Crystal River Nuclear Plant
The Crystal River Nuclear Plant also called the Crystal River 3 Nuclear Power Plant, or simply CR-3, is a closed nuclear power plant located in Crystal River, Florida. The facility is currently being decommissioned and is transitioning to a SAFSTOR condition. The power plant was completed and licensed to operate in December 1976, and operated safely for 33 years until shutdown in September 2009. It was the third plant built as part of the Crystal River Energy Complex (CREC) which contains a single nuclear power plant, while sharing the site with four operational fossil fuel power plants. The Crystal River reactor went offline in September 2009 for refueling, OTSG replacement (once through steam generator), and 20% power up-rate outage. In preparing the containment building for making the opening to replace the two OTSG's, tendons in the containment building wall were detensioned. During the concrete removal in creating the opening workers discovered a large gap in the concrete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crystal River, Florida
Crystal River is a city in Citrus County, Florida, United States. The population was 3,108 in the 2010 census. According to the U.S. Census estimates of 2018, the city had a population of 3,162. The city was incorporated in 1903 and is the self professed "Home of the Manatee". Crystal River Preserve State Park is located nearby, and Crystal River Archaeological State Park is located in the city's northwest side. Crystal River is at the heart of the Nature Coast of Florida. The city is situated around Kings Bay, which is spring-fed so it keeps a constant temperature year round. A cluster of 50 springs designated as a first-magnitude system feeds Kings Bay. A first-magnitude system discharges 100 cubic feet or more of water per second, which equals about 64 million gallons of water per day. Because of this discharge amount, the Crystal River Springs group is the second largest springs group in Florida, the first being Wakulla Springs in Wakulla County near Tallahassee. Kings Bay ca ...

Nuclear Regulatory Commission
The Nuclear Regulatory Commission (NRC) is an independent agency of the United States government tasked with protecting public health and safety related to nuclear energy. Established by the Energy Reorganization Act of 1974, the NRC began operations on January 19, 1975, as one of two successor agencies to the United States Atomic Energy Commission. Its functions include overseeing reactor safety and security, administering reactor licensing and renewal, licensing radioactive materials, radionuclide safety, and managing the storage, security, recycling, and disposal of spent fuel. History Prior to 1975 the Atomic Energy Commission was in charge of matters regarding radionuclides. The AEC was dissolved, because it was perceived as unduly favoring the industry it was charged with regulating.John Byrne and Steven M. Hoffman (1996). ''Governing the Atom: The Politics of Risk'', Transaction Publishers, p. 163. The NRC was formed as an independent commission to oversee nuclear ene ...

Former Nuclear Power Stations In The United States
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Energy Infrastructure Completed In 1977
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Buildings And Structures In Citrus County, Florida
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towers In Florida
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...

Levy County Nuclear Power Plant
The Levy County Nuclear Power Plant was a proposed nuclear power plant in Levy County, Florida. Progress Energy Florida originally estimated that the reactors would cost $5 billion and would commence operation in 2016. It later became clear that the Levy County reactors would not have started operation until at least 2026. Since Progress filed its application for the new plant in 2008 demand for electricity had been growing very slowly, and natural gas prices were extremely low at the time. The utility estimated that the reactors would cost between $17 billion and $22 billion, not counting financing charges and cost overruns. According to economist Mark Cooper, opposition to the project has mounted, threatening a rerun of the 1970s and 1980s, when the majority of nuclear construction plans were canceled or abandoned. On August 1, 2013, Duke Energy terminated the engineering, procurement, and construction (EPC) agreement for the Levy nuclear project, as part of a settlement ...

2006 Gulf Of Mexico Earthquake
The 2006 Gulf of Mexico earthquake occurred in the eastern Gulf of Mexico on September 10 at . The intraplate earthquake measured 5.9 on the moment magnitude scale and its epicenter was located about west-southwest of Anna Maria, Florida. The event was felt throughout much of the Gulf Coast of the United States and was the second earthquake of magnitude 5 or greater in the Gulf during 2006. Felt intensities, as measured on the Mercalli intensity scale, were as high as IV (''Light'') in Florida, with parts of Georgia at III (''Weak''). Characteristics The quake was reportedly felt along the gulf coast and as far north as Georgia. The earthquake was the strongest in the Gulf of Mexico in 33 years and was an intraplate earthquake, an event that takes place away from the borders of tectonic plates (where most tectonic activity takes place). Earthquakes in the Southeastern United States are not common, but several strong events have occurred in the region. In 1879 close to St. Augustin ...

Radioactive Contamination
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition). Such contamination presents a hazard because the radioactive decay of the contaminants, produces ionizing radiation (namely alpha, beta, gamma rays and free neutrons). The degree of hazard is determined by the concentration of the contaminants, the energy of the radiation being emitted, the type of radiation, and the proximity of the contamination to organs of the body. It is important to be clear that the contamination gives rise to the radiation hazard, and the terms "radiation" and "contamination" are not interchangeable. The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge ...
