Experimental Nuclear Thermal Hydraulics

18th – 29th of April, 2016, Lappeenranta University of Technology, Finland

The Experimental Nuclear Thermal Hydraulics course is hosted by Lappeenranta University of Technology (LUT) in Lappeenranta, Finland. The course lasts two weeks and offers the participants an up-to-date hands-on experience of two-phase flow.

Course begins with a short introduction to two-phase flow modelling relevant to nuclear reactor systems, and proceeds to discuss scaling, similitude, basic measurement techniques, data processing, and advanced measurement techniques.

More than half of the course is devoted to tutored exercises and laboratory exercises using the facilities of LUT Nuclear Safety Laboratory. In the laboratory, where participants put the theory to practice, observing and interpreting the phenomena.

Upon completion of the course the students will be able to:

  1. describe basic measurement techniques for one- and two- phase flows,
  2. understand similitude and scaling,
  3. understand thermal-hydraulic phenomena occurring in nuclear reactors and containments, in normal and abnormal operating conditions,
  4. understand the interaction between experiments and codecalculations,
  5. describe advanced flow structure mapping techniques (e.g. wire mesh sensing, particle image velocimetry).
