Welsh Secretary Alun Cairns says he remains confident Wylfa Newydd will still get built and wants to push on with the Development Consent Order(DCO).
Hitachi announced on Thursday that it was putting the £12bn Wylfa Newydd development on hold after failing to reach a funding agreement with the UK Government.
The Secretary of State for Wales Alan Cairns came to Anglesey on Friday to meet representatives of Hitachi and Horizon Nuclear Power and local politicians.
He said that while he accepted the project would be delayed he still believed the massive infrastructure scheme near Cemaes would happen.

Mr Cairns said he wanted to push on with the planning process.
Horizon submitted the DCO last summer in its bid to secure permission to develop the site.
He said: "We all agreed, including Hitachi and Horizon, that we need to maintain momentum. That will limit the delay in the construction of the site.
"We are working to a three stage plan.
"One is to gain Horizon and Hitachi's commitment towards the Development Consent Order process.

"That involves additional expenditure but will limit any delay.
"The second element is to revisit the North Wales Growth Deal, recalibrate it in relation to the latest announcements."
He added: "The third is to have that dialogue with National Grid so that we can look to see what their commitments are and influence them positively to put us in the best position so that when a re-financed package comes forward Wylfa Newydd will be back on track."

National Grid has announced it has put its plan to build pylons across Anglesey to link to the power station on hold.
It is estimated that the failure to develop Wylfa Newydd will deliver a £5.7bn hit to the Welsh economy - halting plans to create 9,000 roles at peak construction and up to 1,000 long term jobs.
The UK Government had put together a funding package to offer Hitachi but it was not enough to persuade them to push on with the development.
