Revised Wylfa nuclear plant designs released

Wylfa Newydd nuclear power station

Streamlining construction is the driving force behind new designs for the Wylfa Newydd nuclear power plant, released for a third consultation.

Horizon Nuclear Power (HNP) has unveiled a more condensed design for the Welsh plant. It will have more power facilities shared between the twin reactors and more components earmarked for modular construction, to keep down costs.

Although the number of workers expected on site at peak has dropped from 10,000 to 8,500 as a result, more worker accommodation will be included to reduce pressure on businesses and communities in Anglesey.

Two consultations about designs for the plant have already been held. HNP, owned by Japanese firm Hiatchi, is focusing its latest proposal on areas which have changed.

“The changes we’re proposing will enable us to streamline our construction schedule, reduce the number of construction workers we need to bring in and temporarily house, and cut the number of development sites we need,” said Horizon Nuclear Power chief executive Duncan Hawthorne

“Alongside this we remain absolutely committed to being a good neighbour to the North Anglesey communities which will host the power station.”

Changes to the design will not affect the power plant’s schedule, with the first unit due at the end of 2025, assuming the project is granted a development consent order.

Improvements to the A5025 road will still go ahead as stated in previous consultations, as will support for Welsh language protection.

HNP confirmed last year that Menter Newydd, a joint venture of US giant Bechtel, Japanese firm JGC Corporation and Hitachi Nuclear Energy, is to deliver the Wylfa Newydd nuclear power station.
