A nuclear reactor , formerly known as an atomic pile , is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion.

Nuclear power and hydropower form the backbone of low-carbon electricity generation. Together, they provide three-quarters of global low-carbon generation. However, in advanced economies, nuclear power has begun to fade, with plants closing and little new investment made, just when the world requires more low-carbon electricity. This report focuses on the role of nuclear power in advanced economies and the factors that put nuclear power at risk of future decline.

Nuclear reactor , any of a class of devices that can initiate and control a self-sustaining series of nuclear fission s. Nuclear reactors are used as research tools, as systems for producing radioactive isotope s, and most prominently as energy sources for nuclear power plants. Nuclear reactors operate on the principle of nuclear fission, the process in which a heavy atomic nucleus splits into two smaller fragments. The nuclear fragments are in very excited states and emit neutron s, other subatomic particle s, and photon s. The emitted neutrons may then cause new fissions, which in turn yield more neutrons, and so forth. Such a continuous self-sustaining series of fissions constitutes a fission chain reaction.

Published Jul 27, Updated Jan 29, Atoms are constructed like miniature solar systems. At the center of the atom is the nucleus; orbiting around it are electrons. The nucleus is composed of protons and neutrons, very densely packed together. Hydrogen, the lightest element, has one proton; the heaviest natural element, uranium, has 92 protons. The nucleus of an atom is held together with great force, the "strongest force in nature. Because uranium atoms are so large, the atomic force that binds it together is relatively weak, making uranium good for fission.

Basic Layout and Working of a Nuclear Power Plant

This page is about the main conventional types of nuclear reactor. A nuclear reactor produces and controls the release of energy from splitting the atoms of certain elements. In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity.

This page is about the main conventional types of nuclear reactor. A nuclear reactor produces and controls the release of energy from splitting the atoms of certain elements. In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity. In a research reactor the main purpose is to utilise the actual neutrons produced in the core. In most naval reactors, steam drives a turbine directly for propulsion.

In a nuclear power plant , heat energy is generated by a nuclear reaction called as nuclear fission. Nuclear fission of heavy elements such as Uranium or Thorium is carried out in a special apparatus called as a nuclear reactor.

Nuclear reactor

Nuclear power plants are a type of power plant that use the process of nuclear fission in order to generate electricity. They do this by using nuclear reactors in combination with the Rankine cycle , where the heat generated by the reactor converts water into steam , which spins a turbine and a generator. Aside from the source of heat , nuclear power plants are very similar to coal-fired power plants. However, they require different safety measures since the use of nuclear fuel has vastly different properties from coal or other fossil fuels. They get their thermal power from splitting the nuclei of atoms in their reactor core, with uranium being the dominant choice of fuel in the world today. Thorium also has potential use in nuclear power production, however it is not currently in use. Below is the basic operation of a boiling water power plant , which shows the many components of a power plant, along with the generation of electricity.

Nuclear power plants produce electricity from the heat created when atoms are split within a nuclear reactor. This process is called fission. Uranium is the fuel most widely used in nuclear reactors at power plants. Nuclear energy is created when uranium atoms are split in a process called fission. Fission releases a tremendous amount of energy in the form of heat. This heat creates steam that is used to turn a steam turbine. The turbine is connected to an electric generator, which generates electricity.

Nuclear plants split atoms to heat water into steam. The steam turns a turbine to generate electricity. In most power plants, you need to spin a turbine to generate electricity. Coal, natural gas, oil and nuclear energy use their fuel to turn water into steam and use that steam to turn the turbine. The nuclear reactors currently operating in the United States are either boiling water reactors or pressurized water reactors.
