PEMBROKESHIRE could be the location of an experimental nuclear fusion reactor, which could produce abundent clean energy, if the council backs plans for a site on land owned jointly between Valero oil refinery and Pembroke Power station.

Pembrokeshire County Council’s Cabinet will be asked next week (May 17) to support the project, which it is hoped could create limitless energy.

The officers of the council are recommending to Cabinet that members approve the nominated site being included on the list of UKAEA candidate sites.

Elsewhere in Wales, the Vale of Glamorgan Council is bidding for it to be built at the Aberthaw power station site.

Communities had until the end of March to nominate locations.

If approved the nuclear fusion station, the council’s officers say, could position Pembrokeshire at the international forefront of the clean energy revolution, bringing visibility to the community on a global stage. It was also recommended that the project will bring long-term and enduring environmental, employment, skills and economic benefits to the host community.

However, Greenpeace believes that nuclear fusion is an expensive distraction from the real agenda of providing environmentally benign, reliable energy supply. The campaign group gas also written to Parliament saying that the deuterium-tritium (D-T) fuel mixture used in nuclear fusion produces four times as many high energy neutrons per kilowatt-hour of energy produced than sandard nuclear fission.

Nevertheless the government has a concept programme called STEP, which is an ambitious programme for the conceptual design of a fusion power station. It is a UKAEA administered programme, currently with £220 million funding to produce a phase 1 concept design by 2024.

Beyond 2024, it is claimed, phase 2 intends to move into the engineering design and build phases to deliver the prototype of a commercially viable fusion plant. The prototype will hopefully demonstrate the commercial viability of fusion. The learning from this will enable the future development of a UK fleet of commercial fusion plants, the government said. The target date for the first fully operational plant will be 2040.

In November 2020, the UK Government released an open call to communities across the UK to identify sites that could accommodate a STEP power station, with the site near Valero being chosen.

A report to councillors sitting on the Cabinet states that unlike with conventional nuclear power, there is a benefit of limited risk of nuclear materials proliferation. This is because nuclear fusion doesn’t employ fissile materials like uranium and plutonium. There are no enriched materials in a fusion reactor that could be exploited to make nuclear weapons.

The STEP programme said that it seeks to maximise the recycling and re-use of materials and only use disposal routes where there is no other option.

It said to this end research is being carried out on suitable materials to minimise decay times as much as possible. Any radioactivity of the components in the tokamak structure is classed as low level and relatively short lived.
Fusion is regarded by Government as being carbon free, safe, low land use, low, manageable waste, reliable energy baseload with unlimited fuel.

Paul Miller, Cabinet Member for Economy, Tourism, Leisure and Culture on Pembrokeshire County Council said: “The Haven Waterway has provided livelihoods, underpinned by fossil fuels, for thousands of Pembrokeshire families, mine included, for more than 50 years.

“Its my job to help ensure the waterway continues to provide high skilled, engineering, science and technology jobs for the next generation of this county and so linked to our focus on climate change (and in addition to our existing multi-million pound commitments to supporting wind, wave and tidal clean power generation) my team have been exploring whether we can also support the development of clean, green fusion technology.

“It very early days in the UK Atomic Energy Authority’s site selection process but we’ll provide regular updates as things progress.”

What is nuclear fusion?

Fusion is the process that takes place in the heart of stars and provides the power that drives the universe. When light nuclei fuse to form a heavier nucleus, they release bursts of energy. This is the opposite of nuclear fission – the reaction that is used in nuclear power stations today – in which energy is released when a nucleus splits apart to form smaller nuclei.

To produce energy from fusion here on Earth, a combination of hydrogen gases – deuterium and tritium – are heated to very high temperatures (over 100 million degrees Celsius). The gas becomes a plasma and the nuclei combine to form a helium nucleus and a neutron, with a tiny fraction of the mass converted into ‘fusion’ energy. A plasma with millions of these reactions every second can provide a huge amount of energy from very small amounts of fuel.

One way to control the intensely hot plasma is to use powerful magnets. The most advanced device for this is the ‘tokamak’, a Russian word for a ring-shaped magnetic chamber. CCFE’s goal is to develop fusion reactors using the tokamak concept.

Advantages of fusion power

With increasing concerns over climate change and finite supplies of fossil fuels, we need new, better ways to meet our growing demand for energy. The benefits of fusion power make it an extremely attractive option:

No carbon emissions. The only by-products of fusion reactions are small amounts of helium, an inert gas which can be safely released without harming the environment.
Abundant fuels. Deuterium can be extracted from water and tritium will be produced inside the power station from lithium, an element abundant in the earth’s crust and seawater. Even with widespread adoption of fusion power stations, these fuel supplies would last for many thousands of years.
Energy efficiency. One kilogram of fusion fuel could provide the same amount of energy as 10 million kilograms of fossil fuel. A 1 Gigawatt fusion power station will need less than one tonne of fuel during a year’s operation.
Less radioactive waste than fission. There is no radioactive waste by-product from the fusion reaction. Only reactor components become radioactive; the level of activity depends on the structural materials used. Research is being carried out on suitable materials to minimise decay times as much as possible.
Safety. A large-scale nuclear accident is not possible in a fusion reactor. The amounts of fuel used in fusion devices are very small (about the weight of a postage stamp at any one time). Furthermore, as the fusion process is difficult to start and keep going, there is no risk of a runaway reaction which could lead to a meltdown.
Reliable power. Fusion power plants will be designed to produce a continuous supply of large amounts of electricity. Once established in the market, costs are predicted to be broadly similar to other energy sources.

UPGRADES have been completed to state-of-the-art equipment within the Port of Milford Haven’s navigation simulator suite at Milford Waterfront enabling marine professionals to receive bespoke specialist training. The virtual reality simulation system can safely replicate a range of scenarios that seafarers may experience in real world situations such as extreme weather conditions, emergency situations and escort tug work.

The upgrades provided by Netherlands-based company MARIN contain the latest hardware in terms of processing power and graphics, as well as upgrades to MARIN’s ‘Dolphin’ software, increasing the capability to create scenarios. These are complemented with new 4k visuals on 75” screens which increase the depth and field of vision, adding to the realism.

Recently, a training day was led by Training Pilot Captain Mark Johnson, assisted by ex-Pilot Andy Hillier, involving members of the Svitzer team as well as Pilots Matt Roberts and Ian Coombes. As part of the scenario, they were faced with a loss of engine power and steering along with worsening weather and sea conditions. The Pilots had to communicate with Svitzer in order to successfully instruct them on how to tow and direct a drifting tanker. While scenarios like these are uncommon within port operations, it is important to rehearse procedures that would be implemented if they are required and enhances participants’ skill sets.

Marine Pilot and Simulator Instructor, Captain Ewan McNicoll, said “This simulator suite has future proofed our training capabilities, both internally for Pilots and marine staff, but also externally for clients wishing to use the facility, be it for training purposes or research and development. We can create any type of scenario with any type of ship, ranging from practicing ship handling manoeuvres to emergency situations, it really is game changing! Working with our partners at MARIN has been a complete success and I am very proud of our new facility.”

RURAL Wales is seeing a major upgrade in mobile connectivity, with faster 4G now live in several areas. Seven locations across North, South West, and West Wales are benefitting from new 4G mast upgrades funded by the UK Government’s Shared Rural Network (SRN), aimed at closing the digital gap between rural and urban areas.

The upgrades, which went live on Thursday (Nov 14), bring improved 4G coverage to communities including Bontddu, Llanelltyd, Llanarmon Dyffryn Ceiriog, Penmaenpool, Tabor, Snowdonia National Park, and Bontgoch. Local businesses, emergency services, and residents are expected to benefit from faster internet access, which supports daily communication, business opportunities, and economic growth.

***There is a £170 million agreement with Openreach to provide gigabit-capable broadband to 70,000 remote Welsh properties***

Technology Secretary Peter Kyle said: “Fast, reliable connectivity is essential for modern life and should be available from Cardiff to the remotest parts of Wales. Today’s upgrades bring us closer to making this a reality.”

SUPPORTING DIGITAL INCLUSION

As part of the rollout, Peter Kyle and Telecoms Minister Sir Chris Bryant visited Ebbw Vale to discuss digital inclusion with charity and industry leaders. They met with representatives at BGfm, a digital inclusion hub in Blaenau Gwent, to learn about how connectivity impacts daily life in Welsh communities.

Telecoms Minister Bryant said: “We are working tirelessly to make sure rural communities aren’t left behind online.

“These upgrades mean businesses can now operate without connectivity limitations, 999 services are better equipped to respond, and residents and tourists can stay connected across the Welsh countryside.”

ADDRESSING CONNECTIVITY GAPS

An estimated 1.5 million homes across the UK remain without internet access, limiting people’s ability to access essential services such as banking and healthcare. In addition to the SRN upgrades, the Chancellor has allocated over £500 million in next year’s budget for digital infrastructure expansion, targeting these underserved areas.

Welsh Secretary Jo Stevens highlighted the importance of this investment, particularly for rural Wales, where fast, reliable internet can be transformative.

“Connectivity is critical for day-to-day life in rural areas – from supporting local businesses to ensuring emergency services are just a call away,” Stevens said.

The upgraded masts, previously limited to EE customers and emergency 999 calls, now serve a wider user base, bringing essential internet access to more people without requiring new infrastructure.

Ben Roome, CEO of Digital Mobile Spectrum Limited, said: “With the activation of five new SRN sites, Wales is seeing the tangible benefits of the Shared Rural Network, bringing crucial connectivity to rural communities.”

GOVERNMENT INVESTMENT IN REMOTE WALES

The improvements come alongside a £170 million agreement with Openreach to provide gigabit-capable broadband to 70,000 remote Welsh properties, helping future-proof digital access in even the most isolated locations.

The latest upgrades mark another step in the Government’s mission to improve mobile coverage and close the connectivity gap across Wales, creating opportunities and supporting economic growth across rural communities.
