Site profile
Wylfa Site is an operational power station on a 20.79 hectare site on the north coast of Anglesey between Holyhead and Amlwch. The site has two Magnox design nuclear reactors and four turbine generators. It meets more than 40% of Wales' electricity needs and on a typical day, the station supplies 23 million kilowatt hours of electricity, enough to meet the needs of a city, twice the size of Liverpool and Manchester combined.
Our primary objective at the site as the tier 1 management and operations contractor is to continue to generate electricity to the national grid for public consumption as well as maximise economic return, while maintaining a safe and secure working environment. At the same time, we are preparing the power station for a seamless transition to the defuelling phase, the start of the power station’s decommissioning programme.
Magnox North is the management and operations contractor responsible for the day-to-day operation of the site under contract to the Nuclear Decommissioning Authority.
