Job description
Nuclear Power Safety (NPS) Division seeks engaged postdoc to study in-vessel corium melt retention (IVMR) in small modular reactor (SMR) of PWR type, and (ii) ex-vessel melt-coolant interactions and melt spreading. The project is supported by Swedish Radiation Safety Authority (https://www.stralsakerhetsmyndigheten.se/). The IVMR research will be towards adaptation of the conventional IVR methodology developed for and used in the medium- and large-power PWRs and its further implementation in new SMR designs. The expected results are connected with demonstration of potential efficiency of the IVMR strategy, which can significantly improve SMR safety performance by preservation of integrity of reactor pressure vessel, i.e. the existing safety barrier.
What we offer
- A position at a leading technical university that generates knowledge and skills for a sustainable future
- Engaged and ambitious colleagues along with a creative, international and dynamic working environment
- Both computational and experimental research in well-equipped laboratories.
- Novel SMR concepts to be studied.
- Collaborations with organizations leading nuclear reactor safety research at national and international levels.
- Work in Stockholm, in close proximity to nature
- Guidance on relocating and settling in KTH and in Sweden
