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.
Argonne National Laboratory was assigned by the United States Atomic Energy Commission (AEC) the lead role in developing commercial nuclear energy beginning in the 1940s. . Between then and the turn of the 21st century, Argonne designed, built, and operated fourteen reactors [21] at its site southwest of Chicago, and another fourteen reactors [21] at the National Reactors Testing Station in Idaho.
A fission nuclear power plant is generally composed of: a nuclear reactor, in which the nuclear reactions generating heat take place; a cooling system, which removes the heat from inside the reactor; a steam turbine, which transforms the heat into mechanical energy; an electric generator, which transforms the mechanical energy into electrical ...
The AP1000 design traces its history to two previous designs, the AP600 and the System 80.. The System 80 design was created by Combustion Engineering and featured a two-loop cooling system with a single steam generator paired with two reactor coolant pumps in each loop that makes it simpler and less expensive than systems which pair a single reactor coolant pump with a steam generator in each ...
A large reason Westinghouse entered development of the AP1000 was to improve the economies of scale that come with larger MWe plants. [1] The more powerful AP1000 was designed to have a similar footprint but a taller containment and a power output of 1000 MWe or greater.
A typical RPV. Russian Soviet era RBMK reactors have each fuel assembly enclosed in an individual 8 cm diameter pipe rather than having a pressure vessel. Whilst most power reactors do have a pressure vessel, they are generally classified by the type of coolant rather than by the configuration of the vessel used to contain the coolant.
SOFIA, Bulgaria (AP) — Bulgaria on Wednesday decided to expand the country’s nuclear power generation as an alternative to fossil fuels by launching the construction of two additional reactors ...
[5] Worker examines a pond for storing spent fuel rods at the Leningrad nuclear power plant in Sosnovy Bor. The maximum temperature of the spent fuel bundles decreases significantly between two and four years, and less from four to six years. The fuel pool water is continuously cooled to remove the heat produced by the spent fuel assemblies.
