Skills needed for a career in nuclear energy

The UK nuclear workforce now stands at 96,000, growing by 7,000 in a year. But demand is outpacing supply. By 2030, the UK will need a further 24,000 skilled workers, while over 40% of the current workforce is nearing retirement and women represent just 22% of the sector.

The skills needed for a career in nuclear energy combine technical expertise with strong transferable capabilities. While engineering and scientific knowledge remain central, the sector also relies on professionals who can manage projects, analyse data and adapt to complex, highly regulated environments.

As the industry evolves, particularly with the development of new build programmes and SMRs, demand is growing for a broader mix of skills across both traditional engineering and emerging digital disciplines.

Key skills and qualifications in demand

A career in nuclear energy typically combines formal qualifications with technical and practical experience. While engineering and scientific backgrounds are highly valued, there are multiple entry routes into the sector.

• Engineering and scientific qualifications - degrees at all levels (BSc, MSc or PhD) are highly regarded, particularly in disciplines such as mechanical, electrical, control and instrumentation engineering, as well as physics, chemistry and nuclear engineering. These provide the foundation for many technical and specialist roles across the industry.

• Software and safety-critical systems knowledge - as nuclear facilities rely on highly regulated, safety-critical systems, skills in software engineering and control systems are increasingly important, particularly for roles involving compliance with standards such as IEC 60880 and IEC 61513. At the same time, digital capability is evolving, with skills in artificial intelligence (AI), machine learning and data analysis becoming more relevant across plant operations, safety monitoring and project delivery. As the sector adopts more data-driven approaches, often described as “Nuclear 4.0”, professionals who can combine digital expertise with an understanding of nuclear environments are in growing demand.

• Vocational training and technical pathways - vocational qualifications and hands-on training are essential for many maintenance and safety-focused roles. Apprenticeships remain a key route into the sector, particularly for trades and technician-level careers.

• Apprenticeships and graduate schemes - structured entry pathways are widely available across the industry. Programmes such as those delivered at major UK projects and by organisations like the Nuclear Decommissioning Authority (NDA) combine formal training with practical experience, supporting early careers development.

• Work and learn programmes - some employers offer hybrid schemes where individuals split their time between university study and on-the-job experience. These are common in areas such as project management, project controls and engineering, providing a direct route into the industry while building recognised qualifications.

• Project and transferable skills - alongside technical expertise, the sector values skills in project delivery, problem-solving, communication and data analysis. These are particularly important for professionals working across complex, multi-phase programmes.

Nuclear projects operate within strict regulatory frameworks and long-term programmes, from new build and SMR development to decommissioning and waste management. As a result, employers look for a combination of recognised qualifications, technical capability and the ability to work safely and effectively in highly controlled environments.

Types of nuclear jobs: from entry-level to specialist roles

When people think of nuclear jobs, they often picture reactor operators working inside power plants. In reality, nuclear sites operate more like small cities, employing thousands of people across a wide range of disciplines.

From early-stage design through to decommissioning, the sector relies on a mix of technical, operational and project-based roles. This makes nuclear one of the most diverse career paths within UK infrastructure, with opportunities at every level.

Core nuclear roles

Engineering roles - nuclear engineering jobs span civil, mechanical, electrical and control and instrumentation disciplines. Engineers are involved across the full lifecycle, from plant design and construction through to maintenance, upgrades and decommissioning.

Operations roles - nuclear operators, including control room and reactor operators, are responsible for the safe and efficient running of facilities. These roles require specialist training and a strong focus on safety and regulation.

Skilled trades and technicians - welders, fitters, electricians and technicians play a critical role in keeping sites operational. These hands-on roles are essential during construction, outage periods and ongoing maintenance.

Safety and compliance - given the regulated nature of the industry, roles such as Radiation Protection Technicians and safety advisors are central to ensuring compliance and protecting both people and the environment.

Digital and IT specialists - as nuclear facilities become more advanced, there is increasing demand for IT, cybersecurity and data specialists to support and secure critical systems.

Project management and planning - large-scale nuclear projects require experienced project managers, planners and commercial professionals to coordinate complex programmes, often spanning many years.

Nuclear outage, commissioning and project roles explained

Alongside permanent operations, many nuclear careers are built around project-based work, particularly in outage, commissioning and major infrastructure programmes.

Outage roles - outages are planned shutdown periods where maintenance, repairs and upgrades take place. These projects require large numbers of skilled workers in a short timeframe, including engineers, technicians and specialist contractors. For many, outage work provides a flexible entry point into the sector.

Commissioning roles - commissioning involves testing systems and equipment before a facility becomes fully operational. This phase demands a high level of technical expertise, with roles focused on validation, performance testing and safety assurance.

Project-based roles - from new build developments and SMRs to decommissioning programmes, nuclear projects rely on multidisciplinary teams. These roles often suit professionals with experience in infrastructure, energy or construction who are looking to transition into the sector.

Small modular reactors (SMRs) and the future nuclear workforce 

SMRs are part of a global shift in nuclear energy. According to BBC News, more than 80 designs are currently being developed across multiple countries, reflecting growing interest in smaller, more flexible nuclear solutions.

In the UK, SMRs are seen as a way to expand nuclear capacity, strengthen energy security and support domestic manufacturing. Early investment is already translating into workforce demand. In 2022, Rolls-Royce SMR launched a major recruitment campaign, with plans to hire around 400 roles in its initial phase. Longer term, the programme is expected to support up to 40,000 UK jobs by 2050 and generate more than £52 billion in economic value.

Momentum is also building internationally. In the United States, major technology companies including Google, Microsoft and Amazon have signalled future demand, driven by the energy requirements of large-scale data centres. Across markets, both public and private investment will be needed to move SMRs from concept to commercial deployment.

How to start a career in SMRs

Starting a career in SMRs follows similar pathways to the wider nuclear sector. Degrees in engineering, physics or related disciplines remain a strong entry point, alongside apprenticeships and graduate schemes linked to major programmes.

There is also increasing demand for skills in:

• Advanced manufacturing and precision engineering
• Digital design, modelling and simulation
• Project management and systems integration
• Safety-critical and regulated environments

For those already working in engineering, energy or infrastructure, SMRs offer a clear transition route. Many of the skills used in large-scale projects, from design and construction to commissioning and operations, are directly transferable.

As SMR programmes move from development into delivery, demand for skilled professionals is expected to grow quickly. For both early careers and experienced professionals, this makes SMRs one of the most accessible entry points into the future of nuclear.

Security checks needed to work in nuclear

Because nuclear is part of critical national infrastructure in most countries, security standards are consistently high. Anyone working in the sector will need to complete background checks before starting a role, regardless of location.

The exact requirements vary by country and project, but entry-level screening typically includes:

• Identity verification
• Right to work in the country of employment
• Employment history checks (often covering the past few years)
• Criminal record checks, where applicable

In the UK, this is known as the Baseline Personnel Security Standard (BPSS). Similar baseline checks exist in other countries, forming the minimum requirement for access to nuclear sites. Read our guide to understand how to get a security clearance in the UK.

For more sensitive roles, particularly those linked to defence, national security or high-risk facilities, higher levels of clearance may be required. These can involve more detailed background checks, financial history reviews and longer processing times.

While the process is structured, it is generally straightforward if documentation is prepared in advance. Understanding the requirements early can help avoid delays, particularly when applying for roles on major projects or regulated sites.

How to find nuclear jobs in the UK 

Finding a role in nuclear can feel complex at first. The sector is highly regulated, project-led and often driven by long-term programmes rather than continuous hiring. As a result, opportunities are not always visible in one place.

Most nuclear jobs are linked to major programmes across new build, decommissioning, defence and emerging technologies such as SMRs. These projects are typically delivered by a network of operators, contractors and specialist suppliers, each with their own hiring processes.

For candidates, this means taking a targeted approach:

1. Follow major projects and programmes to understand where demand is growing
2. Build relevant skills and certifications aligned to regulated environments
3. Be open to entry points, such as contract roles or outage work
4. Work with specialist recruiters who have visibility of project pipelines
