Springfields is a nuclear fuel production installation in Salwick, near Preston in Lancashire, England (grid reference SD468315). The site is currently operated by Springfields Fuels Limited, under the management of Westinghouse Electric UK Limited, on a 150-year lease from the Nuclear Decommissioning Authority.[2] Since its conversion from a munitions factory in 1946, it has previously been operated and managed by a number of different organisations including the United Kingdom Atomic Energy Authority and British Nuclear Fuels.[3] Fuel products are produced for the UK's nuclear power stations and for international customers.[4]

Activities on the siteEdit

The site has been making nuclear fuels since the mid-1940s. The site is notable for being the first nuclear plant in the world to produce Magnox fuel for a commercial power station (Calder Hall).[3][4]

The four main activities carried out on the site are:[5][4]

At its peak the site employed 4000 people, but reduced demand and increased automation saw this fall to about 800 by 2020.[4]

Future of the plantEdit

Manufacture is scheduled to continue until 2023. Decommissioning activities have so far resulted in 87 buildings on the site having been fully demolished.[6] A Clean Energy Technology Park (CETP) has been set up to encourage new companies to operate on the site.[4]
