Wylfa Newydd Nuclear Power Station
Wylfa Newydd nuclear power station, also known as Wylfa B, was a proposed project to construct a 2,700 MWe nuclear power station with two ABWR reactors in Anglesey, Wales. The project was owned by Horizon Nuclear Power which is a subsidiary of Hitachi, who are also the main shareholder in Hitachi-GE Nuclear Energy, the supplier of the reactors for the project. Hitachi withdrew from the project in September 2020. History In 2008, the government decided that new nuclear sites should be constructed on existing sites to replace the UK's ageing fleet of reactors. In 2010, the government revealed that Wylfa was one of the 8 sites that it intended to allow the development to occur at. Horizon Nuclear Power was set up on 14 January 2009 by E.ON UK and RWE npower as a 50:50 joint venture, with the aim to develop at least 6 GW of nuclear capacity in the UK. Following the establishment of the joint venture, the UK government set up an auction for three of the sites, Wylfa, Old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnox
Magnox is a type of nuclear power/production reactor that was designed to run on natural uranium with graphite as the moderator and carbon dioxide gas as the heat exchange coolant. It belongs to the wider class of gas-cooled reactors. The name comes from the magnesium-aluminium alloy used to clad the fuel rods inside the reactor. Like most other " Generation I nuclear reactors", the Magnox was designed with the dual purpose of producing electrical power and plutonium-239 for the nascent nuclear weapons programme in Britain. The name refers specifically to the United Kingdom design but is sometimes used generically to refer to any similar reactor. As with other plutonium-producing reactors, conserving neutrons is a key element of the design. In magnox, the neutrons are moderated in large blocks of graphite. The efficiency of graphite as a moderator allows the Magnox to run using natural uranium fuel, in contrast with the more common commercial light-water reactor which re ...

Advanced Boiling Water Reactor
The advanced boiling water reactor (ABWR) is a Generation III boiling water reactor. The ABWR is currently offered by GE Hitachi Nuclear Energy (GEH) and Toshiba. The ABWR generates electrical power by using steam to power a turbine connected to a generator; the steam is boiled from water using heat generated by fission reactions within nuclear fuel. Kashiwazaki-Kariwa unit 6 is considered the first Generation III reactor in the world. Boiling water reactors (BWRs) are the second most common form of light water reactor with a direct cycle design that uses fewer large steam supply components than the pressurized water reactor (PWR), which employs an indirect cycle. The ABWR is the present state of the art in boiling water reactors, and is the first Generation III reactor design to be fully built, with several reactors complete and operating. The first reactors were built on time and under budget in Japan, with others under construction there and in Taiwan. ABWRs were on order ...
