How to become a nuclear engineer

Solve the world's most complex problems

Nuclear engineers are at the forefront of solving some of the most pressing challenges facing our world. They work on developing clean energy systems, advancing medical technologies and supporting national defence. Becoming a nuclear engineer means entering a highly specialised, future-focused field where innovation and problem-solving drive real-world impact. 

In this guide, we’ll walk you through what nuclear engineers do, the skills they need, the qualifications required and the typical career pathway to become a nuclear engineer. Whether you’re just starting out in education or ready to make the switch, discover how UNSW can help turn your ambition into a meaningful role in engineering.   

What does a nuclear engineer do?

A nuclear engineer's role is wide-ranging, from designing reactors and energy systems to ensuring safety and regulatory compliance. Their responsibilities may typically include:

• designing and applying systems using nuclear processes

• developing radiological applications for healthcare, such as radiopharmaceuticals

• conducting research into reactor engineering, nuclear materials and fuel cycles

• monitoring nuclear safety, security and environmental impact 

• ensuring compliance with national and international nuclear standards and regulations

What roles are available for nuclear engineers?

There’s a global skills shortage in qualified nuclear engineers, which means graduates are highly employable both in Australia and internationally. Whether you're drawn to energy, healthcare, research or defence, nuclear engineering offers a meaningful and in-demand career path.

Depending on your interests and expertise, you could pursue roles in: 

Steps to become a nuclear engineer

Becoming a nuclear engineer in Australia is a long-term journey that combines academic rigour, hands-on experience and ongoing professional development. Here's what the typical pathway looks like:

1. Complete an undergraduate engineering degree
   Start with a specialised qualification such as the Bachelor of Engineering (Honours) (Nuclear Engineering) at UNSW. This four-year degree builds a strong foundation in physics, mathematics, thermodynamics, nuclear safety, reactor engineering and materials chemistry.
   
   
2. Gain practical experience and industry exposure
   Throughout your degree, you'll participate in design projects, collaborative team challenges and opportunities to engage with industry partners such as the Australian Nuclear Science and Technology Organisation (ANSTO).
   
   
3. Consider postgraduate study to specialise further
   If you want to deepen your expertise or transition into nuclear engineering from another discipline, postgraduate study is a strong option. The Master of Engineering Science (Nuclear Engineering) at UNSW is a two-year program designed for graduates from traditional engineering backgrounds.
   
   
4. Pursue professional registration and ongoing development
   As you enter the workforce, you may choose to pursue professional recognition through Engineers Australia or equivalent bodies. Continuing professional development, through certifications, industry training or further study, will keep your skills current and open doors to leadership and specialist roles.

What qualifications do you need to become a nuclear engineer?

To become a nuclear engineer in Australia, you must first complete a recognised engineering degree with a focus on nuclear engineering or a related discipline.

Most nuclear engineers hold:

• a Bachelor of Engineering (Honours) (Nuclear Engineering) or equivalent four-year degree

• a Master of Engineering Science (Nuclear Engineering), particularly if transitioning from another engineering field

Postgraduate qualifications are especially valuable if you're looking to specialise, lead research projects or work in highly technical sectors like defence, aerospace or nuclear medicine.

According to Jennifer, one thing that sets UNSW's nuclear engineering program apart is the focus on safety.

"Our program at UNSW is designed not only to develop technical knowledge and skills, but also a nuclear mindset – dedication to excellence, accountability and a commitment to continual improvement, to name a few."

"While knowledge evolves, especially in a rapidly advancing, AI-driven world, and skills can be refined throughout your career, these professional attributes are fundamental and stay with you for life."

Future opportunities as a nuclear engineer

As a nuclear engineer in Australia, your career path is diverse and future-focused, offering the chance to make a lasting impact on energy, healthcare, national security and beyond.

Most nuclear engineers begin in technical or research roles. Once you build more experience in the field, you may choose to:

• specialise in high-impact sectors such as nuclear medicine or the defence sector 

• transition into leadership or consultancy by guiding teams, influencing policy or advising governments and organisations 

• pursue research and innovation through working with institutions such as ANSTO, universities or international research bodies

• contribute to Australia's energy future. As nuclear energy becomes part of the conversation around clean, reliable power, nuclear engineers will play a central role in shaping how Australia meets its energy and climate goals.

• work internationally. Nuclear engineering is a globally portable skill set. Graduates are in demand worldwide.

For Jennifer, her research on advanced nuclear fuels has led her down a path she never expected.

"These fuels have higher uranium density and better thermal conductivity than the conventional fuel used today. The potential benefits include longer reactor lifetimes and reduced nuclear waste."

"Recently, our team carried out an experiment at the Australian Centre for Neutron Scattering, where we were able to track the fabrication process of uranium nitride in real time. We were addressing a real-world problem and understanding more about a promising material that could help mitigate the energy crisis. It brought together many talented and driven people working together towards a common goal. That’s what excites me."
