Nuclear energy is a source of energy that is based on the process of nuclear fission inside a nuclear reactor. This process releases huge amounts of heat energy which is then converted into electricity. There has always been a debate about the use of nuclear energy as an alternative energy source to fossil fuels.
On the one hand, nuclear energy is considered a clean energy source as it does not produce greenhouse gas emissions or other atmospheric pollutants. Additionally, nuclear reactors are capable of producing electricity 24/7, making them highly reliable as an energy source.
On the other hand, there are concerns about the safety of nuclear power plants, both in terms of the possibility of nuclear accidents and the long-term management of radioactive waste that remains for many hundreds of years. There is also the issue of nuclear proliferation, or the concern that access to nuclear technology may be used for military purposes.
Nuclear energy is often criticized for its high initial construction and decommissioning costs, and the several years needed from the start of construction to full operation.
