Nuclear plants split atoms to heat water into steam. The steam turns a turbine to generate electricity.

Nuclear power

Nuclear Energy pp Cite as. The first nuclear reactors were built to produce Pu for bombs. Subsequently, reactors have been used for many other purposes, of which electricity generation is now, by far, the most prominent. Further uses have been to propel ships mostly naval vessels , to produce radioisotopes, and, to a limited extent, to supply heat. Many additional reactors have been built for teaching or research, much of the latter involving the study of the properties of materials under neutron bombardment and the intrinsic properties of neutrons and other subatomic particles.

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.

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. The principles for using nuclear power to produce electricity are the same for most types of reactor.

The heat energy in the nuclear power plant can be generated through a nuclear reaction or nuclear fission.

What is a Nuclear Power Plant : Working & Its Applications

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. These either drive a ship's propellers or turn electrical generators ' shafts.

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.


exploiting different sources of energy already operate which all follow the same principle based on the OPERATION OF A PWR-TYPE POWER PLANT.


A nuclear power plant is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity. Nuclear plants are usually considered to be base load stations since fuel is a small part of the cost of production [3] and because they cannot be easily or quickly dispatched.

    Nuclear reactor basic principles: 1. Neutron induced fission releases energy plus extra “fast” neutrons. 2. •Higher operating temperatures (greater thermal efficiency). •Secondary coolant , 32 of them are of CANDU type.`` www.​candu.

    Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant.
