It was the first commercial Advanced Gas Cooled reactor to generate power to the National Grid in 1976 and shares its design with sister station Hunterston B nuclear power station. Hunterston B nuclear power station is a nuclear power station in North Ayrshire, Scotland. The preliminary concept of the carbon dioxide cooled fast reactor EGCR has been studied as a Generation IV system. Note that the heat exchanger is contained within the steel-reinforced concrete combined pressure vessel and radiation shield. The Steam Generating Heavy Water Reactor (SGHWR) is a United Kingdom design for commercial nuclear reactors. [10] The following reactor designs at Hinkley Point and Hunterston significantly improved on the original design and indeed were commissioned ahead of Dungeness. Gas. The UK’s fleet of AGRs totals 14 units at 6 sites. Reactor Avanzado Enfriado por Gas (AGR) Estos son los reactores Británicos de Segunda Generación enfriados a gas, que usan un moderador de grafito y dióxido de carbono como refrigerante. These either drive a ship's propellers or turn electrical generators' shafts. EGCR with MOX fuel has a very good core performance, a breeding ratio over 1.2, a long operating cycle of 24 months, and a high burnup of 150GWd/t. Graphite moderator 4. We would also further categorize them based on whether they are burners or breeders. Only refuelling at part load or when shut down is now undertaken at AGRs. It was also claimed that British Energy did not know why the cracking had occurred and that they were unable to monitor the cores without first shutting down the reactors. All of these are configured with two reactors in a single building, and each reactor has a design thermal power output of 1,500 MWt driving a 660 MWe turbine-alternator set. The name refers to its unusual design where, instead of a large steel pressure vessel surrounding the entire core, each fuel assembly is enclosed in an individual 8 cm diameter pipe which allows the flow of cooling water around the fuel. EDF Energy is a British integrated energy company with operations spanning electricity generation and the sale of natural gas and electricity to homes and businesses throughout the United Kingdom. A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self-sustained nuclear chain reaction. These life extensions are subject to detailed review and approval, and are not included in the table above. The lower two diagrams show the load force applied on brushes. nuclear reactor demonstrating the feasibility of a sustained and controlled chain reaction was built in Chicago in 1942.In 1957, a nuclear reactor produced electricity for the first time.For the past 50 years, significant technological progress has been achieved. The following pages on the English Wikipedia use this file (pages on other projects are not listed): (SVG file, nominally 1,071 × 786 pixels, file size: 87 KB). These were made identical to those of a coal fired plant, allowing the same design of turbines and generation equipment to be used. A total of fourteen AGR reactors at six sites were built between 1976 and 1988. This project was also a study of what is required to decommission a nuclear reactor safely. action between the wall of the fuel channel and the fuel assembly supporting brushes. 650oC .

Scottish Nuclear was formed as a precursor to the privatization of the electricity supply industry in Scotland on 1 April 1990.
