A decade ago, the once-mighty Wylfa nuclear turbines on Anglesey fell silent, marking the end of an era for Wales' nuclear energy production. But here's the shocking truth: the island has struggled to recover ever since, grappling with job losses, stagnant investment, and an economy desperately seeking to replace one of its largest employers. This is the story of Wylfa's rise, fall, and the ongoing debate about its future.
Opened in 1971 as Wales' second Magnox power station, Wylfa brought industrial transformation to Anglesey, a Welsh-speaking island historically dominated by agriculture. Its strategic location on the northern coast allowed seawater to serve as an ideal coolant. Coinciding with the establishment of Anglesey Aluminium in nearby Holyhead, this period ushered in long-term, skilled employment opportunities. But this is the part most people miss: while Wylfa operated beyond its planned lifespan, becoming one of the world's oldest reactors by the early 2010s, its closure in 2015 left a void that Anglesey is still struggling to fill.
Gron Williams, a 76-year-old Holyhead resident, spent his entire working life at Wylfa, starting as a teenage apprentice in 1965. He vividly recalls the construction phase: 'You saw this big hole being dug, tunnels going out under the sea, and massive steel spheres being welded together. It was incredibly exciting.' Williams witnessed the economic transformation: 'People could afford homes, start businesses – there was a noticeable increase in wealth.' Yet, despite extensions, the second reactor shut down in 2012, followed by Reactor 1 on December 30, 2015, ending 44 years of operation. Williams, then a shift charge engineer, was in the control room when the power was finally cut. 'It was the end of an era,' he said, reflecting on the inevitable job losses as decommissioning began.
Here’s where it gets controversial: While decommissioning has provided some employment, with around 260 people still working on-site, Anglesey has 'paid the price' for failing to secure a replacement before Wylfa's closure. Welsh, the predominant language at the plant, is now less central to the island's economy. Stuart Law, Site Director, notes that 99.9% of radiation has been removed, and the focus is now on asbestos removal and dismantling unnecessary structures. Ffion Morris, the engineering and maintenance manager, highlights the shift from electricity generation to ethical decommissioning: 'It’s about ensuring we leave a safe site for future generations.'
But the debate doesn’t end there. While plans for Wylfa Newydd, a £20bn nuclear project, were scrapped by Hitachi in 2020, the UK government recently announced that Wylfa will house the UK's first three small modular reactors (SMRs), slated for operation by the mid-2030s. This has reignited hope for economic revival, but skepticism persists. Linda Rogers, a member of People Against Wylfa B (PAWB), argues that nuclear energy has left Anglesey as 'one of the poorest areas in Wales.' She advocates for investment in renewables, like tidal energy, citing the success of sustainable technologies: 'In 2024, 90% of new electricity was generated by renewables.'
Local councillor Aled Morris Jones, however, believes SMRs are the best economic hope for Anglesey. With a fragile local economy, a declining birth rate, and young people leaving due to lack of opportunities, Jones sees the UK government's investment as a source of 'certainty, confidence, and optimism.' Yet, he stresses the need for transparency: 'Tangible milestones and clear timelines are crucial to keep the community informed.'
As Wales marks a decade without nuclear power, Wylfa's legacy remains contested. What do you think? Is nuclear energy the answer to Anglesey's economic woes, or should the focus be on renewables? Share your thoughts in the comments – this debate is far from over.
