Carolinas–Virginia Tube Reactor
Carolinas–Virginia Tube Reactor (CVTR), also known as Parr Nuclear Station, was an experimental pressurized tube heavy water nuclear power reactor at Parr, South Carolina in Fairfield County. It was built and operated by the Carolinas Virginia Nuclear Power Associates. CVTR was a small test reactor, capable of generating 17 megawatts of electricity. It was officially commissioned in December 1963 and left service in January 1967. Reactors using heavy water as their moderator have a number of advantages due to their improved neutron economy. This allows them to run on fuels that do not work in conventional light water reactors. CVTR, for instance, used slight enrichment, between 1.5 and 2%, compared to 3 to 5% for conventional designs. This means fuel costs are lower, the tradeoff being higher capital costs due to the need to buy heavy water. In conceptual terms, CVTR is very similar to the CANDU reactor design that was being pursued by Atomic Energy of Canada Limited aro ...

Fairfield County, South Carolina
Fairfield County is a county located in the U.S. state of South Carolina. As of the 2020 census, its population was 20,948. Its county seat is Winnsboro. Fairfield County is part of the Columbia, South Carolina metropolitan area. History 18th century It is alleged that the county name originated from a statement made by General Cornwallis when he declared "How Fair These Fields" during the British occupation of the area in 1780–81. The house Cornwallis stayed in during the occupation is still standing. Several years before the Revolution, Richard Winn from Virginia moved to what is now called Fairfield County. His lands covered the present site of Winnsboro, and as early as 1777 the settlement was known as "Winnsborough". The village was laid out and chartered in 1785 upon petition of Richard Winn, John Winn and John Vanderhorst. John Richard, and Minor Winn all served in the Revolutionary War. Richard was a General and he is said to have fought in more battles than any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiling Point
The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure. A liquid in a partial vacuum, i.e., under a lower pressure, has a lower boiling point than when that liquid is at atmospheric pressure. Because of this, water boils at 100°C (or with scientific precision: ) under standard pressure at sea level, but at at altitude. For a given pressure, different liquids will boiling, boil at different temperatures. The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, one Atmosphere (unit), atmosphere. At that temperature, the vapor pressure of the liquid becomes sufficient to overcome atmospheric pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone And Webster Engineering
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathering, transport, and deposition of existing rocks. M ...

Westinghouse Atomic Power Division
Westinghouse Electric Company LLC is an American nuclear power company formed in 1999 from the nuclear power division of the original Westinghouse Electric Corporation. It offers nuclear products and services to utilities internationally, including nuclear fuel, service and maintenance, instrumentation, control and design of nuclear power plants. Westinghouse's world headquarters are located in the Pittsburgh suburb of Cranberry Township, Pennsylvania. The company's main product is the AP1000, a modern pressurized water reactor (PWR) design with many passive safety features and modular construction intended to lower construction time and cost. Twelve AP1000 reactors are currently in operation with a further nineteen in various stages of planning. The company was initially formed as CBS Corporation spun off the remaining pieces of Westinghouse's industrial concerns, as part of Westinghouse's re-creation as a media company. Portions of their nuclear business were initially purchas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
