Nuclear energy is a form of large-scale, low-emission electricity generation. It accounts for a little over 10% of the world’s energy needs and produces about 25% of the world’s electricity. Nuclear power is also used in propulsion in ships and submarines, and in isotope production for medical diagnostics and treatments.
The nuclear reaction that occurs in a nuclear reactor is called nuclear fission, where heavy atoms such as uranium are split into lighter atoms such as lead or krypton, releasing large amounts of energy in the process.
Nuclear reactors come in many different sizes but they all work by using the heat from a reaction to turn water into steam which turns a turbine to make electricity.
The heat given off by this reaction has been used to warm.
Nuclear energy is a form of power that does not emit carbon dioxide and other greenhouse gases, but is often coupled with nuclear weapons proliferation risks.
The use of nuclear energy in the twentieth century has been linked to a number of cases of radioactive contamination.
In total, there have been about 150 confirmed cases of radioactive contamination from nuclear power plants.
Many more cases of contamination are suspected but not yet confirmed.
There has been constant debate and controversy over how to deal with the waste that nuclear plants produce. For example, what should we do with spent fuel rods? There are three general methods: storing them on-site indefinitely; storing them in interim storage facilities; dumping them at sea or in underground geological formations such as Yucca Mountain or Mount Callaghan. All these methods pose risks.
Nuclear power plants generate low-carbon electricity and produce no greenhouse gas emissions. The use of nuclear energy has been increasing after the oil crisis in 1973, because it is a reliable and economic type of power source.
Nuclear energy is a form of energy where the high-energy nuclei from a radioactive substance are used to heat water into steam that spins a turbine that then produces electricity. This type of energy is used in power plants to generate electricity for homes and businesses, and it is the largest source of non-carbon emitting electricity in many countries.
