Could Pembrokeshire be home to ‘hugely ambitious’ fusion power plant?

A LOCATION is needed host a prototype nuclear fusion power plant, which a government-backed programme plans to build by 2040.

The UK government is asking Pembrokeshire communities to put themselves forward as the site of a future fusion power plant.

Communities are being asked to step forward with proposals to house a prototype fusion power plant in a move that could propel them on to the global stage in a world first.

The site does not need to be near existing nuclear power stations but will need 100 hectares of land and a plentiful water supply. Ministers say the project would bring thousands of skilled jobs and be part of its planned “green industrial revolution” to tackle the climate crisis.

The UK programme is called Step – the Spherical Tokamak for Energy Production – and communities will have until the end of March 2021 to submit their nominations and will need to demonstrate that their local area has just the right mix of social, commercial and technical conditions to host the new plant – such as adequate land conditions, grid connection and water supply.

Nuclear fusion replicates the intense atomic reactions that power the sun and uses a hydrogen isotope found in seawater as fuel. It cannot produce a runaway chain reaction like conventional nuclear fission, which involves splitting atoms rather than fusing them together. The level of radioactive waste is also far lower. No exclusion zone will be needed around the site, officials said.

However, the technical challenges are enormous and the programme’s leaders acknowledge it is “hugely ambitious”. This is because fuel heated to 10 times the temperature of the sun has to be magnetically levitated to stop it melting the reactor vessel. Scientists and engineers have pursued the dream of limitless and clean fusion energy for more than half a century, but the first power stations remain decades away.

The project has been granted £222m to date by the government.

Communities have until March 2021 to submit their nominations, with the successful site chosen by the end of 2022.

“We want the UK to be a trailblazer in developing fusion energy,” said Alok Sharma, the business and energy secretary. He said communities had an “incredible opportunity to secure their place in the history books” by potentially helping the UK to be the first country in the world to commercialise fusion power.

The UK has the largest working fusion reactor in the world – called Jet – at the Culham Science Centre near Oxford. However, a far larger €20bn (£18bn) fusion reactor called Iter is being assembled in France, backed by the world’s biggest countries. It expects to create its first super-heated plasma by 2025 and reach full power by 2035, with the aim of demonstrating that more energy can be taken out than is put in.

The goal of Step is to show that a smaller and less expensive plant can create fusion power. Key to this is the spherical shape of the chamber that contains the plasma, which is more compact than the doughnut-shaped chamber being used at Iter.

However, this compactness means the Step system must have a much more efficient cooling system. Technology to achieve this is being tested in the Mega Amp Spherical Tokamak (Mast) experiment, also at Culham. But the Culham site is too small to host the Step project.

Prof Ian Chapman, the chief executive of the UK Atomic Energy Authority, which is leading Step, said: “Step is about moving from research and development to delivery. It will prove that fusion is not a far-off dream, but a dawning reality.”

Tim Luce, the chief scientist at Iter, said: “It is gratifying to see the UK make a firm commitment to continuing its historic leadership in magnetic fusion development. Step promises lower costs but faces various engineering and physics challenges, such as large stresses in the magnet structure and high heat fluxes to the wall. [But] first plasma in 2040 appears to be a realistic goal, assuming favourable and timely results in the present generation of spherical tokamaks.”

The UK is a participant in Iter due to its membership of Euratom, but it will leave the group after Brexit. However, officials say they are hopeful that the UK can rejoin Iter as an associate country.

The timetable for Step is to have a concept design by 2024, then a detailed engineering design allowing the start of construction in 2032 and operations to begin in 2040.

57-year-old due in court following alleged knife and stalking offences

A MAN has been charged with attempted murder following a serious incident in Carmarthen town centre last week.

Dyfed-Powys Police confirmed that James McKenna, aged 57, from Carmarthen, has been charged with attempted murder, possession of a bladed article in a public place, and stalking.

The charges relate to an incident in Carmarthen Park on Thursday (Jan 29), which prompted a significant emergency services response and caused concern among residents.

Police have not yet released full details of the circumstances, but officers were seen in and around the park area for several hours following the incident while enquiries were carried out.

McKenna is due to appear before Llanelli Magistrates Court on Thursday (Feb 5).

The Herald understands the case involves allegations of both violence and targeted behaviour towards an individual, with stalking listed among the charges.

Public concern

Carmarthen Park is a popular and busy public space used daily by families, dog walkers and joggers, and incidents of this severity are rare.

The news has prompted concern locally, particularly as the alleged offences include possession of a knife in a public place.

Residents have previously raised questions about safety in parks and open spaces across west Wales, especially during darker winter evenings.

Court proceedings

At this stage, the charges remain allegations and the case will now proceed through the courts.

Magistrates will decide whether the case is sent to Crown Court due to the seriousness of the attempted murder charge.

Further details are expected to emerge during Thursday’s hearing.

The Herald will be attending court and will provide updates as they become available.

Sex offender jailed after living off grid in Pembrokeshire and refusing to register

Man walked into police station after months avoiding authorities

A CONVICTED sex offender who told police he intended to live “off grid” rather than comply with legal monitoring rules has been jailed after handing himself in at a Pembrokeshire police station.

Christopher Spelman, aged 66, of no fixed address, appeared for sentence at Swansea Crown Court after admitting breaching the notification requirements of the sex offenders register.

The court heard Spelman was released from prison in Dorset on July 4 last year but immediately refused to provide police with an address, despite being legally required to do so within three days.

Instead, he indicated he planned to buy a tent and live outdoors.

Prosecutor Brian Simpson said officers subsequently launched a nationwide search when Spelman failed to make contact with police. Public appeals were issued and his case featured on the television programme Crimewatch.

Detectives believed he had been travelling around the UK using public transport and staying at campsites. He was known to have links to several areas including Merseyside, Manchester, Devon, Cornwall and Hampshire.

His whereabouts remained unknown until January 3 this year, when he walked into Haverfordwest police station and was arrested. It is unclear how long he had been in Pembrokeshire.

Spelman previously served seven years in prison after being convicted in 2014 of 12 counts of sexually assaulting a girl under the age of 14. He was placed on the sex offenders register for life.

The court heard this was not the first time he had failed to comply with the rules. After an earlier release in 2016, he again failed to register his address and avoided police for around five years before being caught.

He has 11 previous convictions for 29 offences.

Defence barrister Andrew Evans described the case as unusual and said his client had long disputed his original conviction and had expressed a wish to live “outside society”.

However, he said Spelman had gradually accepted that he remained subject to court orders and now wanted more stable accommodation and a chance to rebuild his life. The defendant asked the court to impose a custodial sentence so arrangements could be made for his future release.

Judge Geraint Walters noted there were signs Spelman wished to change but warned that any further breaches would result in longer prison terms.

With credit for his guilty plea, Spelman was sentenced to 10 months in prison. He will serve up to half in custody before being released on licence.

Ex-Ospreys captain was almost twice over limit in Pembroke town centre

Former Wales back row Jonathan Thomas has admitted driving through Pembroke town centre on Christmas Day when he was almost twice over the drink-drive limit.

This week Haverfordwest magistrates heard that Thomas, 43, was stopped by officers as he drove his Mercedes CLA 220 along The Green, Pembroke, at around 5pm on Christmas Day.

“The officers were very concerned at the manner of his driving, as the car was being driven erratically and was swerving to the other side of the road,” said Crown Prosecutor Sian Vaughan.

“When Jonathan Thomas got out of the car, the officers could see that he was having difficulty standing and was unsteady on his feet.”

Subsequent breathalyser tests showed Thomas had 62 mcg of alcohol in his system, the legal limit being 35.

Thomas, who has no previous convictions, pleaded guilty to the drink-drive charge and was represented in court by solicitor Jess Hill.

“He has family in the area and had travelled to spend time with them on Christmas Day,” she told the magistrates. “He’s very remorseful for his actions and hugely regrets his decision that day.”

Jess Hill concluded by saying that Thomas is currently “between jobs and living off his savings”.

Thomas, who gave his address as Main Road, Bredon, was disqualified from driving for a total of 18 months.

“The length of your disqualification reflects the fact that you were more than a little bit over the limit,” commented the presiding magistrates when imposing sentence.

He was fined £120 and ordered to pay £85 costs and a £48 court surcharge.

The former Wales back row left his role as Swansea RFC head coach at the beginning of December 2025 as a result of ongoing health concerns. He was forced to retire from playing in 2015 on medical advice after being diagnosed with epilepsy and is one of the 390 former rugby union players currently taking part in a concussion lawsuit against the sport’s authorities.

“Long-standing issues linked to the head trauma have caused me some concern recently and it has been impossible for me to give the role everything it needs,” he said in a previous interview with the BBC.

His rugby career started out with Pembroke RFC juniors before moving to Swansea RFC, which he captained when he was 19. He then joined the Ospreys where, over a ten-year period, he won four league titles and an Anglo-Welsh Cup. He was the youngest player to captain the Ospreys and, at the time of leaving, was the joint highest appearance holder, together with Andrew Bishop, on 188 appearances.

His international career saw him play for Wales at Under-16, Youth, Under-19, Under-21 and Sevens levels. He made his senior international debut against Australia in 2003, featured at the 2007 Rugby World Cup and was part of two Six Nations Grand Slam-winning sides in 2005 and 2008. Between 2004 and 2011, Thomas was included in every Wales Six Nations squad. In his appearances for Wales, he scored seven tries.
