Windscale Advanced Gas Cooled Reactor
Sellafield is a large multi-function nuclear site close to Seascale on the coast of Cumbria, England. As of August 2022, primary activities are nuclear waste storage, nuclear waste processing and storage and nuclear decommissioning. Former activities included nuclear power generation from 1956 to 2003, and nuclear fuel reprocessing from 1952 to 2022. Reprocessing ceased on 17 July 2022, when the Magnox Reprocessing Plant completed its last batch of fuel after 58 years of operation. The licensed site covers an area of , and comprises more than 200 nuclear facilities and more than 1,000 buildings. It is Europe's largest nuclear site and has the most diverse range of nuclear facilities in the world situated on a single site. The site's workforce size varies, and before the COVID-19 pandemic was approximately 10,000 people. The UK's National Nuclear Laboratory has its Central Laboratory and headquarters on the site. Originally built as a Royal Ordnance Factory in 1942, the site br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seascale
Seascale is a village and civil parish on the Irish Sea coast of Cumbria, England, historically within Cumberland. The parish had a population of 1,747 in 2001, barely increasing by 0.4 % in 2011. History The place-name indicates that it was inhabited by Norse settlers, probably before 1000 AD. It is derived from ''skali'', meaning in Norse a wooden hut or shelter. This could well date from the time of King Harold Fairhair, who vowed revenge on the many Norsemen who had settled in Ireland and the Isle of Man, causing them to flee across the sea to the Cumbrian coast some time after AD 885. Many other Norse place names are to be found, including Seascale How, ''Skala Haugr'', (the hill near the shelter), and Whitriggs, ''hvitihrgger'' (the white ridge). As the Norse penetrated inland other skalar were named, so Seascale was distinguished by reference to the sea. The earliest written reference to Seascale is in the period 1154–1181, when an Aldwin de Seascale was witness to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plutonium
Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthetically produced and isolated in late 1940 and early 1941, by a deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 (half-life 2.1 days) was synthesized, which subsequently beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years) ...

Wastwater
Wast Water or Wastwater () is a lake located in Wasdale, a valley in the western part of the Lake District National Park, England. The lake is almost long and more than wide. It is a glacial lake, formed in a glacially 'over-deepened' valley. It is the deepest lake in England at . The surface of the lake is about above sea level, while its bottom is over below sea level. It is owned by the National Trust. Surroundings The head of the Wasdale Valley is surrounded by some of the highest mountains in England, including Scafell Pike, Great Gable and Lingmell. The steep slopes on the southeastern side of the lake, leading up to the summits of Whin Rigg and Illgill Head, are known as the "Wastwater Screes" or on some maps as "The Screes". These screes formed as a result of ice and weathering erosion on the rocks of the Borrowdale Volcanic Group, that form the fells to the east of the lake, towards Eskdale. They are approximately , from top to base, the base being about below th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Explosive ROF
An Explosive ROF was a UK Government-owned Royal Ordnance Factory (ROF), which specialised in manufacturing explosives during and after World War II. Note: In World War I, the name used in the UK for Government-owned explosives factories was National Explosives Factory; and the Cordite factory at Gretna was known as HM Factory, Gretna. These Second World War factories were built for the Ministry of Supply with the Ministry of Works, in all cases except ROF Irvine, acting as agent. Explosive ROF's specialised in producing either high-explosives, such as TNT (trinitrotoluene) or RDX; or propellants, such as cordite, but there were minor exceptions to this demarcation. The products from these Explosive ROFs were shipped to Filling Factories for filling into munitions. Pyrotechnics, such as fuzes and screening smokes, tended to be made at the Filling Factories and filled directly into munitions. Comparable WW II factories not part of the ROF organisation ICI and Ministry o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Laing Group
John Laing Group plc is a British investor, developer and operator of privately financed, public sector infrastructure projects such as roads, railways, hospitals and schools through Public-Private Partnership (PPP) and Private Finance Initiative (PFI) arrangements. It was listed on the London Stock Exchange and was a constituent of the FTSE 250 Index until the court approved the acquisition of the company by KKR in September 2021. History The business can trace its roots back to 1848 when James Laing (born in 1816), along with his wife Ann Graham, and some employees whom they had hired, built a house on a plot of land that they had bought for £30 in Cumberland. The £150 proceeds from the first house financed the building of the next two houses on the same plot of land, one of which (Caldew House in Sebergham) was kept by the Laing family to live in. The family and the business later moved near Carlisle. When James Laing died in 1882, his son, John Laing (born in 1842) took ove ...

International Nuclear Event Scale
The International Nuclear and Radiological Event Scale (INES) was introduced in 1990 by the International Atomic Energy Agency (IAEA) in order to enable prompt communication of safety significant information in case of nuclear accidents. The scale is intended to be logarithmic, similar to the moment magnitude scale that is used to describe the comparative magnitude of earthquakes. Each increasing level represents an accident approximately ten times as severe as the previous level. Compared to earthquakes, where the event intensity can be quantitatively evaluated, the level of severity of a man-made disaster, such as a nuclear accident, is more subject to interpretation. Because of this subjectivity the INES level of an incident is assigned well after the fact. The scale is therefore intended to assist in disaster-aid deployment. Details A number of criteria and indicators are defined to assure coherent reporting of nuclear events by different official authorities. There a ...

Cancers
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans. Tobacco use is the cause of about 22% of cancer deaths. Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol. Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants. In the developing world, 15% of cancers are due to infections such as '' Helicobacter pylori'', hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV). These factors act, at least partly, by changing the genes of a cel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windscale Fire
The Windscale fire of 10 October 1957 was the worst nuclear accident in the United Kingdom's history, and one of the worst in the world, ranked in severity at level 5 out of a possible 7 on the International Nuclear Event Scale. The fire was in Unit 1 of the two-pile Windscale site on the north-west coast of England in Cumberland (now Sellafield, Cumbria). The two graphite-moderated reactors, referred to at the time as "piles," had been built as part of the British post-war atomic bomb project. Windscale Pile No. 1 was operational in October 1950, followed by Pile No. 2 in June 1951. The fire burned for three days and released radioactive fallout which spread across the UK and the rest of Europe. The radioactive isotope iodine-131, which may lead to cancer of the thyroid, was of particular concern at the time. It has since come to light that small but significant amounts of the highly dangerous radioactive isotope polonium-210 were also released. It is estimated that the rad ...

List Of Nuclear And Radiation Accidents By Death Toll
There have been several nuclear and radiation accidents involving fatalities, including nuclear power plant accidents, nuclear submarine accidents, and radiotherapy incidents. List of accidents Events with disputed fatality counts Chernobyl disaster Estimates of the total number of deaths potentially resulting from the Chernobyl disaster vary enormously: A UNSCEAR report proposes 45 total confirmed deaths from the accident . This number includes 2 non-radiation related fatalities from the accident itself, 28 fatalities from radiation doses in the immediate following months and 15 fatalities due to thyroid cancer likely caused by iodine-131 contamination; it does not include 19 additional individuals initially diagnosed with acute radiation syndrome who had also died , but who are not believed to have died due to radiation doses. The World Health Organization (WHO) suggested in 2006 that cancer deaths could reach 4,000 among the 600,000 most heavily exposed people, a group whi ...

Non-departmental Public Body
In the United Kingdom, non-departmental public body (NDPB) is a classification applied by the Cabinet Office, Treasury, the Scottish Government and the Northern Ireland Executive to public sector organisations that have a role in the process of national government but are not part of a government department. NDPBs carry out their work largely independently from ministers and are accountable to the public through Parliament; however, ministers are responsible for the independence, effectiveness and efficiency of non-departmental public bodies in their portfolio. The term includes the four types of NDPB (executive, advisory, tribunal and independent monitoring boards) but excludes public corporations and public broadcasters ( BBC, Channel 4 and S4C). Types of body The UK Government classifies bodies into four main types. The Scottish Government also has a fifth category: NHS bodies. Advisory NDPBs These bodies consist of boards which advise ministers on particular policy area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
