Nuclear power. Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants.
A nuclear power plant (NPP), [1] also known as a nuclear power station (NPS), nuclear generating station (NGS) or atomic power station (APS) 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 ...
The Chernobyl sarcophagus, built to contain the effects of the 1986 disaster. A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. When a fissile nucleus like uranium-235 or plutonium-239 absorbs ...
Nuclear fusion occurs when two atoms of a light element such as hydrogen are heated and fused together to form a heavier element such as helium. In order for that process to occur, the atoms must ...
The U.S. Army Nuclear Power Program formally commenced in 1954. Under its management, the 2 megawatt SM-1, at Fort Belvoir, Virginia, was the first in the United States to supply electricity in an industrial capacity to the commercial grid (VEPCO), in April 1957. [30]
Nuclear reactor physics. Pressurized water reactor: Projective representation of the thermal neutron flux of a fuel assembly of the 18×18 array with 300 fuel rods and 24 inserted control rods. Nuclear reactor physics is the field of physics that studies and deals with the applied study and engineering applications of chain reaction to induce a ...
The small modular reactor (SMR) is a class of small nuclear fission reactor, designed to be built in a factory, shipped to operational sites for installation and then used to power buildings or other commercial operations. The term SMR refers to the size, capacity and modular construction. Reactor type and the nuclear processes may vary.
Nuclear power can be described as all of the following: Nuclear technology (outline) – technology that involves the reactions of atomic nuclei. Among the notable nuclear technologies are nuclear power, nuclear medicine, and nuclear weapons. It has found applications from smoke detectors to nuclear reactors, and from gun sights to nuclear weapons.
