Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a gearbox or through an electric generator and motor. Nuclear propulsion is used primarily within naval warships such as nuclear submarines and supercarriers. A small number of experimental civil nuclear ships have been built.

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.
Aqueous homogeneous reactors (AHR) are a type of nuclear reactor in which soluble nuclear salts are dissolved in water. The fuel is mixed with the coolant and the moderator, thus the name "homogeneous". The water can be either heavy water or ordinary (light) water, both of which need to be very pure.
A Steam generator is a heat exchanger used to convert water into steam from heat produced in a nuclear reactor core. They are used in pressurized water reactors (PWR) between the primary and secondary coolant loops.
Doosan Enerbility Co., Ltd., formerly known as Doosan Heavy Industries, is a heavy industrial company headquartered in Changwon, South Korea. It was established in 1962. Its business includes manufacturing and construction of nuclear power plants, thermal power stations, turbines and generators, desalination plants, castings, and forgings.
Heysham nuclear power station is operated by EDF Energy in Heysham, Lancashire, England. The site is divided into two separately-managed nuclear power stations, Heysham 1 and Heysham 2, both with two reactors of the advanced gas-cooled reactor (AGR) type.
Babcock International Group plc is a British aerospace, defence and nuclear engineering services company based in London, England. It specialises in managing complex assets and infrastructure. Although the company has civil contracts, its main business is with public bodies, particularly the United Kingdom's Ministry of Defence and Network Rail.

The Sizewell nuclear site consists of two nuclear power stations, one of which is still operational, located near the small fishing village of Sizewell in Suffolk, England. Sizewell A, with two Magnox reactors, is now in the process of being decommissioned. Sizewell B has a single pressurised water reactor (PWR) and is the UK's newest nuclear power station. A third power station, to consist of twin EPR reactors, is planned to be built as Sizewell C.
Cockle Creek Power Station was located in Teralba, New South Wales, Australia on the banks of Cockle Creek. The power stationed operated from 11 March 1927 until March 1976.
Altrad Babcock Ltd is part of Altrad.
The B&W mPower was a proposed small modular reactor designed by Babcock & Wilcox, and to be built by Generation mPower LLC, a joint venture of Babcock & Wilcox and Bechtel. It was a Generation III+ integral pressurized water reactor concept.
NuScale Power Corporation is a publicly traded American company that designs and markets small modular reactors (SMRs). It is headquartered in Portland, Oregon. A 50 MWe version of the design was certified by the US Nuclear Regulatory Commission (NRC) in January 2023. NuScale has agreements to build reactors in Idaho in 2029 and 2030.
Hayle Power Station was a coal-fired power station situated at the mouth of the River Hayle, at Hayle in Cornwall, South West England.
Deutsche Babcock AG was a German manufacturing company based in Oberhausen in the Ruhr District, the center of the German economy. The company was established in 1898 as a German subsidiary of the British boilermaking company Babcock & Wilcox, Limited. In the beginning of the 20th century and the interwar period Deutsche Babcock expanded its business across the German Empire and the countries of Eastern Europe and, to a lesser extent, Scandinavian countries. Financial success and military conflicts between Germany and the United Kingdom led to de facto independence of Deutsche Babcock from its British parent, although the British owned the controlling interest in Deutsche Babcock until 1975.
GE Hitachi Nuclear Energy (GEH) is a provider of advanced reactors and nuclear services. It is headquartered in Wilmington, North Carolina, United States. Established in June 2007, GEH is a nuclear alliance created by General Electric and Hitachi. In Japan, the alliance is Hitachi-GE Nuclear Energy. In November 2015, Jay Wileman was appointed CEO.
Steam-powered vessels include steamboats and steamships. Smaller steamboats were developed first. They were replaced by larger steamships which were often ocean-going. Steamships required a change in propulsion technology from sail to paddlewheel to screw to steam turbines. The latter innovation changed the design of vessels to one that could move faster through the water. Engine propulsion changed to steam turbine in the early 20th century. In the latter part of the 20th century, these, in turn, were replaced by gas turbines.
The Goldie & McCulloch Company Ltd. was a Canadian steam engine manufacturer based in Galt, Ontario. The company also manufactured woodworking machinery, industrial safes, French Burr millstones, boilers, turbine water wheels, bark mills and a variety of tannery machines. They primarily supplied the Canadian market, but the company had a strong export business to Mexico and South America.
