KTH Royal Institute of Technology, School of Engineering Sciences

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

Job description

We invite applications for up to two postdoctoral research positions in the general field of nuclear power safety. The successful candidates will join the Division of Nuclear Power Safety which conducts research on thermal-hydraulics and accident phenomena of risk importance to existing and future nuclear reactors, and also performs safety analysis for nuclear power plants, including design basis accident analysis and severe accident analysis with particular emphasis on light water reactors. The positions are associated with the following sub-topics:

  • Severe accident phenomenology in light water reactors (LWR); and
  • Thermal-hydraulics of future reactors.

The successful candidates are expected to conduct experimental and analytical/computational studies on (i) melt penetration in a pre-heated porous debris bed and underwater melt spreading, which are important severe accident phenomena in LWR; and (ii) natural convection and heat transfer of molten lead/LBE/salt coolant, which is paramount to the safety system design of some future (Gen-IV) reactors such as Lead-cooled Fast Reactors (LFRs) and Molten Salt Reactors (MSRs) - in particular for the residual heat removal system during accidents.

What we offer

  • International workplace.
  • A leading technical university that creates knowledge and expertise for a sustainable future.
  • Here you get colleagues with high ambitions in an open, curious and dynamic environment.
  • Help to relocate and be settled in Sweden and at KTH.

  • Apart from your own salary, you also get funding for travel and equipment, so that you can conduct an independent research activity. 



  • A doctoral degree or an equivalent foreign degree, obtained within the last three years prior to the application deadline.

    The successful applicants should have an outstanding research and publication record. Well-developed analytical and problem solving skills are a requirement.
