The current Wylfa station is due to stop producing electricity in 2010
A new nuclear power station on Anglesey has moved a step closer after the UK government announced a list of 10 approved sites.
The inclusion of the site at Wylfa has been welcomed by the county council and Welsh Secretary Peter Hain.
Campaign group Pawb (People Against Wylfa B) said more should be done to find alternative sources of power.
The current Wylfa power station has permission to continue electricity production until December 2010.
As well as Wylfa, Energy and Climate Change Secretary Ed Miliband announced that other sites deemed suitable are Bradwell in Essex, Braystones, Kirksanton and Sellafield in Cumbria, Hartlepool, Heysham in Lancashire, Hinkley Point in Somerset, Oldbury in Gloucestershire, and Sizewell in Suffolk.
Anglesey council leader Clive McGregor said the announcement would give the potential developers JV - Horizon and RWE npower/e-on confidence to progress with their schedule for Wylfa.
He said the significance of the potential investment should not be underestimated as it was "in the region of £8bn".
"This is comparable to the investment in London in preparation for the 2012 Olympics," he said.
"We must make the most of this opportunity to safeguard long-term employment on the island," he added.
A 14-week consultation period will follow the announcement of the list of potential sites.
Bryan Owen, holder of the economic development portfolio holder on Anglesey council, said it was important for everyone to have their say "whatever their stance on nuclear new build".
Public consultation events will take place on Anglesey in January 2010.
"It is important for the regional economy, and our communities, that Wylfa is part of the first wave of new nuclear developments if we are to capitalise fully on the availability of transferable skills in the area," he added.
Mr Hain said: "After the devastating blow to the island with the closure of Anglesey Aluminium recently, a new nuclear build with the jobs and investment it could provide would be a massive boost to the local economy".
Mr Hain added the island was already "proven" as suitable for nuclear generations, as the current Wylfa station had been operating for 40 years.
"However that facility is due to close and it is important for the energy security of our country that we get a new nuclear round of building started as soon as possible," he said.
"A new nuclear power station at Wylfa will provide us with a stable energy mix which includes renewable generation such as wind and tidal, as well as our investment in clean coal technology," he added.
