Big step in 10 year Wylfa Newydd nuclear power project
Plans for an £8bn nuclear power station on Anglesey go on display later with a series of exhibitions over ten weeks.
Horizon Nuclear Power says its proposed Wylfa Newydd power plant will employ more than 1,000 people once it begins working in the first half of the 2020s.
The current Wylfa power station will close in 2015 at the latest, after beginning operation in 1971.
Horizon is a subsidiary of Hitachi which bought the site in 2012 for around £700m.
Environment Iolo ap Dafydd said it is a significant landmark on the road to the plant opening, which could take 10 years.
