How does a nuclear reactor work? Nuclear reactors are, fundamentally, large kettles, which are used to heat water to produce enormous amounts of low-carbon electricity. They come in different sizes and shapes, and can be powered by a variety of different fuels. The Ringhals Nuclear Power Plant, home to four reactors capable of generating 20% of Sweden’s electricity demand (Image: Vattenfall) A nuclear reactor is driven by the splitting of atoms, a process called fission, where a particle (a ‘neutron’) is fired at an atom, which then fissions into two smaller atoms and some additional neutrons. Some of the neutrons that are released then hit other atoms, causing them to fission too and release more neutrons. This is called a chain reaction. The fissioning of atoms in the chain reaction also releases a large amount of energy as heat. The generated heat is removed from the reactor by a circulating fluid, typically water. This heat can then be used to generate steam, which drives turbines for electricity production. In order to ensure the nuclear reaction takes place at the right speed, reactors have systems that accelerate, slow or shut down the nuclear reaction, and the heat it produces. This is normally done with control rods, which typically are made out of neutron-absorbing materials such as silver and boron. Two examples of nuclear fissioning of uranium-235, the most commonly used fuel in nuclear reactors. Nuclear reactors come in many different shapes and sizes – some u...

Nuclear power plant (NPP) is a nuclear installation, the purpose of which is to generate electric power. Nuclear power and its device The principle of operation of a nuclear power plant Classification of nuclear power plants One-, two – and three-loop reactors of a nuclear power plant The advantages and disadvantages of nuclear power stations Nuclear power plant (NPP) is a nuclear installation, the purpose of which is to generate electric power. Nuclear power plant (NPP) is a nuclear installation for the production of electric energy in given modes and application conditions situated within a defined project territory, which for this purpose is used a nuclear reactor (reactors) and complex of necessary systems, devices, equipment and constructions with necessary employees (personnel). Unlike nuclear power plants from other types of power plants lies in the fact that its design includes a nuclear reactoras its main component. As fuel is uranium-235. NPP located on the territory of several buildings, which houses complex of buildings, systems and equipment required for its work. In the main building of the nuclear power plant is the reactor room, which houses: – reactor – special pool that is used to extract nuclear fuel, machine to perform the overload of fuel (handling machine). Operation of this equipment is controlled by the staff – operators, using for these purposes a control. A key element of the reactor zone, located in the concrete sump. It also provides for a syste...

India – nuclear power reactors work on the principle of nuclear power reactors work on the principle of– We are going to start the discussion about NUCLEAR POWER REACTORS WORK ON THE PRINCIPLE OF as per our readers’ demands and comments. If you want to know about this India topic, continue reading and learn more. People Also Read: Refer: nuclear reactor, any of a class of devices that can initiate and control a self-sustaining series of nuclear fissions. Nuclear reactors are used as research tools, as systems for producing radioactive isotopes, and most prominently as energy sources for nuclear power plants. A nuclear reactor is a device that is mainly used in nuclear power plants to control the nuclear chain reaction of radioactive elements. The prime application of nuclear reactors lies in the production of electricity. What is Nuclear Power Reactors | How does a nuclear reactor work? – World 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. Two examples of nuclear fissioning of uranium-235, the most commonly used fuel in nuclear reactors. Nuclear reactors come in many different shapes and sizes – some use water to cool their cores, whilst others use gas or liquid metal. Main Coponents of a Nuclear Reactor: ⦁ The Coe: It contains all the fuel and generates the heat required for energy production. ⦁ The Colnt: It passes throu...
