76 Facts About How To Become A Nuclear Engineer

Updated: Dec 2, 2022

Nuclear engineers work to develop nuclear solutions such as handling tools, radiation shielding, reactor cores, and the instrumentation needed to operate and monitor nuclear equipment. You'll find yourself designing, building, running or decommissioning nuclear power stations.

They may monitor nuclear power plants for quality control and safety management by identifying design flaws, pinpointing construction and operation problems in complex equipment. Nuclear engineers may perform testing to see whether the practices used with nuclear material and waste are acceptable to humans and to the environment. They may also serve in emergency roles such as during and after nuclear accidents—even managing nuclear power plant shutdowns. Other nuclear engineering applications are in food production, submarine propulsion systems, medicine, industrial production, and nuclear weapon development.

Nuclear engineers work in an industry that both provides power to much of the world and poses a potential threat to humanity and the environment if not properly controlled and discarded. These professionals must have the proper education and training to succeed in this field. Nuclear engineers need to have a solid foundation of mathematics, science, observational skills, problem-solving, collaboration, and best safety practices. Additional certifications may add to an engineer’s employability and specialised nuclear engineering focus.

This guide provides an overview of key advice on how to become a nuclear engineer, including information about the roles, the requirements, day-to-day activities and what you can expect to be paid.

How To Become A Nuclear Engineer

What Nuclear Engineers Do

  • designing and building new plants and equipment

  • monitoring and measuring radiation levels

  • carrying out maintenance work

  • making sure the plant structure complies with legislation

  • being responsible for security and safety

  • supervising power-station technicians

  • planning safe methods of disposing of nuclear waste

  • Design or develop nuclear equipment, such as reactor cores, radiation shielding, and associated instrumentation

  • Direct operating or maintenance activities of operational nuclear power plants to ensure that they meet safety standards

  • Write operational instructions to be used in nuclear plant operation or in handling and disposing of nuclear waste

  • Monitor nuclear facility operations to identify any design, construction, or operation practices that violate safety regulations and laws

  • Perform experiments to test whether methods of using nuclear material, reclaiming nuclear fuel, or disposing of nuclear waste are acceptable

  • Take corrective actions or order plant shutdowns in emergencies

  • Examine nuclear accidents and gather data that can be used to design preventive measures

  • nuclear engineers are at the forefront of developing uses of nuclear material for medical imaging devices, such as positron emission tomography (PET) scanners. They also may develop or design cyclotrons, which produce a high-energy beam that the healthcare industry uses to treat cancerous tumors.

Responsibilities of nuclear engineers

  • understand the science behind how nuclear facilities work

  • analyse energy transmission, conversion and storage systems

  • solve design or operational problems with reactor cores and shielding, hydraulic and electrical systems, and complex instrumentation such as monitoring equipment

  • manage staff and budgets for complex design, construction, maintenance, expansion, safety and decommissioning projects

  • always keep the safety of people and the environment in mind, cooperate with local emergency services, and work with national, EU and international industry regulatory bodies

  • be aware of and address security concerns regarding the use, transport, storage and disposal of radioactive materials

  • interpret data and respond to emerging issues to ensure equipment is always working properlywrite reports, project plans and other documents that provide information about new facilities, existing processes, problems and solutions, and safety exercises for regulators, energy firms and co-workers in facility construction and management

  • discuss engineering issues with people from other fields, such as construction professionals, power grid managers and government officials

  • plan and assist with the safe decommissioning of facilities that have reached the end of their lifespan, including temporary and long-term disposal of high-hazard radioactive materialuse mathematical and computer models, and run pilot projects to try out new ideas.

Working Environment to consider when considering how to become a Nuclear Engineer

  • You could work at a power station, in a laboratory, in an office or in a control room.

  • You may need to wear safety clothing and use safety equipment.

  • Nuclear science and technology is always moving forward, which can be exciting.

  • Some people have negative opinions about the nuclear industry. You should expect to have to explain or defend what you do at times. Major companies in the field are very proactive about recruiting women and minorities. Initiatives are in place such as Women in Nuclear UK and EDF Energy's Diversity and Inclusion policy.

  • Currently, nuclear energy is a crucial part of the world's energy system. This means you will have a good level of job security.

  • There are opportunities to work abroad as many major companies operate internationally.

  • You'll need to dress appropriately for your role, which could range from office casual to formal (for meetings with major partners) to safety gear when on-site.
