Dounreay
Dounreay (; gd, Dùnrath) is a small settlement and the site of two large nuclear establishments on the north coast of Caithness in the Highland area of Scotland. It is on the A836 road west of Thurso. The nuclear establishments were created in the 1950s. They were the Nuclear Power Development Establishment (NPDE) for the development of civil fast breeder reactors, and the Vulcan Naval Reactor Test Establishment (NRTE), a military submarine reactor testing facility. Both these no longer perform their original research functions and will be completely decommissioned, some of which has been in progress for a while. The two establishments have been a major element in the economy of Thurso and Caithness, but this will decrease with the progress of decommissioning. The NPDE will enter an interim care and surveillance state by 2036, and become a brownfield site by 2336.

Thurso
Thurso (pronounced ; sco, Thursa, gd, Inbhir Theòrsa ) is a town and former burgh on the north coast of the Highland council area of Scotland. Situated in the historical County of Caithness, it is the northernmost town on the island of Great Britain. From a latitudal standpoint, Thurso is located further north than the southernmost point of Norway and in addition lies more than north of London. It lies at the junction of the north–south A9 road and the west–east A836 road, connected to Bridge of Forss in the west and Castletown in the east. The River Thurso flows through the town and into Thurso Bay and the Pentland Firth. The river estuary serves as a small harbour. At the 2011 Census, Thurso had a population of 7,933. The larger Thurso civil parish including the town and the surrounding countryside had a population of 9,112. Thurso functioned as an important Norse port, and later traded with ports throughout northern Europe until the 19th century. A thriving fish ...

RAF Dounreay
RAF Dounreay was built for RAF Coastal Command in 1944, but not used by them. It was transferred to the Royal Navy as HMS Tern II, but not commissioned and on care and maintenance until 1954. In 1955 the airfield was taken over by the United Kingdom Atomic Energy Authority (UKAEA) for developing a fast breeder reactor. One runway was kept operational until the 1990s for transport to/from the site.

Sandside Chase
The Sandside Chase (The Chase of Sandside, The Chase of Sansett; in Gaelic, Ruoig-Hansett, Ruaig Handside or Ruaig-Shansaid) was a Scottish clan battle which took place in 1437 in Caithness, about west of Thurso. The Clan Mackay launched a raid from Strathnaver towards Thurso until they encountered resistance from the locals at Dounreay. The Mackays then pulled back to Sandside, where they were joined by reinforcements and slaughtered the defenders on the coast north of Reay. Background Neil Mackay, 8th of Strathnaver, son of Angus Du Mackay, 7th of Strathnaver, chief of Clan Mackay had been imprisoned on the Bass Rock by King James I of Scotland in 1427 for his part in the Battle of Harpsdale, which took place in 1426. Neil Wasse Mackay was released from the Bass Rock in 1436 and the following year raided Caithness in a repeat of the Battle of Harpsdale eleven years before. Battle The Mackays met the Caithness men at Dounreay () and pushed them to the Forss Water before Cai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dounreay Castle
Dounreay Castle is a ruined 16th-century L-plan castle, about west of Thurso, Highland (council area), Scotland, within the grounds of Dounreay Nuclear Power Development Establishment. It is also known as Dounreay House. The castle and its associated structures are a Scheduled Ancient Monument. History The castle is thought to date from the latter part of the 16th century. It was a property of the Sinclairs, the owner in 1614 being William Sinclair of Dunbeath, while in 1726 it was one of the lodgings of the Earl of Caithness. Ownership passed to the Forbeses, to the Mackays of Reay, and then to the Mackays of Tongue. Occupation continued until 1863, but the castle was unroofed and ruinous by 1910. The site was used a farm, with the courtyard being the farmyard, with the first of two ranges of cottages possibly being added south east of the castle in the 17th century. Cromwellian troops were housed in the castle in the mid-17th century. The site was leveled with the exception ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Decommissioning Authority
The Nuclear Decommissioning Authority (NDA) is a non-departmental public body of the Department for Business, Energy and Industrial Strategy, formed by the Energy Act 2004. It evolved from the Coal and Nuclear Liabilities Unit of the Department of Trade and Industry. It came into existence during late 2004, and took on its main functions on 1 April 2005. Its purpose is to deliver the decommissioning and clean-up of the UK's civil nuclear legacy in a safe and cost-effective manner, and where possible to accelerate programmes of work that reduce hazard. The NDA does not directly manage the UK's nuclear sites. It oversees the work through contracts with specially designed companies known as site licence companies. The NDA determines the overall strategy and priorities for managing decommissioning. Although the NDA itself employs about 250 staff, its subsidiaries employ about 15,000 staff across the NDA estate. Its annual budget is £3.2billion, the vast majority of which is spent th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fast Neutron Reactor
A fast-neutron reactor (FNR) or fast-spectrum reactor or simply a fast reactor is a category of nuclear reactor in which the fission chain reaction is sustained by fast neutrons (carrying energies above 1 MeV or greater, on average), as opposed to slow thermal neutrons used in thermal-neutron reactors. Such a fast reactor needs no neutron moderator, but requires fuel that is relatively rich in fissile material when compared to that required for a thermal-neutron reactor. Around 20 land based fast reactors have been built, accumulating over 400 reactor years of operation globally. The largest of this was the Superphénix Sodium cooled fast reactor in France that was designed to deliver 1,242 MWe. Fast reactors have been intensely studied since the 1950s, as they provide certain decisive advantages over the existing fleet of water cooled and water moderated reactors. These are: * More neutrons are produced when a fission occurs, resulting from the absorption of a fast neutron, than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DIDO (nuclear Reactor)
DIDO was a materials testing nuclear reactor at the Atomic Energy Research Establishment at Harwell, Oxfordshire in the United Kingdom. It used enriched uranium metal fuel, and heavy water as both neutron moderator and primary coolant. There was also a graphite neutron reflector surrounding the core. In the design phase, DIDO was known as AE334 after its engineering design number. DIDO was designed to have a high neutron flux, largely to reduce the time required for testing of materials intended for use in nuclear power reactors. This also allowed for the production of intense beams of neutrons for use in neutron diffraction. DIDO was shut down in 1990. The primary facilities decommissioning is expected to be complete in 2023 with the reactor decommissioning completed in 2031 and final site clearance achieved in 2064 In all, six DIDO class reactors were constructed based on this design: *DIDO, first criticality 1956. *PLUTO, also at Harwell, first criticality 1957. *HIFAR ...

Fast Breeder Reactor
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium-238 or thorium-232, that is loaded into the reactor along with fissile fuel. Breeders were at first found attractive because they made more complete use of uranium fuel than light water reactors, but interest declined after the 1960s as more uranium reserves were found,Helmreich, J.E. ''Gathering Rare Ores: The Diplomacy of Uranium Acquisition, 1943–1954'', Princeton UP, 1986: ch. 10 and new methods of uranium enrichment reduced fuel costs. Fuel efficiency and types of nuclear waste Breeder reactors could, in principle, extract almost all of the energy contained in uranium or thorium, decreasing fuel requirements by a factor of 100 compared to widely used once-through light water reactors, which extract less tha ...

Harwell Laboratory
The Atomic Energy Research Establishment (AERE) was the main centre for atomic energy research and development in the United Kingdom from 1946 to the 1990s. It was created, owned and funded by the British Government. A number of early research reactors were built here starting with GLEEP in 1947 to provide the underlying science and technology behind the design and building of Britain's nuclear reactors such as the Windscale Piles and Calder Hall nuclear power station. To support this an extensive array of research and design laboratories were built to enable research into all aspects of nuclear reactor and fuel design, and the development of pilot plants for fuel reprocessing. The site became a major employer in the Oxford area. In the 1990s demand for government-led research had significantly decreased and the site was subsequently gradually diversified to allow private investment, and was known from 2006 as the Harwell Science and Innovation Campus.
