Springfields is a nuclear fuel production installation in Salwick, near Preston in Lancashire, England (grid reference SD468315).

[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.

The site is notable for being the first nuclear plant in the world to produce Magnox fuel for a commercial power station (Calder Hall).

[4] In December 2022 Westinghouse received a £13 million grant from the UK government to explore the development of Uranium Conversion Services at the site.

[7] A Clean Energy Technology Park (CETP) has been set up to encourage new companies to operate on the site.
