Nuclear Workforce Planning in 2026

BLOGBy Rullion on 04 February 2026

The UK’s nuclear sector is moving into 2026 with clear momentum. 

By September 2025, UK civil nuclear employment had reached just under 100,000 roles, a record high. Growth is being driven by a wider mix of programmes than many people assume. It’s not only large-scale nuclear new build; it’s also fleet operations, defuelling, decommissioning, supply chain activity, and emerging delivery models like Small Modular Reactors (SMRs) beginning to shape future nuclear workforce planning. 

At the same time, government direction is becoming clearer. The UK’s long-term nuclear sector plan is increasingly defined through national roadmapping and policy signalling with an emphasis on sustained nuclear capability through to 2050. And that has implications for how workforce strategy is shaped in 2026.

Delve into (and jump to):

Why 2026 is a turning point for workforce planning in the nuclear sector

The nuclear workforce challenge is often described as a shortage issue. In reality, the pressure points in 2026 are more specific and more operational.

This year sits at the intersection of several competing demands:

  • Major nuclear new build delivery continuing at scale (including Hinkley Point C and Sizewell C)
  • Sustained demand across the existing nuclear fleet, including operations and nuclear life extension planning
  • Long-term decommissioning and waste management programmes continuing nationally
  • Rising expectations around safety, quality, assurance, and regulatory compliance
  • Growing demand for digitally enabled engineering and delivery capability
  • Increased attention on the workforce implications of SMRs, including the shift toward repeatability and standardised delivery models

In 2026, the same skill sets are being pulled in multiple directions at once: across different sites, delivery stages, and risk environments. The result is a more competitive hiring landscape, leading to longer lead times for scarce capability and higher consequences when workforce planning is reactive.

One sector, very different workforce needs

“Nuclear recruitment” is often treated as one market. Where in actuality, it’s several markets layered together, and the differences matter.

Workforce requirements shift dramatically depending on where a programme sits in the lifecycle:

  • New build delivery
  • Ongoing operations
  • Life extension activity
  • Defueling and decommissioning
  • Emerging delivery models like SMRs

Each stage behaves differently in terms of supply, scarcity, onboarding time, and compliance requirements.

Design & Engineering

Design and early engineering work tend to rely heavily on:

  • Systems and discipline engineering (mechanical, electrical, C&I)
  • Safety case and assurance capability
  • Governance, documentation, and regulatory awareness

This is also where “transferable skills” can genuinely work. But only when expectations are set properly. Nuclear environments reward structured thinking, documentation quality, and delivery discipline as much as technical capability.

This is increasingly relevant as SMR conversations mature. While the delivery model differs from large-scale builds, the fundamentals remain consistent: nuclear-grade quality mixed with engineering rigour and configuration control.

Construction & Commissioning

Nuclear workforce growth becomes most visible and most pressured here. In 2026, what becomes most challenging has more to do with readiness than availability. Projects don’t simply need people who can do the work. They need people who can deliver at pace to nuclear standards, within nuclear governance. Early workforce planning here is what can prevent project bottlenecks later. 

Construction and commissioning typically demand:

  • High-volume site delivery capability
  • Strong quality culture (inspection, welding, fabrication, assurance)
  • Commissioning expertise aligned to safety and compliance expectations
  • Logistics, HSE leadership, and interface management

Operations & Maintenance (O&M)

Operations is where nuclear becomes long-term. This is also where nuclear life extension activity becomes a real workforce driver in its own right. Extending the operating life of existing stations relies on retained knowledge and stable capability, and not just recruitment volume.

These roles depend on:

  • Reliability and asset performance expertise
  • Maintenance planning and outage delivery
  • Compliance, governance, and leadership maturity
  • Deep site knowledge and consistency

Decommissioning & Waste Management

Decommissioning is sometimes underweighted in workforce conversations, despite being one of the most sustained drivers of UK nuclear employment.

The Nuclear Decommissioning Authority’s (NDA) Draft Business Plan 2026–29 (published December 2025) reinforces decommissioning as a long-duration national programme, with ongoing workforce requirements across dismantling, waste handling, remediation, and programme leadership.

This work is often less visible than new builds, but it remains essential to the credibility and delivery of the UK’s wider nuclear programme.

The skills shaping nuclear hiring in 2026

Demand in nuclear workforce planning isn’t only about headcount. It’s about the right capability, in the right place, at the right time, delivered to the right nuclear standards.

As we move through 2026, pressure remains high in areas such as:

  • Electrical engineering and C&I
  • Systems integration and commissioning
  • Quality, inspection, and assurance
  • Safety case and regulatory-aligned delivery roles
  • Project controls (planning, cost engineering, scheduling)
  • Construction management and interface coordination
  • Digital capability (safety, configuration control, performance)

What’s notable in 2026 is that these skills are needed across multiple programme types at once. Across the lifecycle, one theme remains consistent: technical skill matters, but so does the ability to operate inside nuclear governance, with process discipline, documentation quality, and assurance expectations playing a key part of the job.

Where nuclear workforce planning breaks down

Even with all this nuclear sector growth, one of the biggest friction points is the gap between nuclear talent having the right technical background and being fully ready for nuclear delivery environments.

That “missing middle” tends to show up in areas like:

  • Project-readiness and site-readiness
  • Compliance and assurance expectations
  • Safety culture alignment
  • Documentation standards and quality processes

Geography adds another layer. Large programmes require both regional workforce development and national mobilisation. Without both, pressure builds quickly in local markets. This is why early workforce activity matters. Early shaping of pipelines leads to early team stabilisation and less reactive delivery, especially when multiple programmes are driving demand simultaneously.

This is where an abundance mindset matters most. The constraint isn’t that talent doesn’t exist. It’s that readiness is uneven and pathways into nuclear delivery remain too narrow. When organisations invest early in conversion, onboarding and nuclear-grade standards, capacity expands quickly. When they don’t, scarcity feels permanent.

“The challenge in nuclear isn’t a lack of people. It’s that capability is arriving at different levels of readiness, at different times, across different programmes. Workforce planning is about aligning that, not just filling roles.”
— James Chamberlain, Nuclear, Sector Director, Rullion


What better nuclear workforce planning looks like

The most effective workforce strategies in 2026 share a few key traits:

Plan by lifecycle phase, not just job titles

Nuclear delivery depends on sequencing. Workforce planning needs to follow the demand curve across the lifecycle and not just the current open vacancy list.

This forward planning can noticeably start to reduce risk:

  • Clearer lead times
  • Better mobilisation
  • Fewer last-minute compromises on quality or readiness

Build structured routes for scarce and transferable capability

The sector can’t rely only on nuclear-experienced talent. But “transferable” doesn’t mean instant. Transitions work best when there is clear structure around:

  • Expectations and standards
  • Onboarding and compliance readiness
  • Progression pathways once inside the sector

Where skills are transferable but nuclear readiness takes time, Train to Deploy helps build job-ready nuclear talent by combining targeted training with your delivery standards, so people arrive ready to contribute from day one.

Invest in early careers with conversion in mind

The National Nuclear Strategic Plan for Skills includes commitments to scale early career routes, including the ambition to double apprentices entering the nuclear workforce by academic year 2025/26, with 2,500+ apprentices joining the nuclear workforce in 2024/25.

The differentiator is what happens after entry: development pathways, retention, and long-term capability building.

Treat workforce as delivery risk management

In critical infrastructure, workforce constraints don’t only slow hiring. They affect commissioning timelines, quality performance, and programme confidence.

This becomes even more important when the sector is balancing large-scale builds, fleet operations, life extensions, decommissioning delivery, and next-generation programme development such as SMRs.

“You can’t separate workforce planning from mobilisation. If screening, onboarding, and readiness aren’t designed for scale, the workforce exists on paper but not on site.” — Jayne Lee, Head of Candidate Services, Rullion


What major programmes are signalling in 2026

Sizewell C is a strong example of early workforce momentum, and it sits within a wider landscape that includes major delivery demand at Hinkley Point C and sustained activity across operational and decommissioning sites.

In the last month, Sizewell C has reported:

Early pipeline activity is already shaping workforce readiness, long before peak construction demand. This is the direction the wider market is moving in: earlier engagement, clearer forecasting, and more structured talent strategies across delivery phases.

The nuclear hiring landscape in 2026

2026 will continue to be a strong year for the UK nuclear sector, but it will also be a demanding one.

The organisations that deliver best will be those that approach nuclear workforce planning as a core part of programme execution:

  • Anticipating scarcity early
  • Building structured pipelines
  • Protecting delivery confidence through quality and readiness
  • Creating workforce models that can scale across multiple sites and phases

Rullion wins at 2026 Alstom Supplier CSR Awards

Rullion wins at 2026 Alstom Supplier CSR Awards

Rullion has been independently recognised by Alstom, one of the UK and Ireland’s largest rail organisations, for its work in protecting the health and wellbeing of people across safety-critical infrastructure. At Alstom's Supplier Corporate Social Responsibility Awards, held during its Supplier Day, Rullion won the Improve Health and Wellbeing Award for Large Companies. The awards recognise suppliers delivering meaningful social value across Alstom’s UK and Ireland supply chain, with entries judged by the customer teams who work closely with them. In its assessment, Alstom highlighted Rullion’s strong focus on preventing work-related ill health through robust risk management, as well as its understanding that wellbeing initiatives only make a lasting difference when they are supported by the wider culture. The feedback also described the breadth of evidence submitted by Rullion, including activity linked to an Alstom-hosted Inspire session. Wellbeing that supports real working lives At Rullion, supporting wellbeing is built into how we deliver workforce solutions rather than bolted on as a separate campaign. Our focus is on spotting pressure early, before it affects someone’s health and their safety on site, or the continuity of a client’s project. That means giving people consistent support, whether they are a permanent employee or a contractor working on a short-term assignment. Across the business, this is supported by trained specialists, practical manager guidance, and clear routes into help when someone needs it. This includes Mental Health First Aiders, I-ACT practitioners, our Wellbeing Warriors network, and partnerships with organisations such as Able Futures and Help@hand. In rail and other safety-critical environments, early support can make a real difference. Fatigue, stress, travel pressures, working patterns, and fitness-for-work concerns all need to be understood before they become a risk on site. This sits alongside the compliance frameworks rail employers already rely on, including RISQS and Sentinel, where workforce readiness and safety are closely connected. By staying close to people and giving managers the tools to respond, Rullion helps protect individual wellbeing while supporting safer, more reliable project delivery for clients. For clients, this joined-up approach helps protect individual wellbeing while supporting safer, more reliable project delivery. Supporting contractors in safety-critical environments Contractors are central to the UK rail workforce, often deployed on time-sensitive projects where compliance and site readiness leave little room for disruption. Rullion's role goes beyond placing people into roles. Our teams stay close to contractors across their assignments, so concerns surface early rather than at the point they affect a shift or a milestone. This means regular contractor engagement, proactive fatigue management, and direct conversations about travel, working patterns, medical compliance, and fitness for work. When we identify a risk, we work with the client to resolve it before it lands on site. Keeping contractors well and engaged is better for the individual, but it also supports the smooth running of large-scale programmes. A workforce that feels supported is more likely to remain prepared and able to work safely in demanding environments. A partnership shaped by shared standards This recognition is especially meaningful because it comes from a long-standing customer relationship. Alstom sees how Rullion operates day to day, and this award reflects the experience of the teams who work alongside us. It is also the second time Rullion has been recognised at Alstom’s Supplier CSR Awards, following our previous win in the Driving Equal Opportunity Award for Large Companies category. Being recognised twice, across two different areas, reflects Rullion’s wider role as a workforce partner committed to opening up access to opportunity and supporting the wellbeing of people across the rail supply chain and wider critical infrastructure programmes. Alistair Haigh, Executive Director at Rullion, said: “Being recognised by Alstom is a proud moment for us. Across critical infrastructure, supporting people well is fundamental to delivering complex projects safely and successfully. It is not a nice-to-have. This award reflects the care our teams show every day, supporting clients and contractors to create safer, healthier working environments. We're grateful to Alstom for the recognition and proud of the partnership we've built together.” Continuing to build healthier, safer workforces Workforce support has to hold up on-site, across depots, project sites and live safety-critical operations. Continuing to invest in wellbeing means helping people feel looked after while giving clients more stable, resilient, and engaged workforces. We sustain that by: Providing early support when concerns are identified Maintaining regular engagement with employees and contractors throughout their assignments Equipping managers with the guidance and tools to support their teams effectively Working closely with clients to promote safe, healthy, and sustainable working environments This is not only a rail story. It is part of Rullion’s wider role as a workforce solutions provider for critical infrastructure. In these settings, a well-supported workforce helps large-scale programmes move safely and reliably, with the people they need in place.

Why the ‘Nuclear Skills Gap’ Is the Wrong Conversation

Why the ‘Nuclear Skills Gap’ Is the Wrong Conversation

The nuclear skills gap is usually described as a shortage: not enough engineers, too few graduates, and a limited pool of people ready to support the next phase of UK nuclear delivery. But the nuclear skills gap may be the wrong starting point. The sector does need people urgently, but the bigger challenge is how we recognise and develop talent and connect them to the right opportunities. In that sense, the problem is not only a supply issue. It is also a hiring problem, a communication problem, and a workforce planning problem. Across the energy and nuclear sectors, the contradiction is hard to ignore. Employers say they cannot find the people they need, while early-career professionals and career changers are struggling to access roles they are capable of growing into. Demand is rising as the UK pushes ahead with nuclear new build, works towards net zero and plans for long-term infrastructure delivery. Yet the conversation is still often framed as a UK skills shortage, as though the only answer is to create more people with the right labels on their CV. That misses a more useful question. What if the talent already exists, but the sector is not always looking for it in the right way? Jump to: The skills gap narrative is too simplistic Careers aren’t linear, but hiring in nuclear still is Transferable talent is more prevalent than ever Why the future of work is reshaping what “job-ready” means in nuclear University isn’t the default route into nuclear careers How to close the skills gap in nuclear Adapting your workforce planning The skills gap narrative is too simplistic The phrase “skills gap” is useful because it creates urgency. It gives employers, educators, and policymakers a shared problem to rally around. But it can also flatten a much more complicated issue. When hiring teams talk about an employee skills gap, they often mean something specific: candidates are not arriving with the exact sector background or technical exposure listed on the job specification. In nuclear that caution is understandable. Safety, regulation, site knowledge, and procedural confidence all matter. However, when every vacancy is designed around a perfect match, the pool narrows before potential is even considered. Job descriptions can become filters rather than gateways. They reward people who already know how to describe themselves in nuclear language and discourage those whose expertise has been built elsewhere. That creates a disconnect between candidates and hiring managers. One side sees a role they cannot quite match. The other sees a CV that does not immediately translate. Miguel Trenkel-Lopez captured this neatly in his Hot Off The Grid conversation. Through Megawatt, Miguel has spoken to young people who say they have applied for roles and have been rejected despite having relevant skills. He has also spoken to companies who say they are trying to hire but cannot find people. His conclusion was blunt: “It’s not a skill shortage. It’s a communications failure.” This perspective changes the response the sector needs. If the problem is only a shortage, the answer is to keep pushing more people into the pipeline. If it is also a communication and translation problem, the sector needs to think beyond the skills gap and look at how talent is identified and developed. Careers aren’t linear, but hiring in nuclear still is Career paths have changed. People no longer move through one neat route from education to entry-level role and then specialist career. They build experience across different sectors. They move sideways and retrain. Or they discover an industry through advocacy, outreach, a graduate scheme, or a chance conversation. Hiring in nuclear has not always adapted at the same pace. Many nuclear roles are still assessed against linear criteria: a particular degree, a recognisable employer background, or a set number of years in a similar regulated environment. Those things may be relevant, but they are not the whole picture. When hiring models focus too heavily on direct experience, they risk missing candidates whose careers have given them the judgement, curiosity, discipline, and adaptability the sector needs. Yasmin Ali’s career is a useful example. She began in fossil fuel generation, including a coal-fired power station, before moving through gas, district heating, government, and clean energy. When she wanted to shift direction, recruiters tended to frame her by the role she had most recently done rather than the broader expertise she had built. She used her network to make the move, but not every candidate has access to that kind of informal bridge. That is one of the hidden weaknesses in current hiring models. They depend too heavily on candidates knowing how to translate themselves. In a complex sector like nuclear, that cannot be left to chance. Transferable talent is more prevalent than ever Between entry-level candidates and perfect-match hires sits a large group of overlooked people: transferable and adjacent talent. They may not describe themselves as nuclear candidates, but they often hold experience that could be highly relevant with the right assessment and development. Construction Large-scale infrastructure Manufacturing Energy & Utilities Defence Transport Major project delivery Compliance Safety Operations Regulated environments The barrier is rarely a total lack of ability. More often, it is that their experience is framed differently. A hiring manager may be looking for direct sector experience, while a candidate reads the same role and assumes they do not belong. If the search then relies too heavily on familiar keywords, people can be excluded before their potential is properly explored. This is particularly important for nuclear recruitment because the sector needs more than one kind of specialist. It needs engineers, but it also needs project managers, technicians, planners, safety professionals, commercial teams, supply chain expertise, communicators, and people who understand how large infrastructure programmes actually get delivered. The nuclear career opportunities are vast. The workforce required to build, operate, and maintain nuclear projects is wider than the public perception of the industry often suggests.A project planner from rail may already understand programme controls, stakeholder management, and how to work within complex regulatory frameworks. A safety professional from defence may have experience operating in highly controlled environments where compliance and risk management are critical. The underlying capabilities are often transferable, even when the sector terminology is different. Jens Christiansen’s route into nuclear shows how much difference exposure and connection can make. In Denmark, where nuclear power has long faced political barriers, he built his pathway through advocacy, university choices, networking, and an internship in Sweden. His story is not a neat linear funnel. It shows how interest becomes a career when people have access to the right guidance and opportunities. The lesson is clear. Talent may not always come from the expected source. The task for employers is to recognise talent earlier and create clearer routes into the nuclear sector. Why the future of work is reshaping what “job-ready” means in nuclear The expectation that candidates should arrive fully job-ready is becoming increasingly unrealistic. That is not unique to nuclear, but it is especially visible in a sector where the demand for specialised capability is increasing and experienced workers are retiring. There is a difference between 'job-ready' and 'development-ready' talent. A job-ready candidate can step into a role with minimal support. A development-ready candidate may not know every process on day one, but they have the underlying capability and adjacent experience to grow into the role with structured training and on-the-job exposure. Nuclear has always depended on learning in context. Site knowledge, safety culture, regulatory confidence, and procedural understanding do not develop through a CV alone. They are built over time alongside experienced teams, through real work. That means skills gap solutions cannot focus only on immediate vacancy fulfilment. They need to include long-term development routes, including train-to-deploy models, early careers support, mentoring, and clearer progression pathways. The sector cannot wait for fully formed talent to appear. It has to build the conditions for capable people to become nuclear-ready. University isn’t the default route into nuclear careers The previous conversation around nuclear education still matters. Universities play an important role in creating strong technical foundations, particularly for engineering and science roles. But they cannot be treated as the only answer. Young people are entering a much tougher employment landscape. Recent figures from the House of Commons Library put youth unemployment among 16 to 24-year-olds at 16.2%, at a time when infrastructure and energy employers are still talking about shortages. That should make the sector pause. If young people are struggling to access work while nuclear employers are struggling to hire, the issue is not only education. It is the bridge between education, awareness, and employment. Nuclear apprenticeships are part of that bridge. So are school outreach, early careers programmes, career-switcher pathways, and employer-led training. Daljeet’s story from the wider energy sector is a reminder that valuable careers do not always begin with university. She started as an apprentice, moved through customer operations and built a senior career in energy. As she put it, university is a good option for many people, but it is not the only option. That message matters for nuclear graduates too. The sector needs to make early career routes feel accessible and realistic. Not everyone will arrive already fluent in nuclear. The more important question is whether they have the potential to learn and contribute. How to close the skills gap in nuclear Closing the skills gap in nuclear starts with reframing the question. Instead of asking only, "Where are the people with this exact experience?" employers need to ask, "What expertise does this role truly require, and where else might that expertise exist?" That shift changes how roles are designed, how candidates are assessed, and how hiring teams think about risk. Job specifications need to focus more on outcomes than previous job titles. Transferable skills need to be mapped from adjacent sectors. Career pathways need to feel clearer for people who do not already know the industry. It also means treating nuclear workforce planning as a strategic activity and not a reactive response to vacancies. If employers know what expertise they will need in three, five or ten years, they can start building it now through apprenticeships, graduate programmes, train-to-deploy routes, redeployment, and cross-sector attraction. Adapting your workforce planning The nuclear workforce challenge is real, but it is not a simple absence of talent. It is a disconnect in how talent is defined and moved into opportunity. That is why the traditional model of matching people to jobs is increasingly misaligned with how nuclear careers actually develop. The industry needs a wider view of talent, one that recognises potential before it is packaged into familiar nuclear experience. For employers, the opportunity is significant. Better translation of skills means broader candidate pools, stronger retention and more resilient project delivery. For candidates, it means seeing a route into a sector they may previously have ruled out. The skills gap conversation is not wrong because skills do not matter. The skills gap is real. It becomes less useful when the conversation is limited to just the shortage. The better conversation starts with better routes into the sector. It also means recognising potential earlier and creating a workforce strategy that reflects how people are building their careers today. The UK’s and Europe’s nuclear ambitions will ultimately depend on people. And not just those already working in the sector. Those who could be, if given the right opportunity.
