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. Heat from nuclear fission is passed to a working fluid water or gas , which in turn runs through steam turbines.

Nuclear power plant
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. The names can be a bit misleading: Both use steam to power a generator, but the difference is how they create it. Innovative entrepreneurs and startups are developing new types of reactors to be more efficient and flexible in operations, reach remote and developing areas, reduce—and possibly even recycle—waste, and even turn seawater into drinking water.
the plant and its components. To control these functions the nuclear power plant is divided into structural and functional entities, i.e. sys- tems. A system's safety.
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.

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 Power in a Clean Energy System
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.
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.
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.
A nuclear reactor or nuclear power plant consists of nuclear reactor fuel, control Most nuclear electricity is generated using just two kinds of reactor which were developed in the s and improved since. Components of a nuclear reactor In light water reactors the water moderator functions also as primary coolant.

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.
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.
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. It is shown that, without action, nuclear power in advanced economies could fall by two thirds by

In most naval reactors, steam drives a turbine directly for propulsion.
Какой-то тип разыскивал Меган. Человек не выпускал его из рук. - Да хватит тебе, Эдди! - Но, посмотрев в зеркало, он убедился, что это вовсе не его закадычный дружок. Лицо в шрамах и следах оспы.

Применив силу, говорил этот голос, ты столкнешься с сопротивлением. Но заставь противника думать так, как выгодно тебе, и у тебя вместо врага появится союзник.
