The number of nuclear jobs on Anglesey has fallen to a record low, according to a new report.

The Nuclear Industry Association (NIA) says just 307 people are employed by the sector - down from 321 last year and less than half of the 795 jobs recorded a year ago.

Anglesey Council said it echoed the NIA's concerns about the decline of the nuclear sector in Wales and the urgent need for a new development at Wylfa.

Monday marked the fifth anniversary of Hitachi's announcement that it was withdrawing from plans to build a second nuclear reactor.

Council leader Gary Pritchard said: "The sharp decline in nuclear jobs on Ynys Môn has been worsened by repeated delays by UK Government to secure a new project at Wylfa."

"At its peak, the former Magnox station provided more than 1,400 good-quality jobs before decommissioning began in 2015, with communities across North Anglesey heavily reliant on that employment."

"The loss of other large employers such as Rehau and Octel in Amlwch has only deepened the economic challenges of the past two decades."

"With limited opportunities available, many working-age residents – often Welsh speakers – have left with their families, leaving behind an ageing population and increasing pressure on an already fragile local economy."

The council leader said Anglesey had "heard many words but little progress" since Hitachi's withdrawal in 2020.

Mr Pritchard called for "firm decisions" from the UK Government over a new nuclear development at Wylfa, which prior to last year's general election, had been chosen as the preferred site for a large-scale power plant, after being bought for £160 million in Hitachi.

He said: "The NIA's 2025 Jobs Map underlines what we have consistently said and lobbied for: a new nuclear development at Wylfa – whether at GW or SMR scale – is essential to the future prosperity of our Island, especially in North Anglesey."

"What is needed now from the UK Government is not further promises or false dawns, but firm decisions, clear timescales, and real delivery. The people of Anglesey deserve concrete action and a plan they can trust – not more false hopes."

Last year, a council report on the impact of the decommissioning of Wylfa - and the loss of other key employees - found North Anglesey had been in "protracted decline" over the last two decades.

Over a hundred jobs were lost with the closure of the Rehau plastics factory in Amlwch in 2019, while production ended at the nearby Octel bromine plant in 2004, with a 500-strong workforce being laid off.

Dylan J Williams, chief executive of Anglesey Council, added: "Anglesey faces challenges that cannot be addressed by the council and public sector alone."#

"Securing major private sector investment will be essential, and a new nuclear project at Wylfa represents the single greatest opportunity to deliver long-term, transformative change for the area."

"What we now require from the UK Government is certainty - a clear commitment that development will go ahead at Wylfa. That clarity will allow us to plan confidently, engage with our communities, and provide the assurances they rightly expect."

"At the same time, it is vital that any new project safeguards what makes Anglesey unique, including our Welsh language and culture, while creating a sustainable future for generations to come."
