A nuclear power company is looking for partners to develop new generators on sites where it already operates.
Sizewell B was built between 1988 and 1995
British Energy, which also owns coal-fired power stations and wind farms, is offering development land close to existing nuclear power plants.
It owns land at the Sizewell B plant in Suffolk and next to Bradwell in Essex.
Land is also available at Hunterston and Torness in Scotland, Heysham in Lancashire, Hartlepool on Teesside and Hinkley Point in Somerset.
A British Energy spokeswoman said: "We are waiting for the government white paper on the future of energy generation to find out what role nuclear generation is to play.
"But we believe nuclear power is needed as part of the solution to ensuring security of energy supply and because it is virtually carbon dioxide emission free it does not add to climate change.
"We are now waiting for guidance from the government before moving forward to new build but are looking for partners in preparation."
