Prime Minister Boris Johnson says "very serious conversations" are taking place with two US energy and engineering giants over bringing a nuclear power plant to Anglesey.
Horizon/Hitachi withdrew from developing the Wylfa site after failing to reach a deal with UK Government on funding the project.
But hopes of bringing reactors and hundreds of jobs to the site have not been abandoned - with MP Virginia Crosbie among those pressing the case for the island.
Prime Minister Boris Johnson was yesterday on Anglesey and visited Wylfa, near Cemaes.
He said: "We went to look at the Wylfa site, it has great potential.
"Thanks to the work of Virginia(Crosbie, Ynys Mon MP) , an outstanding MP, there are very serious conversations going on with Westinghouse and Bechtel about what to do.
"We are also supporting a programme of small modular reactors and we'll have to see where we get to, I'm very enthusiastic but we need the private sector to come in and do it.
"We are going to work very hard to make it happen.
"You can see the potential at the site for creating long term sustainable jobs and a huge amount of clean green power, it's a fantastic vision and we are right on it. It is a very interesting prospect."
Westinghouse says the Anglesey site is the “perfect location” for a new nuclear site while partner Bechtel, a US engineering giant, has a proposal in place.
Meanwhile Rolls Royce is leading a consortium developing small modular reactors - with Trawsfynydd in Gwynedd and Wylfa potential host sites.
