Steam Generator (nuclear Power)
A steam generator (aka nuclear steam raising plant ('NSRP')) is a heat exchanger used to convert water into steam from heat produced in a nuclear reactor core. It is used in pressurized water reactors (PWRs), between the primary and secondary coolant loops. It is also used in liquid metal cooled reactors (LMRs), pressurized heavy-water reactors (PHWRs), and gas-cooled reactors (GCRs). In typical PWR designs, the primary coolant is high-purity water, kept under high pressure so it cannot boil. This primary coolant is pumped through the reactor core where it absorbs heat from the fuel rods. It then passes through the steam generator, where it transfers its heat (via conduction through metal) to lower-pressure water which is allowed to boil. Purpose Unlike PWRs, boiling water reactors (BWRs) do not use steam generators. The primary coolant is allowed to boil directly in the reactor core, and the steam is simply passed through a steam turbine. While theoretically simple, this has a ...

Pressurised Heavy Water Reactor
A pressurized heavy-water reactor (PHWR) is a nuclear reactor that uses heavy water (deuterium oxide D2O) as its coolant and neutron moderator. PHWRs frequently use natural uranium as fuel, but sometimes also use very low enriched uranium. The heavy water coolant is kept under pressure to avoid boiling, allowing it to reach higher temperature (mostly) without forming steam bubbles, exactly as for a pressurized water reactor (PWR). While heavy water is very expensive to isolate from ordinary water (often referred to as ''light water'' in contrast to ''heavy water''), its low absorption of neutrons greatly increases the neutron economy of the reactor, avoiding the need for enriched fuel. The high cost of the heavy water is offset by the lowered cost of using natural uranium and/or alternative fuel cycles. As of the beginning of 2001, 31 PHWRs were in operation, having a total capacity of 16.5 GW(e), representing roughly 7.76% by number and 4.7% by generating capacity of all curren ...

Combustion Engineering
Combustion Engineering (C-E) was a multi-national American-based engineering firm that developed nuclear steam supply power systems in the United States. Originally headquartered in New York City, C-E moved its corporate offices to Stamford, Connecticut, in 1973. C-E owned over three dozen other companies including Lummus Company, National Tank Company and the Morgan Door Company. The company was acquired by Asea Brown Boveri in early 1990. The boiler and fossil fuel businesses were purchased by Alstom in 2000, and the nuclear business was purchased by Westinghouse Electric Company also in 2000. History Founding Combustion Engineering was organized in 1912 through the merger of the Grieve Grate Company and the American Stoker Company, two well-known manufacturers of fuel burning equipment. The company was originally headquartered on Bowling Green Offices Building, 11 Broadway and at 43 ''-'' 5 ''-'' 7 Broad Street (Manhattan), both in Lower Manhattan. The city block was leased ...

Babcock & Wilcox
Babcock & Wilcox Enterprises, Inc. is an American energy technology and service provider that is active and has operations in many international markets with its headquarters in Akron, Ohio. Historically, the company is best known for their steam boilers. Background The company was founded in 1867 in Providence, Rhode Island, by partners Stephen Wilcox and George Herman Babcock, George Babcock to manufacture and market Wilcox's patented water-tube boiler. B&W's list of innovations and firsts include the world's first installed utility boiler (1881); manufacture of boilers to power New York City's first subway (1902); first pulverized coal power plant (1918); design and manufacture of components for , the world's first nuclear-powered submarine (1953–55); the first supercritical boiler, supercritical pressure coal-fired boiler (1957); design and supply of reactors for the first U.S. built nuclear-powered surface ship, (1961).''Steam/its generation and use'', 41st Edition Histo ...
