Some of these have been around for decades, are proven technology, and are much less harmful to the environment. The pursuit of these alternative types of energy such as thorium, solar power, natural gas, and hydrogen must continue despite the tragic accident in Japan.
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 has nuclear energy improved since it's invented?
Reactor concepts have evolved since then over the 60-year period of nuclear power reactor development, using other coolants such as gas, molten salt and liquid metals including sodium and lead that allow operation at higher temperatures and hence more efficient power cycles.
How has nuclear energy become safer?
Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels.
How much electricity can a nuclear power plant produce?
Nuclear energy has been powering the U.S. grid for the past 6 decades and produces around 1 gigawatt of power per plant on average.
Why should we use nuclear energy?
We should use nuclear power instead of other sources of energy because it can produce high levels of electricity without causing damage to our environment and atmosphere. ... Nuclear power plants produce less pollution than many of our other current energy sources, including coal fire and natural gas plants.
Why is nuclear energy not commonly used?
Barriers to and risks associated with an increasing use of nuclear energy include operational risks and the associated safety concerns, uranium mining risks, financial and regulatory risks, unresolved waste management issues, nuclear weapons proliferation concerns, and adverse public opinion.
How does nuclear energy impact the environment?
Nuclear energy produces radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
How is nuclear energy stored for later use?
The spent fuel is typically stored near the reactor in a deep pool of water called the spent fuel pool. During storage, the spent fuel cools down and begins to lose most of its radioactivity through radioactive decay.
