Fuel Manufacturing

Fuel used in nuclear reactors in the UK and overseas to generate electricity is made at our Springfields site. The raw material used to make nuclear fuel is uranium rock mined all over the world, with the ore taken containing about 1.5% uranium. To concentrate the uranium content, the ore is ground, treated and purified using chemical and physical processes. This results in a uranium ore concentrate that contains around 80% uranium.


  • Springfields Fuels Limited is the site licence company for the Springfields site.
  • Springfields has been safely making nuclear fuel since 1946 and has the facilities to manufacture fuel for most types of nuclear reactors.
  • Springfields was the first plant in the world to make nuclear fuel for commercial power stations and has produced several million fuel elements, supplying products and services for reactors in 11 countries.
  • Around 32% of the UK’s low carbon electricity comes from fuel manufactured at Springfields.
  • Springfields was the first nuclear site in the UK to put a Biodiversity Action Plan in place to manage the site’s environmental areas, with the site containing two Biological Heritage Sites.

Advanced Nuclear Technology

The wide variety of advanced nuclear technologies and related industrial and medical applications currently under development will define the future of clean energy and nuclear medicine in the UK and globally. There are clear synergies apparent across these technologies, and their future deployment across power generation, industrial applications, nuclear clean-up and medical uses.
