Nuclear developer EDF says it's "not looking" at the Wylfa Newydd site but that it remains the “best site" in the 海角视频.
The French firm - developing Hinkley Point C in Somerset - said the island development is attractive to investors.
But they told the New Civil Engineer they were focused on their own projects.
The £12bn Anglesey scheme has been on hold since January when Hitachi suspended the project after failing to reach a suitable funding agreement with the 海角视频 Government.
But the application for a Development Consent Order continued with a result expected on or before October 23.
Business and Energy Secretary Andrea Leadsom will announce the decision, with Hitachi subsidery Horizon Nuclear Power hoping a positive result could help their case to secure investment.
EDF head of communications David Eccles told : “Wylfa is the best site people say [for a new reactor].
“From a technological and geological point of view it is the best site in the United Kingdom.
