28 Σεπ 2024 · Nuclear energy, energy that is released in significant amounts in processes that affect atomic nuclei, the dense cores of atoms. One method of releasing nuclear energy is by controlled nuclear fission, used in nuclear power plants around the world.
Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy.
15 Νοε 2022 · Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together.
Nuclear energy and renewable technologies typically emit very little CO 2 per unit of energy production and are also much better than fossil fuels at limiting local air pollution. However, while some countries invest heavily in increasing their nuclear energy supply, others are shutting down their plants.
Nuclear energy is energy made by breaking the bonds that hold particles together inside an atom, a process called “nuclear fission.” This energy is “carbon-free,” meaning that like wind and solar , it does not directly produce carbon dioxide (CO 2 ) or other greenhouse gases that contribute to climate change.
When the electricity is made from atoms splitting apart, it's called nuclear energy. “Thermal” power plants convert heat into electricity using steam. At nuclear power plants, the heat to make the steam is created when atoms split apart — called fission. When atoms split apart, they release heat.
