Wylfa Nuclear Power Station
Wylfa Nuclear Power Station

Wylfa is a nuclear power station situated just west of Cemaes Bay on the island of Anglesey, north Wales. Located on the coast, the sea provides an excellent cooling source for its operation. Image File history File links Wylfapowerstation. ... Image File history File links Wylfapowerstation. ... A nuclear power plant (NPP) is a thermal power station in which the heat source is one or more nuclear reactors. ... Anglesey (Welsh: Ynys Môn, pronounced (IPA), roughly unniss mawn), is an island and county at the northwestern extremity of north Wales. ... For an explanation of often confusing terms such as Great Britain, Britain, United Kingdom, England and Wales and England, see British Isles (terminology). ...


It houses two 490 MW Magnox nuclear reactors, "Wylfa-1" and "Wylfa-2", which were built from 1963 and became operational in 1971. They have a combined capacity of 980 MW and Wylfa typically supplies 23 GW·h of electricity daily. It is the largest and last reactor of its type to be built in the UK. Magnox is an obsolesent type of nuclear power reactor; When operated on a short fuel cycle (which is uneconomic) they can also produce plutonium for nuclear weapons. ... Core of a small nuclear reactor used for research. ...


The graphite cores each weigh 3 800 tonnes. Over 6 000 vertical fuel channels contain 595 natural uranium channels together with a further 200 channels which allow boron control rods to enter the reactor. The primary coolant in the reactors is carbon dioxide (CO2) gas. Carbon dioxide is an atmospheric gas comprised of one carbon and two oxygen atoms. ...


It is anticipated that the Wylfa reactors will be shut down in 2010; however, there is a possibility the plant may be kept open a further few years.


The power station is operated by British Nuclear Fuels Limited. The site is owned by the Nuclear Decommissioning Authority (NDA). Its purpose is to oversee and manage the decommissioning and clean-up of the UK’s civil nuclear legacy. Categories: Government of the UK | Stub ... The Nuclear Decommissioning Authority (NDA) is a public body of the United Kingdom formed by the Energy Act, 2004. ...


A second plant (generally referred to as Wylfa B) has been proposed, in part to provide for the needs of the Anglesey Aluminium smelter located in Holyhead. This proposal has been the subject of local opposition, and the group People Against Wylfa B (PAWB) campaigns against it, and for the de-commissioning of the existing plant.

Visit Wylfa, Magnox Nuclear Power Station (475 words)
Wylfa Nuclear Power Station is situated just west of Cemaes, Anglesey, the northernmost village in Wales.
Wylfa covers and area of about 50 hectares and is located close to the sea, which provides an excellent cooling source for the plant's operation.
And secondly, Wylfa is a nuclear power station, which means the heat comes from splitting the nucleus ("core") of uranium atoms in the reactor.
Friends of the Earth Cymru: Press Release: 2003: Close Wylfa now (796 words)
Following the unpredicted shut down of both reactors at the Wylfa nuclear power station on Anglesey, seventeen reactors in Japan and an ongoing shut-down saga in the United States, environmental campaign group Friends of the Earth Cymru has criticised nuclear apologists for describing renewable energy technologies 'unreliable'.
The shut down of Wylfa's second reactor last Thursday (July 17th) follows the discovery of weld defects in reactor one's boiler tube support brackets.
Heat generated in the fuel rods is transferred by carbon dioxide gas to water inside the boiler tubes, which are often referred to as steam generators.
