What does a nuclear engineer do?
Nuclear engineers work at every stage of the nuclear lifecycle, from new build and operations through to decommissioning and waste management. Areas of specialism include reactor design, systems engineering, mechanical integrity, safety case production and radiation protection.
Working in sectors such as energy, defence and medical technology, nuclear engineers ensure compliance with UK regulations and help drive innovation in low-carbon energy generation. The role calls for strong technical expertise, risk management skills and a good understanding of safety-critical systems.
How much does a nuclear engineer make?
In 2026, nuclear design engineers with 1-3 years' experience typically earn around £45,000 across mechanical, electrical and civil disciplines, rising to around £52,000 with 3-5 years' experience. Senior engineers earn £60,000 to £80,000 (typically £75,000), and principal engineers with 7+ years' experience command £80,000 to £110,000 or more, typically £90,000. Safety case engineers earn £40,000 to £55,000, rising to as much as £95,000 at principal level, while contract rates inside IR35 range from £38 per hour at mid-level to £85 per hour for principal EC&I engineers. Because nuclear engineering covers many different subsections, salaries vary from one area to another.
