About this position

TU Delft is advertising a PhD position in Experimental Analysis of Boiling Instabilities in Advanced Nuclear Steam Generators at the Faculty of Mechanical Engineering, within the Process & Energy department. The project focuses on understanding and characterizing boiling instabilities in helical steam generators for advanced nuclear reactor concepts such as high-temperature gas-cooled reactors and molten salt reactors.

You will help design and build a laboratory steam generator setup in the first year, working with technicians and a supervisory team. After that, you will study the behavior of boiling instabilities experimentally and compare the results with a numerical model. The research sits at the intersection of thermodynamics, heat transfer, fluid mechanics, transport phenomena, and transient modelling, with strong relevance to nuclear energy systems and thermal fatigue in steam generator tubes.

Eligibility highlights include an MSc in chemistry, physics, mechanical engineering, or a similar field, experience with experimental techniques and design of experiments, strong affinity with thermodynamics and transport equations, interest in the nuclear industry, and good communication/teamwork skills. A knowledge embargo exemption is required for this vacancy, and English proficiency is expected according to TU Delft Graduate School requirements.

The position is a 4-year PhD employment with an initial 1.5-year contract followed by a 2.5-year extension subject to a go/no-go assessment. Salary ranges from €3204 to €4051 gross per month, plus holiday allowance and an end-of-year bonus. TU Delft also mentions health insurance discounts, a monthly work costs contribution, and relocation support for candidates moving to the Netherlands.

Deadline: 15 November 2026. How to apply: submit your application online with a CV and motivational letter via the application button, addressed to dr. ir. Jurriaan Peeters.
