Campaigners call for absolute protection for Welsh national parks from nuclear plants.

Nuclear Free Local Authorities and Welsh Anti Nuclear Alliance, 9th December 2025

In response to a consultation by Natural Resources Wales on creating a new Glyndŵr National Park in North East Wales, Welsh anti nuclear groups have joined the Welsh Nuclear Free Local Authorities in calling for the Welsh Government to provide absolute protection for Welsh National Parks and National Landscapes from the threat of new nuclear development.

After indicating they were undecided on the issue, the groups submitted the following collective response:

‘In responding to this consultation on the creation of a new Glyndŵr National Park in North East Wales, we wish to call upon the Welsh Government to provide for absolute protection in law for Welsh National Parks and National Landscapes from the threat of new nuclear development.

The National Parks and Access to the Countryside Act 1949 was passed with all party support. The first ten national parks were designated as such in the 1950s, including three in Wales in the Brecon Beacons, on the Pembrokeshire Coast, and in Snowdonia.

In 1974 a National Parks Policy Review Committee established the Sandford Principle that ‘priority must be given to the conservation of natural beauty’. The Environment Act 1995 established in law that the primary duties of National Park Authorities are ‘conserving and enhancing the natural beauty, wildlife and cultural heritage of the area comprised in the National Park’.

Nuclear development in a National Park is then completely at odds with these objectives. Consequently, we are disappointed that the new UK Government has not directly specified in its new siting policy for nuclear plants (EN-7) that National Parks and National Landscapes will be exempted from development. This despite a precedent having already been set, as the English Lake District has been rightly excluded from consideration as the location of the Geological Disposal Facility.

If the English Lake District is excluded from such development, then surely the Eryri, Bannau Brycheiniog, Afordir Penfro, and Glyndŵr National Parks are worthy of equal consideration?

For without equal protection, the National Parks and National Landscapes in Wales could be aesthetically blighted and radioactively contaminated from future nuclear development.

This is no idle threat as the situation at Trawsfyndd demonstrates……………………………………………………………………………………………..

We believe that Wales has sufficient natural energy resources (wind, sun, wave, tidal, hydro and geothermal) to provide for its own energy needs and notes that the Welsh Government has already embraced a policy to generate all domestic consumed electricity through renewable technologies.

Any new nuclear plants in Wales will be built at English direction, with Westminster money, to generate electricity for England whilst transferring the risk of accident, the resultant contamination of air, land, rivers, and sea, and responsibility for the immediate management of nuclear waste onto the people of Wales……………………………………………………..

Campaigners call for absolute protection for Welsh national parks from nuclear plants

Joint media release

In response to a consultation by Natural Resources Wales on creating a new Glyndŵr National Park in North East Wales, Welsh anti nuclear groups have joined the Welsh Nuclear Free Local Authorities in calling for the Welsh Government to provide absolute protection for Welsh National Parks and National Landscapes from the threat of new nuclear development.

After indicating they were undecided on the issue, the groups submitted the following collective response:

‘In responding to this consultation on the creation of a new Glyndŵr National Park in North East Wales, we wish to call upon the Welsh Government to provide for absolute protection in law for Welsh National Parks and National Landscapes from the threat of new nuclear development.

Nuclear development in a National Park is then completely at odds with these objectives. Consequently, we are disappointed that the new UK Government has not directly specified in its new siting policy for nuclear plants (EN-7) that National Parks and National Landscapes will be exempted from development. This despite a precedent having already been set, as the English Lake District has been rightly excluded from consideration as the location of the Geological Disposal Facility.

If the English Lake District is excluded from such development, then surely the Eryri, Bannau Brycheiniog, Afordir Penfro, and Glyndŵr National Parks are worthy of equal consideration?

For without equal protection, the National Parks and National Landscapes in Wales could be aesthetically blighted and radioactively contaminated from future nuclear development.

This is no idle threat as the situation at Trawsfyndd demonstrates.

Trawsfynydd is located at the heart of Eryri, formerly Snowdonia. Eryri is the largest National Park in Wales with the highest mountain in Wales, Yr Wyddfa, and attracts an estimated four million visitors per year. A Magnox nuclear plant was opened at Trawsfynydd in 1968 and operated until the 1990’s. Built in an ugly brutalist style, the plant jars against the marked beauty of the natural environment. The Nuclear Decommissioning Authority is now reducing the height of the structure to make it less obtrusive, but it will still look brooding and completely out-of-place in the park. And the redundant plant has a cooling pond complex that leaks radioactive materials into the soil and the nearby lake, and studies by academic Dr Chris Busby identified a heightened cancer risk amongst the local populace who eat fish caught from the lake.

Despite this historic obscenity, the Welsh Government has been so foolhardy as to establish a company, Cwmni Egino, to reindustrialise this pristine landscape with ‘the deployment of small nuclear reactors to generate electricity and also a medical radioisotope research reactor’, completely undermining the work of the National Park Authority which is dedicated to its preservation. [i]

This is a lunatic concept. New nuclear redevelopment at Trawsfynydd would be wholly inappropriate. It would be hugely damaging to the beauty of the locality; would lead to further radioactive contamination of the lake and the local environment; its operations would always be accompanied by a risk of an accident and the generation of further radioactive waste; be massively detrimental to the peace and quiet enjoyed by residents and visitors; and would dilute the historic dominance of the Welsh language in this area by attracting a non-Welsh speaking migrant workforce. Further any new nuclear development of Eryri must also have a significant impact on visitor numbers, and so the tourist economy.

These factors militate against any such redevelopment at Trawsfynydd and represent a set of reasons why nuclear power and national parks are completely incompatible.

The Senedd passed a unique piece of legislation that militates against nuclear development in national parks: the Wellbeing of Future Generations Act 2015. Public bodies in Wales are expected to pull together in achieving the aspirations outlined in the act, amongst them those for a Resilient Wales, defined as “A nation which maintains and enhances a biodiverse natural environment with healthy functioning ecosystems that support social, economic and ecological resilience and the capacity to adapt to change” and a Healthier Wales defined as  “A society in which people’s physical and mental well-being is maximised and in which choices and behaviours that benefit future health are understood.”

Creating a new National Park would certainly move Wales forward towards meeting these objectives, but nuclear with its inevitable damage to the natural environment and to human health will most certainly not.

We believe that Wales has sufficient natural energy resources (wind, sun, wave, tidal, hydro and geothermal) to provide for its own energy needs and notes that the Welsh Government has already embraced a policy to generate all domestic consumed electricity through renewable technologies.

Any new nuclear plants in Wales will be built at English direction, with Westminster money, to generate electricity for England whilst transferring the risk of accident, the resultant contamination of air, land, rivers, and sea, and responsibility for the immediate management of nuclear waste onto the people of Wales.

The Glyndŵr National Park is being named after a beloved Welsh freedom fighter who valiantly resisted English military conquest and the usurpation of Welsh sovereignty. In responding to this consultation, we are calling upon the Welsh Government to invoke the spirit of Glyndŵr and use the occasion of the new park’s creation to make clear to Westminster that they will resist to the utmost any attempt to impose nuclear development in any National Park in Wales, including at Trawsfynydd, and in his spirit they should also disestablish Cwmni Egino, which is working in contravention of this policy.

To do otherwise would convey the impression that Wales remains a rank colonial possession, rather than a nation in its own right, whose beautiful National Parks remain vulnerable to exploitation for nuclear development of the most egregious kind…………………….https://www.nuclearpolicy.info/news/campaigners-call-for-absolute-protection-for-welsh-national-parks-from-nuclear-plants/
