Llyn Trawsfynydd
Llyn Trawsfynydd is a large man-made reservoir situated near the village of Trawsfynydd in Gwynedd, North Wales. With a total surface area of the reservoir is slightly more extensive than Wales's largest natural lake, Llyn Tegid at . History The lake was created between 1924 and 1928 by building four dams in order to supply water for Maentwrog power station Maentwrog power station was built by the North Wales Power Company and supplied electricity to North Wales, Deeside and Cheshire. It exploits the water resources of the Snowdonia mountains, using water turbines to drive electricity alternators. T .... More than twenty properties, some of historical significance, were lost in the creation of the lake but there was little local objection at the time. Included were at least two farms, Brynhir and Llwynderw. Indeed, the power station was regarded as a good thing because it could supply the whole of North Wales' electricity needs. However local landowners and farmers did o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gwynedd
Gwynedd (; ) is a county and preserved county (latter with differing boundaries; includes the Isle of Anglesey) in the north-west of Wales. It shares borders with Powys, Conwy County Borough, Denbighshire, Anglesey over the Menai Strait, and Ceredigion over the River Dyfi. The scenic Llŷn Peninsula and most of Snowdonia National Park are in Gwynedd. Bangor is the home of Bangor University. As a local government area, it is the second largest in Wales in terms of land area and also one of the most sparsely populated. A majority of the population is Welsh-speaking. ''Gwynedd'' also refers to being one of the preserved counties of Wales, covering the two local government areas of Gwynedd and Anglesey. Named after the old Kingdom of Gwynedd, both culturally and historically, ''Gwynedd'' can also be used for most of North Wales, such as the area that was policed by the Gwynedd Constabulary. The current area is , with a population of 121,874 as measured in the 2011 Census. Et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam A dam is a barrier that stops or restricts the flow of surface water or underground streams ...

Ceunant Llennyrch National Nature Reserve
Ceunant Llennyrch National Nature Reserve is one of several woodland reserves in the Vale of Ffestiniog in Gwynedd, Wales and runs from Llyn Trawsfynydd to the River Dwyryd, near the village of Maentwrog. The reserve's broad expanse of woodland coats a steep-sided gorge, through which the Afon Prysor cascades. At one point, the river is flanked by high cliffs, which face each other only apart. The high humidity offered by the falls creates the perfect environment for numerous damp-loving plants, due to the high humidity and high rainfall, it is technically a temperate rainforest. Background In December 2015, the forest was bought for a price of £1 million by The Woodland Trust. The woodland has been there since the last ice age, and is so deep that apparently, some parts are untouched by humans. Flora The forest is exceptionally damp, creating the perfect habitat for nature to flourish. There are over 200 species of liverwort, many forms of moss and lichen too. Trees inc ...

Bala Lake
Bala Lake ( cy, Llyn Tegid ) is a large freshwater glacial lake in Gwynedd, Wales. The River Dee, which has its source on the slopes of Dduallt in the mountains of Snowdonia, feeds the long by wide lake. It was the largest natural body of water in Wales before its level was raised by Thomas Telford to provide water for the Ellesmere Canal (later Llangollen Canal). The town of Bala, which was once an important centre for the North Wales woollen trade, is located on the north-eastern end of the lake. The narrow gauge Bala Lake Railway, between the town and Llanuwchllyn (whose name means "church llan'above uwch'the lake llyn'), runs along the lake's south-eastern shore using a section of former trackbed from the former Ruabon–Barmouth line. Toponyms Previous names Gerald of Wales records the lake in his 12th century ''Itinerarium Cambriae'' under the name ''Penmelesmere''. In his 1804 translation of Gerald's work, Sir Richard Colt Hoare states that the lake was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maentwrog Power Station
Maentwrog power station was built by the North Wales Power Company and supplied electricity to North Wales, Deeside and Cheshire. It exploits the water resources of the Snowdonia mountains, using water turbines to drive electricity alternators. The 24MW station has been owned by several organisations; since 2004 it has been owned by the Nuclear Decommissioning Authority. It generates an annual electricity output of 60.6GWh. History Maentwrog hydro-electric power station was first commissioned in October 1928 by the North Wales Power Company Limited. The company also owned Dolgarrog and Cwm Dyli power stations. The new station was financed by the issue of £1.7million of debenture stock in 1924. The architectural design of the power house was by Sir Alexander Gibb and Partners. To power the station a new reservoir was built at Trawsfynydd, formed by the construction of four dams. The main dam on the Afon Prysor was Britain's first large arch dam. The other three cut off dams were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trawsfynydd Nuclear Power Station
Trawsfynydd nuclear power station ( cy, Atomfa Trawsfynydd) is a decommissioned Magnox nuclear power station situated in Snowdonia National Park in Gwynedd, Wales. The plant, which became operational in 1965, was the only nuclear power station in the UK to be built inland, with cooling water that was taken from the man-made Llyn Trawsfynydd reservoir which also supplies the hydro-electric Maentwrog power station. It was closed in 1991. Its planned decommissioning by Magnox Ltd was expected to take almost 100years, but in 2021 the Welsh government arranged for the power station to be redeveloped using small-scale reactors. History The power station, which takes its name from the nearby village of Trawsfynydd, was designed by Basil Spence. The construction, which was undertaken by a consortium involving Crompton Parkinson, International Combustion, Fairey Engineering and Richardsons Westgarth, and known as the Atomic Power Constructions (APC), began in July 1959, and both of the ...

National Grid (UK)
In the electricity sector in the United Kingdom, the National Grid is the high-voltage electric power transmission network serving Great Britain, connecting power stations and major substations and ensuring that electricity generated anywhere on it can be used to satisfy demand elsewhere. The network covers the great majority of Great Britain and several of the surrounding islands. It does not cover Northern Ireland, which is part of a single electricity market with the Republic of Ireland. The GB grid is connected as a wide area synchronous grid nominally running at 50 hertz. There are also undersea interconnections to other grids in the Isle of Man, Northern Ireland, the Republic of Ireland, France, Belgium, the Netherlands and Norway. On the breakup of the Central Electricity Generating Board in 1990, the ownership and operation of the National Grid in England and Wales passed to National Grid Company plc, later to become National Grid Transco, and now National Grid plc.

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] |
