Floating Nuclear Power Plant
A floating nuclear power plant is a floating power station that derives its energy from a nuclear reactor. Instead of a stationary complex on land, they consist of a floating structure such as an offshore platform, barge or conventional ship. Since the reactors employed are smaller in size and power than most commercial land-based reactors, mostly derived from nuclear ship and submarine power plants, the power output is generally a fraction of a conventional nuclear power plant, usually around 100MWe, although some are planned to have as much as 800MWe. The advantage of such power plants is their relative mobility and their ability to deliver in-situ electric power "on demand" even to remote regions, since they can be moved or towed to position with relative ease within large water bodies, and then docked with coastal facilities to transfer the produced power and heat to a land power grid. History 20th century The first floating nuclear power station was the MH-1A, using p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nuclear Power Plant
A nuclear power plant (NPP) 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 electric generator, generator that produces electricity. , the International Atomic Energy Agency reported there were 422 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction. Nuclear plants are very often used for base load since their operations, maintenance, and fuel costs are at the lower end of the spectrum of costs. However, building a nuclear power plant often spans five to ten years, which can accrue to significant financial costs, depending on how the initial investments are financed. Nuclear power plants have a carbon footprint comparable to that of renewable energy such as photovoltaic power station, solar farms and wind farms, and much lower than fossil fuels such as gas-fired ...

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. Nuclear ''decay'' processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as ''Voyager 2''. Generating electricity from fusion power, ''fusion'' power remains the focus of international research. Most nuclear power plants use thermal reactors with enriched uranium in a Nuclear fuel cycle#Once-through nuclear fuel cycle, once-through fuel cycle. Fuel is removed when the percentage of neutron poison, neutron absorbing atoms becomes so large that a nuclear chain reaction, chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools before being tr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Molten Salt Reactor
A molten salt reactor (MSR) is a class of nuclear fission reactor in which the primary nuclear reactor coolant and/or the fuel is a molten salt mixture. Only two MSRs have ever operated, both research reactors in the United States. The 1950's Aircraft Reactor Experiment was primarily motivated by the compact size that the technique offers, while the 1960's Molten-Salt Reactor Experiment aimed to prove the concept of a nuclear power plant which implements a thorium fuel cycle in a breeder reactor. Increased research into Generation IV reactor designs began to renew interest in the technology, with multiple nations having projects, and , China is on the verge of starting its TMSR-LF1 thorium MSR. MSRs are considered safer than conventional reactors because they operate with fuel already in a molten state, and in some designs in the event of an emergency, the fuel mixture is designed to drain from the core to a containment vessel where it will solidify in fuel drain tanks.

NuScale Power
NuScale Power is a publicly traded American company that designs and markets small modular reactors (SMRs). It is headquartered in Tigard, Oregon, United States. NuScale has been approved to build reactors in Idaho, in 2029 and 2030. The design was approved for certification in July 2022. NuScale's SMR designs are for diameter by high reactor vessels that use conventional light water cooling methods and run on low enriched uranium fuel assemblies based on existing light water reactor designs. Each module is intended to be kept in an underground pool and is expected to produce about 60 megawatts of electricity. Its coolant loop uses natural water-circulation, fed from a large water reservoir, that can operate without powered pumps. NuScale was founded based on research funded by the United States Department of Energy from 2000 to 2003. After funding was cut, scientists with the program obtained related patents in 2007 and started NuScale to commercialize the technology. Cor ...

Offshore Power Systems
Offshore Power Systems (OPS) was a 1970 joint venture between Westinghouse Electric Company, which constructed nuclear generating plants, and Newport News Shipbuilding and Drydock, which had recently merged with Tenneco, to create floating nuclear power plants at Jacksonville, Florida.Adams, Rod"Offshore Power Systems: Big Plants for a Big Customer"Atomic Insights, August 1996Putnam, Walter"Floating nuclear plants may become reality"Boca Raton News, November 15, 1981 History The MH-1A was the first floating nuclear power station, built by Martin Marietta for the US Army in the early 1960s. The reactor was installed in a converted Liberty ship hull and used by the Army from 1968 to 1975 in the Panama Canal Zone. It produced relatively low power output of 10 megawatts compared to the projected 2,300 megawatt capacity of the OPS plants. The much larger concept was envisioned in 1969 by Richard Eckert, the engineer at Public Service Electric and Gas Company (PSE&G) tasked with id ...

Liberty Ship
Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. Their production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types during World War I. The immensity of the effort, the number of ships built, the role of female workers in their construction, and the survival of some far longer than their original five-year design life combine to make them th ...

Floating Power Station
A powership (or power ship) is a special purpose ship, on which a power plant is installed to serve as a power generation resource. Converted from existing ships, powerships are self-propelled, ready to go infrastructure for developing countries that plug into national grids where required. Unmotorised powerships, known as power barges, are power plants installed on a deck barge. These are sometimes called "floating power plants" or "barge mounted power plants". They were initially developed during World War II by General Electric for the War Production Board as a transportable large-scale power generation resource. Powerships or power barges can be equipped with single or multiple gas turbines, reciprocating diesel and gas engines, boilers or nuclear reactors for electricity generation. Bureau Veritas, an international certification agency with experience in overseeing both shipbuilding and power plant development, classifies such floating power plants as "special service power ...
