Enriched Lithium: Advanced Nuclear & Fusion Energy

The Hidden Key.

Enriched lithium is a fundamental element for next-generation nuclear energy—integral to both fusion fuel cycles and advanced reactor cooling. Advancing lithium isotope separation technologies and building secure supply chains are critical to unlocking the full potential of fusion and modern fission infrastructures.

The Enrichment Challenge

Historically, lithium isotope separation relied on COLEX (column exchange), a mercury-based process now banned for environmental reasons. Today, the industry is pivoting to cleaner, scalable methods:

AVLIS (Atomic Vapor Laser Isotope Separation): Laser-based enrichment with high precision.
Electrochemical Separation: Mercury-free, using advanced materials like zeta-V₂O₅ for isotope selectivity.

Companies like Hexium are investing in these technologies to secure supply chains for future nuclear and fusion projects.

Why Lithium Matters in Next-Generation Energy

As the world accelerates toward clean energy solutions, enriched lithium is emerging as a critical enabler for both advanced nuclear reactors and fusion power plants. Its unique isotopes—Lithium-6 (Li-6) and Lithium-7 (Li-7)—play distinct roles in fuelling innovation and ensuring operational safety.

Lithium-6: Powering Fusion Through Tritium Breeding

Fusion energy promises limitless, carbon-free power, but it hinges on one scarce resource: tritium. Tritium doesn’t occur naturally in significant quantities, so fusion reactors must breed it internally. This is where Li-6 steps in:

Tritium Production: Li-6 reacts with high-energy neutrons inside breeder blankets to produce tritium and helium.
Essential for Self-Sufficiency: Without Li-6, fusion plants cannot sustain their fuel cycle.
Scale of Demand: A single demonstration fusion plant may require 10–100 tonnes of enriched Li-6, while commercial-scale reactors could need hundreds of tonnes.

Lithium-7: Supporting Advanced Fission Reactors

Li-7 is equally vital for advanced fission technologies, particularly Molten Salt Reactors (MSRs) and Pressurized Water Reactors (PWRs):

Coolant Chemistry: Li-7 maintains stable pH in reactor coolants, preventing corrosion and ensuring safety.
Molten Salt Reactors: Li-7-enriched salts act as heat transfer media and neutron moderators, enabling high-efficiency designs.

New career pathways are opening up in the nuclear industry. We are passionate that industry and educational institutions collaborate more to ensure people know about emerging careers while we are also working towards meeting future demands.

Future Talent: Women in Construction

Unlocking an Overlooked Talent Pool: Women in Construction & What Nuclear Can Learn 💡

As the construction sector accelerates efforts to diversify its workforce, the nuclear industry stands to benefit from similar strategies. Two recent initiatives highlight ways to systematically empower women in traditionally male-dominated fields—and their lessons are directly transferable to nuclear careers.

1. Women in Construction: The Power Within Training

Founded by Michaela Wain, Enas Fleming, and James Fleming, this UK initiative offers leadership and mindset development tailored for women entering and advancing in construction.

Leadership training through Motivational Intelligence (MQ): The program equips women with communication, resilience, and self-belief skills—key for navigating workplace biases.
Holistic development community: A supportive space combining free webinars, eBooks, and workshops creates a network of peers and mentors.
Proven impact: Participants are rising into leadership roles, leading cultural initiatives, and being promoted faster than industry averages.

2. Industry Push to Retain Women Apprentices

Data from the Construction & Industry Training Board reveals a 65% surge in women starting apprenticeships over five years; completion rates have more than doubled, from ~340 to 930 annually.

Despite this progress, women still occupy just 1% of site-based roles—underscoring the need for retention strategies.
Major drivers of early exits include lack of support, poor workplace culture, and few visible role models.
Programs blending technical skills with emotional resilience training, and creating mentorship structures, have shown measurable success: more women complete apprenticeships and take leadership roles.

Rebuilding Iran’s Nuclear Programme

The plan for Iran is to build eight new nuclear units in cooperation with Russia and supported by China. Iranian President Masoud Pezeskhian has talked about Iran’s need to produce medical technology, healthcare, and radiopharmaceutical products.

Pezeshkian said: “For our country, embracing advanced technologies and entering global competition is vital. Arrogant powers seek to deprive independent nations, including Iran, of access to modern technologies, keeping them dependent while they produce and sell medicines at exorbitant prices.

“Our products’ quality, effectiveness and affordability will make Iran a leader in this field,” he said, adding that the assassinations targeting Iranian scientists stem from the concern of major powers over Iran’s scientific and technological independence.

The International Atomic Energy Agency (IAEA) are barred from entering Iran and are also not allowed to monitor nuclear sites with cameras.

Iranian foreign minister Seyed Abbas Araqchi said,

“We have no desire to hold direct negotiations with Washington, but an agreement can be achieved through indirect negotiations,” he stated.

He emphasised the peaceful intent of Iran’s nuclear activities, but insisted that uranium enrichment will continue, arguing that external pressure or conflict would not force Tehran to abandon its nuclear advancements. “What could not be achieved by war cannot be achieved through politics.”

US President Donald Trump previously warned that if Iran’s facilities resume operations, he could order new strikes. “If Tehran does not pursue peace – future strikes will be far more extensive,” he said.

U.S. Disappointed with Rolls-Royce Build in Wales

As news of the first British site for Rolls-Royce SMR was announced, plenty of people celebrated while the U.S. was left disappointed by the decision.

We posted yesterday about this news, and although we want a strong bond between the UK and the U.S., British nuclear needs to plant its foot on home ground. We see no reason why other sites cannot be found elsewhere for future new builds; however, the site at Anglesey was something Westinghouse had their sights on.

The U.S. are interested in larger-scale nuclear projects, and utilising Westinghouse is seen as a faster, cheaper and already approved way to get cleaner, more affordable energy to the UK.

The AP300 leverages proven AP1000 tech for regulatory ease, offers simplified design for lower cost and faster construction with proven passive safety systems (gravity-fed cooling, natural circulation).

While everyone has their wants and needs over energy management and the nuclear future in Britian, we would do well to keep U.S.-UK relations strong, but really, only time will tell what’s next.

One thing’s for sure; a focus on skills and talent is going to be crucial. Britain has many nuclear and energy related infrastructure projects on-going and, in the future plans, the competition for top talent is rife and it’s only going to increase.

For those wanting to truly get ahead, we must address the skills gap at mid-career and look to succession plan up to the executive level. The sharing of expert knowledge and experience is crucial while transitioning talent into civil nuclear and energy. If we are to meet demand, we have to take our recruitment strategies seriously.

Rolls-Royce SMR lands in North Wales

Fantastic news today for British nuclear and the immediate region in Anglesey. We recently had a trip to the area and the boost this will have on local skills, and the economy is going to be life changing.

Supporting ~3000 jobs and billions of pounds of investment over the coming decade; this is set to support a generation of young people.

Touted as the golden age of nuclear, North Wales is on the map for many different reasons and the first of its kind nuclear is the newest.

Critical rail upgrades and manufacturing are just two of the areas that will feel the £2.5 billion investment, and this will further enhance British nuclear security, sustainability, and is a vital part of our modern industrial strategy.

Simon Bowen, Chair of Great British Energy-Nuclear, added:

“This is a historic moment for the UK and is another momentous step in realising Britain’s potential in leading the way on nuclear energy.

“These first SMRs at Wylfa will lay the groundwork for a fleet-based approach to nuclear development, strengthening the UK’s energy independence and bringing long-term investment to the local economy.

“Wylfa has a proud history of nuclear excellence, and we’re excited to build on that foundation to deliver jobs, training, and low-carbon energy for generations to come.”

Chris Cholerton, Chief Executive of Rolls-Royce SMR, said:

“We are honoured to have the opportunity to establish our UK fleet programme with an initial three units at the Wylfa site. Today’s announcement marks the first step in what will be a 100-year commitment to clean energy, innovation, and community partnership at Wylfa.

“This is a tremendous opportunity not just for North Wales but for the whole country, as we establish an enduring supply chain that will enable our fleet deployment in the UK and a large export programme, starting in Czechia.

“We will deliver nuclear power very differently by utilising modularisation and a high level of factory build, therefore minimising the impact on local people from infrastructure delivery. We are excited to be working with the local community to create jobs and growth.”

The Prime Minister said:

“Britain was once a world-leader in nuclear power, but years of neglect and inertia has meant places like Anglesey have been let down and left behind.

“Today, that changes. We’re using all the tools in our armoury – cutting red tape, changing planning laws, and backing growth – to deliver the country’s first SMR in North Wales.

“This government isn’t just reversing decline, it’s delivering thousands of future-proofed jobs, driving billions in investment, and providing cheaper energy bills in the long term.

“That’s national renewal in action: powered by British talent, powered by nuclear, and powered by a government that’s delivering for working people.”
