Postdoc Position in Nuclear Engineering

Royal Institute of Technology

School of Engineering Sciences at KTH

Job Description

We are looking for a postdoctoral fellow to work on development of experimental methods for two-phase flows. We aim to develop a probe for measurement of void fraction and velocity at prototypic reactor conditions. The work includes development of methods for manufacturing miniature sensors and using these sensors in the HWAT facility.

The HWAT facility was developed to study thermohydraulic phenomena relevant to small modular reactors (SMRs). The work is part of a collaborative project in Europe and a national project supported by the Swedish nuclear regulator (SSM).
