Welsh Anti-Nuclear Alliance relaunched amid concerns over new projects planned for Wales

A coalition of peace, environmental and social justice organisations has relaunched the Welsh Anti-Nuclear Alliance (WANA), calling for what it describes as energy sovereignty and a democratic, community-led debate on the future of Welsh energy.

The relaunch took place on March 1, with WANA bringing together groups including CADNO (Cymdeithas Niwclear Oesel), CND Cymru, the Low-Level Radiation Campaign, the Low-Level Radiation and Health Conference, No Nuclear Llynfi, PAWB (People Against Wylfa-B), Stop Hinkley and Welsh Nuclear Free Local Authorities.

First established in 1980 by a broad coalition that included former MP Paul Flynn, CND Cymru, the Central Wales Energy Group, farmers and environmentalists, WANA served as a vehicle for anti-nuclear campaigning for decades. Its work was later dispersed among individual organisations during a period of relative calm. With nuclear energy and defence projects once again high on the political agenda, campaigners say the time is right to revive the alliance.

WANA says it will focus on promoting what it calls “true renewable” energy generation while highlighting concerns around nuclear power and its links to military infrastructure.

A number of nuclear-related projects are currently proposed or under development in Wales. In November, the UK Government announced that Wylfa had been selected as a pilot site for Small Modular Nuclear Reactors (SMRs). Texas-based firm Last Energy has also set out plans for SMRs at the former Llynfi Power Station site between Maesteg and Bridgend. Other projects linked to the AUKUS alliance, including radar capability and submarine development, are expected to involve sites in Pembrokeshire and Cardiff. Nuclear development has also been suggested at locations including Aberthaw and Trawsfynydd.

WANA argues that decisions around these projects have often proceeded without sufficient input from Welsh communities. It says Wales has a long history of industrial exploitation, citing the decline of coal mining and heavy industry and more recent job losses in Port Talbot as examples of communities left behind after economic extracti

The alliance has published a manifesto calling for a “nuclear power and weapons free, sustainably powered, and peaceful Wales”. It raises concerns about public spending, the cost-of-living crisis, the climate emergency and what it describes as a lack of energy sovereignty. It also calls for greater debate around the links between civil and military nuclear programmes and for the devolution of the Crown Estate to Wales.

A WANA spokesperson said the alliance aims to bring campaigners together to challenge what it sees as the risks and costs of nuclear development.

“The cost of nuclear is too high, the build-times too long, and the waste question remains unanswered,” they said. “Wales must engage in a debate about our energy future, including community control and benefits.”
