Seascale railway station

Seascale Lifeboat Station was located in Seascale, a village overlooking the Irish Sea, approximately 13 miles (21 km) south of Whitehaven, in the county of Cumberland, Cumbria. Also known as Whitehaven No.2 Lifeboat Station, a lifeboat station was established at Seascale by the Royal National Lifeboat Institution (RNLI) in 1875. After very few launches, and only one successful rescue, Seascale Lifeboat Station closed in 1895.

St Cuthbert's is in Seascale, Cumbria, England. It is an active Anglican parish church in the deanery of Calder, and the diocese of Carlisle. Its benefice is Seatallan. The church is a Grade II Listed Building.

Seascale is a village and civil parish on the Irish Sea coast of Cumbria, England, historically within Cumberland. The parish had a population of 1,754 in 2011, barely decreasing by 0.4% in 2021.

Grey Croft stone circle is a restored stone circle near Seascale in Cumbria, England (grid reference NY03340238). It is situated near the site of the former nuclear-power stations at Sellafield.

Calder is a small hamlet in Cumbria, England. It is overlooked by the Sellafield nuclear plant—Calder Hall Nuclear Power Station was the world's first major nuclear power station when it opened in 1956.

Calder Hall Nuclear Power Station is a former Magnox nuclear power station on the Sellafield site in Cumbria in North West England. Calder Hall was the first full-scale nuclear power station to enter operation in the World, and was the sister plant to the Chapelcross plant in Scotland. Both were commissioned and originally operated by the United Kingdom Atomic Energy Authority. The primary purpose of both plants was to produce weapons-grade plutonium for the UK's nuclear weapons programme, but they also generated electrical power for the National Grid. Decommissioning by Sellafield Ltd started in 2005. The site is partially demolished and is expected that only the reactor cores and associated radiation shielding will remain by 2027, when it will enter a period of extended care and maintenance using the "safestore" principle, before final demolition.

The River Calder is a river in Cumbria, England. The river rises at Lankrigg Moss and flows southwards for 10 miles (16 km) through an ancient landscape, flowing under Monks Bridge (a packhorse bridge) and by the site of Calder Abbey, as well as several tumuli and other mysterious monuments. It also runs past and (indirectly) gives its name to Calder Hall, site of the world's first commercial nuclear reactor. Near its mouth the river runs through the Sellafield nuclear site in an artificially straightened section before flowing into the Irish Sea at the same point as the River Ehen, just southwest of Sellafield.

The Magnox Reprocessing Plant is a former nuclear reprocessing facility at Sellafield in northern England, which operated from 1964 to 2022. The plant used PUREX chemistry (based on tributyl phosphate (TBP)) to extract plutonium and uranium from used nuclear fuel originating primarily from Magnox reactors. The plant was originally constructed and operated by the United Kingdom Atomic Energy Authority (UKAEA), but in 1971 control was transferred to British Nuclear Fuels Limited (BNFL). From 2005 the plant was operated by Sellafield Ltd.

The Thermal Oxide Reprocessing Plant, or THORP, is a nuclear fuel reprocessing plant at Sellafield in Cumbria, England. THORP is owned by the Nuclear Decommissioning Authority and operated by Sellafield Ltd, the site licensee. Spent nuclear fuel from nuclear reactors was reprocessed to separate the 96% uranium and the 1% plutonium from the 3% radioactive wastes, which are treated and stored at the plant. The uranium is then made available for customers to be manufactured into new fuel, and the plutonium incorporated into mixed oxide fuel. On 14 November 2018 it was announced that reprocessing operations had ended at THORP after earning £9bn in revenue. The receipt and storage facility (which makes up nearly half of THORP's physical footprint), will operate through to the 2070s to receive and store spent nuclear fuel from the UK's PWR and AGR fleet. The decommissioning is expected to start around 2075.

The Windscale Advanced Gas Cooled Reactor (WAGR) was a nuclear power plant constructed on the Sellafield nuclear site in Cumbria, England.

Sellafield, formerly known as Windscale, 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 processing and storage and nuclear decommissioning. Former activities included nuclear power generation from 1956 to 2003, and nuclear fuel reprocessing from 1952 to 2022. The licensed site covers an area of 265 hectares (650 acres), 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 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 briefly passed into the ownership of Courtaulds for rayon manufacture following World War II, but was re-acquired by the Ministry of Supply in 1947 for the production of plutonium for nuclear weapons which required the construction of the Windscale Piles and the First Generation Reprocessing Plant, and it was renamed "Windscale Works". Subsequent key developments have included the building of Calder Hall nuclear power station - the world's first nuclear power station to export electricity on a commercial scale to a public grid, the Magnox fuel reprocessing plant, the prototype Advanced Gas-cooled Reactor (AGR) and the Thermal Oxide Reprocessing Plant (THORP). Decommissioning projects include the Windscale Piles, Calder Hall nuclear power station, and historic reprocessing facilities and waste stores. The site is owned by the Nuclear Decommissioning Authority (NDA) which is a non-departmental public body of the UK government. Following a period 2008–2016 of management by a private consortium, the site was returned to direct government control by making the Site Management Company, Sellafield Ltd, a subsidiary of the NDA. Decommissioning of legacy facilities, some of which date back to the UK's first efforts to produce an atomic bomb, is planned for completion by 2120 at a cost of £121 billion. Sellafield was the site in 1957 of the UK's worst nuclear accident. This was the Windscale fire which occurred when uranium metal fuel ignited inside Windscale Pile no.1. Radioactive contamination was released into the environment, it has been estimated that this caused around 240 cancers in the long term, with 100 of these predicted to be fatal, though epidemiological studies have failed to find any such increase. The incident was rated 5 out of a possible 7 on the International Nuclear Event Scale.

The Windscale Piles were two air-cooled graphite-moderated nuclear reactors on the Windscale nuclear site in Cumberland (now known as Sellafield site, Cumbria) on the north-west coast of England. The two reactors, referred to at the time as "piles", were built as part of the British post-war atomic bomb project and produced weapons-grade plutonium for use in nuclear weapons. Windscale Pile No. 1 became operational in October 1950 followed by Pile No. 2 in June 1951. They were intended to last five years, but operated for seven until shut down following the Windscale fire on 10 October 1957. Nuclear decommissioning operations commenced in the 1980s and are estimated to last beyond 2040. Visible changes have been seen as the chimneys were slowly dismantled from top-down; Pile 2's chimney being reduced to the height of adjacent buildings in the early 2000s. However, the demolition of pile 1 chimney has taken much longer as it was significantly contaminated after the 1957 fire. The reactor cores still remain to be dismantled.
